Structural conformation of in vitro and in vivo aged orthodontic elastomeric modules. (1/162)

The objectives of this study were to investigate the structural characteristics of open and closed elastomeric modules in the as-received condition, and following (a) 24-hour in vitro loading determined as a 50 per cent extension relative to their original length; (b) 24-hour intra-oral exposure; (c) 3-week intra-oral exposure. Ten specimens of each type (open and closed) of the three brands of elastic chains were included in the study (total of 60). All specimens were subjected to (a) optical transmission microscopy utilizing phase contrast and polarized light modes, (b) micro MIR FT-IR spectroscopy, and (c) scanning electron microscopy and electron probe X-ray microanalysis. Stretched elastomers demonstrated a honeycomb pattern of filament detachment corresponding to strained areas. The chains possessing a well-differentiated inter-modular link presented higher strain concentration gradients located in the link. Phase contrast imaging revealed that the stress adsorption mechanism of these materials involved macromolecular chain orientation and elongation co-axially to the applied load. The specimens retrieved after 24 hours had acquired a proteinaceous film rich in alcohol groups with minimal evidence of phosphate mineralization, while the 3-week retrieved specimens presented precipitation of Ca- and P-forming calcium phosphates. The high protein content of the biofilm organized on the surface of these materials, as well as the calcification pattern found, were similar to a non-specific mechanism of film adsorption of biomaterials exposed to body fluids. The results have clinical implications for aspects of retraction control through sliding mechanics with the use of elastomeric ligatures, and the potential detrimental effects on dental and periodontal tissues such as decalcification and gingival inflammation, respectively. In addition, the experimental protocols adopted for the in vitro study of the force decay of elastomerics should be modified to include parameters pertinent to adsorption phenomena and calcification processes documented to occur in vivo.  (+info)

Adsorption and pharmacokinetics of cyclosporin A in relation to mode of infusion in bone marrow transplant patients. (2/162)

Two main factors that affect the pharmacokinetics of cyclosporin A (CsA) during 24-h durable intravenous (DIV) administration have been reported, namely physiological changes after bone marrow transplantation, and blood sampling through indwelling lines. In addition, it has been found that infusion sets made of polyvinyl chloride (PVC) markedly adsorb CsA. We conducted in vitro adsorption studies of CsA on infusion sets, and the administration routes that are used in the treatment of patients with bone marrow transplantation. We also examined the effects of administration route on CsA pharmacokinetics in clinical practice. The in vitro adsorption study using 30-mm segments of lumen from commercially available infusion sets showed that the degree of CsA adsorption per area of lumen made of PVC was significantly higher than that in those made of polyethylene (PE) or polybutadiene (PB), which showed no adsorption of CsA. Due to its adsorption, use of infusion sets made of PVC resulted in about a 40-50% loss of CsA dose, which affected the pharmacokinetic parameters during 24-h DIV, while those made of PE and PB did not. The use of non-PVC infusion sets should allow for accurate monitoring of CsA results, and provide cost benefit in the treatment of bone marrow transplantation.  (+info)

Fabrication of elastomer arterial models with specified compliance. (3/162)

A simple way of making elastic tubes using a mechanical lathe for precise control of the wall thickness is proposed in this study. These tubes are particularly useful for modeling properties of large arteries. Tubes with different geometric parameters and hence different elastic behavior have been made with a silicon elastomer (Rhodorsil RTV 1556). They have been created to be used for compliance measurements in hemodynamics research. Within a limited range of pressures, depending on the wall thickness, such tubes can be used to study models in which the compliance value is assumed to be constant.  (+info)

Fluoride-releasing elastomerics--a prospective controlled clinical trial. (4/162)

A prospective controlled clinical trial was undertaken to evaluate the effectiveness of stannous fluoride-releasing elastomeric modules (Fluor-I-Ties) and chain (Fluor-I-Chain) in the prevention of enamel decalcification during fixed appliance therapy. Forty-nine patients (782 teeth) were included in the experimental group, where the fluoride-releasing elastomerics were used. Forty-five patients (740 teeth) who received non fluoride-releasing elastomerics formed the control group. All patients had their elastomerics replaced at each visit. Enamel decalcification incidence and distribution were recorded using an index by direct clinical observation. In the control group enamel decalcification occurred in 73 per cent of patients and in 26 per cent of all teeth. In the experimental group the corresponding incidence was 63 and 16 per cent, respectively. The overall reduction in score per tooth produced by the fluoride-releasing elastomerics was 49 per cent, a highly significant difference (P < 0.001). A significant difference was seen in all but the occlusal enamel zones. The majority (over 50 per cent) of lesions occurred gingivally. The teeth most severely affected were the maxillary lateral incisors and mandibular second premolars. There was no difference in treatment duration between groups.  (+info)

