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)

Thermoplastic ElastomersThermoplastic Elastomers
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 ...

Abstract for TR-288Abstract for TR-288
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 ...

Workshop on Physics of Poly-Domain Liquid Crystalline Elastomers Institute of Natural Sciences, SJTU 上海交通大学 自然科学研究院Workshop on Physics of Poly-Domain Liquid Crystalline Elastomers Institute of Natural Sciences, SJTU 上海交通大学 自然科学研究院
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, ...

Fully printed 3 microns thick dielectric elastomer actuatorFully printed 3 microns thick dielectric elastomer actuator
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 ...

Elastomer - WikipediaElastomer - Wikipedia
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 ...

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.

Hydrophobic silicone elastomer chamber for recording trajectories of motile sperms without adsorption - TechConnect Briefs
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.

High Field Electrostrictive Response of Polymers.
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