A novel method of assessing the effectiveness of protective gloves--results from a pilot study. (5/162)

We have devised a novel method for evaluating the effectiveness of protective gloves and have undertaken a small study to assess this approach. Three types of glove were tested in a standardised simulation test with a permethrin-based pesticide. Prewashed cotton gloves were used to collect the samples. One was worn over the protective glove on one hand to measure the potential deposition of pesticide on the hands had the gloves not been worn. A second was placed under the protective glove on the opposite hand to measure the actual deposition of permethrin on the hands when the gloves were worn. This regime was reversed half way through each test in an attempt to prevent bias. Measurable inner glove contamination occurred on 25 out of 30 occasions. Geometric mean protection factors were calculated from the ratio of outer and inner sampling glove contamination, with average protection factors of 470, 200 and 96 being obtained for the two nitrile and PVC gloves, respectively. The PVC gloves were the least effective in preventing inner glove contamination, probably because the glove was thick and fairly inflexible, causing more pesticide to enter the glove around the cuff. Although the tasks were standardised, variability occurred due to worker behaviour and equipment failure. The spray pump failed on five occasions, resulting in higher levels of inner glove contamination and a geometric mean protection factor of 32. On the occasions when the pump worked correctly, the level of protection provided by the gloves rose dramatically with mean protection factors of 220 and 450 being obtained for workers categorised as "messy" and "tidy", respectively.  (+info)

Slip resistance of industrial floor surfaces: development of an elastomer suited to in-situ measurement. (6/162)

Slips contribute to 12% of occupational accidents. A slip resistant floor is a mean to prevent slipping accidents occurring in workshops. Floor slip resistance is often evaluated by measuring a friction index, proportional to the force opposing slipping of a reference elastomer on the floor surface under test. When implementing a portable appliance, slip resistance measurements carried out on lubricated floors were not stabilized. The authors advanced the hypothesis of oil impregnating the elastomer. A new elastomer suited to in-situ measurement has been developed to achieve stable measuring conditions. This study highlights the fact that the nature and characteristics of a reference elastomer must be specified when slip resistance measurements are carried out.  (+info)

Bacterial colonization associated with fixed orthodontic appliances. A scanning electron microscopy study. (7/162)

This investigation was undertaken to assess bacterial plaque accumulation adjacent to orthodontic brackets. Experiments were carried out on 11 subjects who were scheduled for orthodontic treatment including extraction of two or four premolars. Metal brackets were bonded to the premolars to be extracted using macro-filled bonding composite. A conventional elastomeric ring was placed around one bracket and a steel ligature wire around the bracket on the contralateral tooth. The subjects were told to continue their normal oral hygiene regimen. Teeth were extracted at 1, 2, or 3 weeks after bracket bonding. Scanning electron microscopic (SEM) examination of brackets, excess composite, and buccal enamel revealed that mature plaque was present on excess composite at 2 and 3 weeks after bonding, whereas plaque on the gingival enamel surface was still at an early stage of development. The results demonstrate that excess composite around the bracket base is the critical site for plaque accumulation due to its rough surface and the presence of a distinct gap at the composite-enamel interface. The method of ligation does not appear to influence the bacterial morphotypes on both composite and enamel surfaces.  (+info)

Strength decay of orthodontic elastomeric ligatures. (8/162)

AIM: To evaluate, over a 12-week period, the tensile strength (TS) and extension to TS of elastomeric ligatures (both clear and coloured) obtained from two companies. SETTING: Ex vivo study. METHOD: Seven replicates of five ligatures from two orthodontic companies were tested using an ex vivo assembly which simulated a clinical situation. RESULTS: The ligatures tested had a similar TS decay pattern, with the TS gradually decreasing over the duration of the study. The Unitek ligatures exhibited a greater TS than their respective Ormco ligatures. Generally, all of the ligatures tested experienced an increase in the extension to TS over time. The pre-stretching procedure used in this study did not produce any long-term detrimental effects on the TS and extension to TS of the ligatures tested. CONCLUSIONS: The results of this study confirm there are differences in TS, and extension to TS between clear and coloured elastomeric ligatures, and that some significant differences also exist between different brands of elastomeric ligatures.  (+info)

Back , Main menu , PSLC In 1839 Charles Goodyear invented a process called vulcanization, which made rubber more durable and more useful at hot and cold temperatures. Vulcanization crosslinks rubber. That is, it ties all the chainlike rubber molecules together to form one big molecule. This does a lot for the rubber, but it can also make rubber difficult to process. Think about it. A material made of one molecule cant really flow into a mold, and it cant be shaped or worked very easily. A material made of crosslinked rubber has to be shaped before it is crosslinked. Crosslinking also makes rubber difficult to recycle. Some kinds of synthetic rubber arent crosslinked, however. They can be molded and remolded again and again. They are called thermoplastic elastomers. Thermo- means heat, and plastic means moldable. Elastomer is just a fancy word that means rubber. So a thermoplastic elastomer is a rubber that can be molded when it is heated. While it is wonderful that thermoplastic ...

en] We investigate the microscopic morphology of thin films of symmetric triblock copolymers synthesized via a two-step living radical polymerization of n-butylacrylate and methyl methacrylate. These copolymers with low poly(methyl methacrylate) contents constitute a new class of potential thermoplastic elastomers with higher service temperature and oxidation resistance compared to conventional polydiene−polystyrene-based thermoplastic elastomers. The straightforward synthetic pathway allows for strict control of molecular weight, molecular-weight distribution, and composition. The presence in the copolymer of immiscible segments covalently bound to each other leads to phase separation on the nanometer scale. Regular organization of the phase-separated nanodomains is observed in real space by scanning force microscopy. The data point to a strong contrast in the local mechanical properties, corresponding to the microphase morphology. Cylinders of the minority phase are found to orient ...

This invention relates to a composition comprising a polybutadiene rubber containing a polymer obtained by block or graft polymerization of cis-1,4-polybutadiene with syndiotactic (syn)-1,2-polybutadiene, alone or blended with the other diene rubber, said syn-1,2-polybutadiene being crystallized and in a short fiber-like shape, and a breaking resistance characteristic and reinforcement characteristic being considerably improved by specifying the diameter and length of said short fiber, which is suitable for various parts of tire or industrial materials, and further relates to a composition of said polybutadiene rubber to which a carbon black is added for preferably used as a chafer or tread of tire, and still further relates to said composition to which a carbon black and an antioxidant are added for preferably used as a rubber blend composition for side wall.
Thermoplastic elastomer compositions of the present invention comprise a blend of from about 10 to about 50 parts by weight of a crystalline 1-olefin polymer, from about 80 to about 15 parts by weight of a styrene-butadiene rubber, and from about 5 to about 50 parts by weight of bitumen. The thermoplastic blends have unexpectant increases in properties, especially tear strength, tensile strength, high temperature (100 C.) tear strength, and smooth surfaces when injection molded. Moreover, the bitumen lowers the injection molding pressure, thus enabling larger parts to be molded. The compositions, which may be partially cured, also have excellent aging properties. The compositions are a true thermoplastic in that they can be repeatedly processed and yet maintain their good physical properties.

0046]The above thermoplastic elastomer composition is obtained by previously fusing and kneading the thermoplastic resin and the elastomer (uncured one in the case of rubber) by use of a biaxial kneader/extruder or the like, and thereby dispersing the elastomer component in the thermoplastic resin forming a continuous phase. When the elastomer component is cured, elastomer may be dynamically cured by adding a vulcanizing agent during the kneading. Additionally, although various compounding agents (other than a vulcanizing agent) may be added to the thermoplastic resin or elastomer component during the above kneading, it is preferable that these agents be previously mixed therein before the kneading. There is no particular limitation as to a kneader used for the kneading of the thermoplastic resin and the elastomer, and there can be listed a screw extruder, a kneader, a banbury mixer, and a biaxial kneader/extruder as examples of the kneader. For the purpose of kneading of the resin component and ...

1,3-Butadiene is used as an intermediate in the production of elastomers, polymers, and other chemicals. Of the 1,3-butadiene used in 1978, 44% was used to manufacture styrene-butadiene rubber (a substitute for natural rubber, produced by copolymerization of 1,3-butadiene with styrene), and 19% was used to produce polybutane elastomer (a substance that increases resistance of tire products to wear, heat degradation, and blowouts). Chloroprene monomer, derived from 1,3-butadiene, is used exclusively to manufacture neoprene elastomers for non-tire and latex applications. Commercial nitrile rubber, used largely in rubber hoses, seals, and gaskets for automobiles, is a copolymer of 1,3-butadiene and acrylonitrile. Acrylonitrile- butadiene- styrene resins, usually containing 20%-30% 1,3-butadiene by weight, are used to make parts for automobiles and appliances. Other polymer uses include specialty polybutadiene polymers, thermoplastic elastomers, nitrile barrier resins, and K resins®. 1,3-Butadiene ...

Cl. 260-75NH Claims ABSTRACT OF THE DISCLOSURE Polyurethane elastomers having improved hydrolytic stability are prepared from 4,4-methylene bis(cyclohexylisocyanate), neopentyl adipate polyester and an aromatic diamine. POLYURETHANE-UREA ELASTOMERIC COMPOSITIONS This invention relates to polyurethane elastomers, having improved hydrolytic stability, which are prepared from 4,4-methylene bis(cyclohexylisocyanate); neopenyl adipate polyester; and an aromatic diamine. It is known that polyurethane compositions can be prepared by chain-extending isocyanate-terminated prepolymers with a curing agent containing active hydrogen groups, such as a diamine, polyol, water and the like. The prepolymers are commonly prepared by condensation of a polyester or polyether with an excess of an aromatic diisocyanate. Where high performance elastomers are desired the preferred curing agents are aromatic diamines. However, the use of aromatic diamines presents a processing problem with many prepolymers. For ...

The International workshop on Physics of Poly-Domain Liquid Crystalline Elastomers will be held on June 9-11, 2011, at 601, Pao Yue-Kong Library(North Gate Entrance) Shanghai Jiao Tong University, Shanghai, P.R. China. The physics of the poly-domain phase of liquid crystalline elastomers (LCE) has attracted strong interest from many of us for quite some time. In addition to their potential for technological applications, these systems pose fascinating fundamental questions about the statistical mechanics of amorphous solids that possess internal orientational order. In contrast to conventional (i.e., fluid) liquid crystals, within a nelastomer deformations of the LC order necessarily induce elastic strains in the solid itself. These would impose a large elastic energy cost on the system as a whole - as we would naively expect from our intuition about elastic solids. Regardless of our intuition, the LC order within a liquid crystalline elastomer, when cross-linked under isotropic conditions, ...
This invention concerns a method for the preparation of polyurea elastomers, comprising: (a) reacting an amine chain extender with dialkyl maleate to form an aspartic ester, wherein the chain extender has a molar amount of amine groups that is greater than the moles of dialkyl maleate; (b) blending the aspartic ester with one or more polyoxyalkyleneamines to prepare a resin blend; (c) contacting the resin blend with an isocyanate under conditions effective to form a polyurea elastomer. This invention concerns a method for the preparation of polyurethane elastomers, comprising: (a) reacting an diamine chain extender with dialkyl maleate or fumarate, wherein the mole ratio of primary amine functionality in the diamine chain extender to dialkyl maleate or fumarate is more than 1:1; (b) coating a substrate with effective film forming amounts of the product of step (a), an isocyanate, and a polyhydroxyl compound under conditions effective to form a the

In this work we present a new fabrication technique to print thin dielectric elastomer actuators (DEAs), reducing the driving voltage below 300 V while keeping good actuation performance. With operation voltages in the kV-range, standard DEAs are limited in terms of potential applications. Using thinner membranes is one of the few existing methods to achieve lower operation voltages. Typical DEAs have membranes in the 20-100 um range, values below which membrane fabrication becomes challenging and the membrane quality and uniformity degrade. Using pad printing we produced thin silicone elastomer membranes, on which we pad-printed compliant electrodes. We then fabricated DEAs by assembling two membranes back to back. We obtain an actuation strain of 7.5% at only 245 V on a 3 um thick DEA. In order to investigate the stiffening impact of the electrodes we developed a simple DEA model that includes their mechanical properties. We also developed a strain-mapping algorithm based on optical ...
TY - ABST. T1 - Glycerol-silicone elastomers as active membranes for wound dressings and beyond. AU - Mazurek, P.. AU - Brook, Michael A.. AU - Skov, A. L.. PY - 2018. Y1 - 2018. N2 - A green and cheap silicone-based elastomer has been developed.1,2 Through the simple mixing-in of biodiesel-originating glycerol into commercially available polydimethylsiloxane (PDMS) pre-polymer, a glycerol-in-silicone emulsion was produced. This counterintuitively stable mixture became a basis for obtaining elastomeric composites with uniformly distributed glycerol droplets. Various compositions, containing from 0 to 140 parts of glycerol per 100 parts of PDMS rubber by weight, were prepared and investigated in terms of mechanical properties as well as optical and scanning electron microscopy. The materials were proven additionally to exhibit a strong affinity to water, which was investigated by simple water absorption tests. Incorporating glycerol into PDMS decreased the Youngs modulus of the composites yet ...
An elastomer is a polymer with viscoelasticity (having both viscosity and elasticity) and very weak inter-molecular forces, generally having low Youngs modulus and high failure strain compared with other materials.[1] The term, which is derived from elastic polymer,[2] is often used interchangeably with the term rubber, although the latter is preferred when referring to vulcanisates.[3] Each of the monomers which link to form the polymer is usually made of carbon, hydrogen, oxygen or silicon. Elastomers are amorphous polymers existing above their glass transition temperature, so that considerable segmental motion is possible. At ambient temperatures, rubbers are thus relatively soft (E ≈ 3 MPa) and deformable. Their primary uses are for seals, adhesives and molded flexible parts. Application areas for different types of rubber are manifold and cover segments as diverse as tires, shoe soles, and damping and insulating elements. The importance of rubbers can be judged from the fact that global ...

TY - JOUR. T1 - Clinical effectiveness of fluoride-releasing elastomers. I. T2 - Salivary Streptococcus mutans numbers. AU - Wilson, Thomas G.. AU - Gregory, Richard L.. PY - 1995/3. Y1 - 1995/3. N2 - The purpose of this study was to examine the effect of fluoride-releasing elastomers on salivary Streptococcus mutans numbers. Twenty-four patients with fixed orthodontic appliances were randomly divided into experimental and control groups consisting of 12 patients each. Conventional elastomers were in place while two baseline whole saliva samples were collected from each subject in both groups at their regular appointments. After the second baseline sample was taken, conventional elastomers were replaced with fluoride-releasing elastomers in the experimental group, whereas conventional elastomers were continued in the control group. Three saliva samples were then collected from all subjects at 1-week intervals. Conventional elastomers were placed in all subjects while two postexperimental saliva ...
TY - JOUR. T1 - Rheological Evaluation of the Isothermal Cure Characteristics of Medical Grade Silicone Elastomers. AU - McConville, C.. AU - Andrews, Gavin. AU - Laverty, T.P.. AU - Woolfson, David. AU - Malcolm, Karl. PY - 2010/5/15. Y1 - 2010/5/15. N2 - Silicone elastomer systems have been shown to offer potential for the fabrication of medical devices and sustained release drug delivery devices comprising low molecular weight drugs and protein therapeutics. For drug delivery systems in particular, there is often no clear rationale for selection of the silicone elastomer grade, particularly in respect of optimizing the manufacturing conditions to ensure thermal stability of the active agent and short cycle times. In this study, the cure characteristics of a range of addition-cure and condensation-cure, low-consistency, implant-grade silicone elastomers, either as supplied or loaded with the model protein bovine serum albumin (BSA) and the model hydrophilic excipient glycine, were investigated ...
This paper describes F-based dry etching and resulting surface properties of biocompatible silicone elastomer. The etch rate of polysiloxane and surface morphology was found to be highly temperature dependent. An increase in temperature results in a significantly higher etch rate and a lower surface roughness. Possible mechanisms of the etching process and the roughness formation on an elastomer surface are discussed. The polysiloxane surface was proved to have hydrophobic characteristics both prior to and after plasma exposure. The results of the preliminary cytotoxicity study are very promising: cell viability on a raw and plasma treated polysiloxane was found to be very high and comparable to control. Due to the acceptable etch rate and absence of toxic contaminations, a F-containing plasma is considered an excellent method for microprocessing of silicone elastomers intended for biomedical applications.

A one-part silicone elastomeric composition that is flowable or easily extruded is prepared by mixing a hydroxyl endblocked polydiorganosiloxane, a difunctional silane having two amido radicals, and an organic peroxide suitable for vulcanizing silicone rubber. A nonacidic filler is optional. After being put in place, the composition is exposed to moisture to activate a chain extension reaction that increases the molecular weight of the polydiorganosiloxane, to improve the physical properties of the cured silicone elastomer. After chain extension has taken place, the composition is heated to activate the organic peroxide, thereby crosslinking the composition into a silicone elastomer. The composition is useful as a potting and encapsulating material.
Okayama University, JP. Keywords: adsorption, artificial insemination, porcine sperm motility, silicone elastomer, trajectories. Sperm motility analysis is a representative method for evaluation of male fertility, since motility correlates with viability. The conventional method, commonly referred to as Computer-Assisted Sperm Analysis (CASA), to records motility and linear velocity (LV) utilizing a microscope with a charge coupled device. The advantage of CASA over manual observation is the absence of subjective calibration. It is difficult to record trajectories of motile porcine sperms and investigate LV related to fertility because sperms often adsorb to glass and plastic, which remarkably decreases their motility. To record the trajectories of motile sperms and investigate their velocity distribution quantitatively under a microscope, the use of transparent materials that do not promote adsorption of motile sperms is necessary. The candidate material is hydrophobic silicone elastomer ...
With the purpose of improving the mechanical properties of the polyamides, the possibility of combining polyamides with elastomers has been used. The low compatibility of the resulting blends leads to deficient mechanical properties, and therefore, it is necessary to add the compatibilizer to the mixture or to produce the compatibilizer during the melting mixture. Usually, at least one of the components must contain a reactive functional groups. In the present work, blends of polyamide 6 (PA 6) and epichlorohydrin elastomers, polyepichlorohydrin (PEPI), and the equimolar copolymer poly(epichlorohydrin-co-ethylene oxide), EGO, with different compositions were prepared by mechanical mixture using a Banbury-type mixer. The blends were characterized by rheological measurements, the Molau test, elemental analysis, Infrared Spectroscopy by Diffuse Reflectance, Transmission Electron Microscopy, and X-ray Diffractometry. The blends of PA 6 with PEPI and ECO are heterogeneous, showing a morphology of ...

It is well known that electrostrictive strains are proportional to the square of the applied electric field. It therefore appeared reasonable to assume that for some polymeric materials, a large acoustic thickness response might be obtained by application of high dc bias fields, approx. 20 MV/rn, to a film while driving the film with an ac signal to access the high slope region of the electrostrictive strain vs. applied field curve. Previous studies of crystallizing poly(vinylidene fluoride) (PVF2) from solution under high electric fields have demonstrated that gel-like samples of PVF2 with high content of the plasticizer tricresyl phosphate (TCP) could he subjected to electric fields as high as approx. 100 MV/m. Using this type of heavily plasticized PVF2, d sub T values approx. 4 Angstrom/V were obtained. Values of 9 Angstrom/V were obtained for a certain class of thermoplastic elastomer (i.e., a polyurethane). These d sub T values are considerably greater than those obtained from conventional

The coefficient of restitution entered the common vocabulary, among golfers at least, when golf club manufacturers began making thin-faced drivers with a so-called "trampoline effect" that creates drives of a greater distance as a result of the flexing and subsequent release of stored energy, imparting greater impulse to the ball. The USGA (America's governing golfing body) has started testing drivers for COR and has placed the upper limit at 0.83.In April 2006 issued a more detailed report using five of the top golf balls used by professional golfers. In this report facts about golf balls beyond the subject of COR are highlighted. Due to the nature of polymers (man-made plastics) where rates of stress & strain are not Newtonian like fluids, metals etc. Because of this COR is a function of rates of clubhead speeds and diminish as clubhead speed increase. The USGA clearly states that nothing much can be gained beyond 90 mph clubhead speed. In the report COR ranges from 0.845 for 90 mph to as low ...
