Objective: To compare the incidence of nonelective removal of single-lumen silicone and dual-lumen polyurethane percutaneously inserted central catheters (PICCs).. Study Design: A prospective cohort study was conducted with neonates in whom 247 PICC lines had been successfully inserted. Patients were assigned to either the single-lumen silicone group or the dual-lumen polyurethane group and nonelective removal incidence was compared using a logistic regression model.. Results: Incidence of nonelective removal in dual-lumen polyurethane PICCs (n =91) was 48.3% versus 34% in single-lumen silicone PICCs (n =156). Thus, dual-lumen polyurethane catheters had a significantly increased chance of nonelective removal compared with single-lumen silicone PICCs (P =.004). The most usual complication in dual-lumen polyurethane PICCs was suspected catheter-related bloodstream infection; in single-lumen silicone PICCs it was external rupture.. Conclusions: Dual-lumen polyurethane PICCs are associated with ...

All closed-cell polyurethane foam insulation made today is produced with a non-CFC (chlorofluorocarbon) gas as the foaming agent. Some polyurethane foam combines with a HCFC gas instead. These types dont insulate as well as insulation made with a CFC gas, but the non-CFC gas is less destructive to the ozone layer. However, these foams still have an aged R-6.5 per inch thickness. Their density is generally 2.0 lb/ft3 (32.0 kilograms per cubic meter [kg/m3]). There also are low-density open-cell polyurethane foams (0.5 lb/ft3 [8 kg/m3]). These foams are similar to conventional polyurethane foams, but are more flexible. Some low-density varieties use carbon dioxide (CO2) as the foaming agent ...

No, not in terms of the finishing at least. Its important if you want to make stuff that has low VOC emissions of course but doesnt appear to make any difference to how a finish dries, cures or maintains over time which is not surprising given the very slow outgassing of the formaldehyde.. FYI, polyurethane isnt enough of a description if you dont go on to clarify the exact type of product you used, as you did in the body of the Question. This is because there are multiples types of polyurethane finish and they are very different indeed. Waterbased polys are actually nothing like real polyurethane, oil-based polyurethane varnish. They are acrylic-suspension finishes with a little added polyurethane, and are not varnish in the true sense of the word despite being called that by many manufacturers. Basically the same product might be called acrylic lacquer by another maker and they name would be just as accurate.. ...

Presented work was undertaken to elaborate a repeatable method of fabrication of a hybrid (coated with livin cells) material that could be used in various blood circulatory support devices, e.g. artificial heart and its parts or vessels implants. The work involves chemical modification of already existing synthetic polymer - polyurethane - with evaluation after each step and cultivation of human endothelial cells on final material surface in order to indicate cells adhesion, growth and proliferation. A three-step chemical method of immobilizing collagen onto polyurethane surface was proposed. Final materials were non-toxic to endothelial cells and promoted cells proliferation and growth. Also, there was an expected change in cells morphology due to interaction with collagen. The whole process does not involve harsh conditions or complex equipment, therefore it is suitable to be utilized on a large scale.

Polyurethane foam functionalized with potassium O-ethyldithiocarbonate was evaluated as an extractant material for Hg(II). Several parameters such as pH, mass amount and extraction time were studied. Under the best conditions, a 86% of mercury extraction was achieved. Dubinin?Radushkevich isotherm model indicated that the nature of interaction between functionalized foam and Hg(II) is chemical. Regarding interferents, metallic ions Ag(I) and Sn(IV) have a significant influence on the Hg extraction percentage. In the case of silver, it had a synergistic effect increasing the percentage of mercury due to a metallophilic interaction. Also, once the mercury was extracted, its leaching from the functionalized polyurethane foam was evaluated by means of two sequential extraction procedures. In this way, the functionalized foam emerges as a good material for the removal and confinement of chemical species. Obtained results show that mercury extraction is successful even from complex solution and that ...

Polyurethane is relatively biocompatible, transparent, colourless, and autoclavable. In the field of ophthalmology, a polyurethane keratoprosthesis was well tolerated by rabbit eyes even 1 year after implantation. Unlike poly(methylmethacrylate) (PMMA), polyurethane is autoclavable; thus, it has been suggested as a potential material for intraocular lenses and keratoprostheses.16 Because of these encouraging results, we believed that polyurethane could be safely used as an extraocular physical barrier to adhesion formation. There have been no previous reports on the use of this material for delayed adjustable strabismus surgery. The ideal drug release devices for our purpose should fulfil the following criteria.22 Firstly, the device should provide a sustained and relatively uniform therapeutic concentration of the drug in a reliable and predictable fashion over an adequate period of time. Secondly, the device should be easily implantable or injectable, but must remain stable and non-migratory ...

like polycarbonate polyols, polycaprolactone polyols, polybutadiene polyols, and polysulfide polyols have been used to make polyurethane sealants.. Now, Chinese researchers have developed a novel ricinoleic acid based phosphorus and nitrogen-containing flame retardant polyols (FRPE) for polyurethane sealants. The flame retardant polyols were characterized by different characterization techniques.. Flame retardant polyurethane sealants (FR-PUS) were prepared by curing flame retardant polyols with methylene diphenyl diisocyanate (MDI-50). The flame retardant properties of the polyurethane sealants were investigated using limiting oxygen index (LOI), cone calorimeter testing (CCT) and thermogravimetric analysis (TGA).. Results showed that flame retardant polyols could enhance the thermal stability and flame retardancy of polyurethane sealants without adding any other flame retardant.. Now, industries manufacturing polyurethane sealants could produce them in a renewable way which will be ...

A method for preparing a foam-layered packaging material, which method includes the steps of providing an outer shell having a bottom wall and upwardly extending side walls defining an interior space and having an open top; pouring onto the bottom wall of the outer shell a predetermined quantity of a mixture of polyurethane foam-forming reactants; covering the open top of the outer shell with an inner protecting and cushioning layer so as to define a confined space within outer shell; and allowing the mixture of polyurethane foam-forming reactants to foam and completely fill the confined space with polyurethane foam while at the same time forming a direct bond between the foam and the inner cushioning layer over substantially the entire surface of the inner cushioning layer facing the confined space; wherein the predetermined quantity of the polyurethane foam-forming reactants is an amount effective to substantially completely fill the confined space with polyurethane foam and bond the foam with
Cellulose nanocrystals (CNC) were successfully obtained and modified with 1,6-hexamethylene diisocyanate (HE)!) by means of in situ polymerization varying the CNC/HDI molar ratio to evaluate the number of anchored chains to the CNC. The modification was examined by elemental analysis, nuclear magnetic resonance ((13)C NMR) and attenuated total reflection Fourier transform infrared spectroscopy (IR-ATR). Nanocomposites containing 1.5 wt% CNC, modified and unmodified, were prepared by solvent casting. Thermal and mechanical properties of the resulting films were evaluated from the viewpoint of polyurethane microphase separated structure, soft and hard domains. CNC were effectively dispersed in the polyurethane matrix and depending on surface chemistry, the nanoreinforcement interacts selectively with matrix nanodomains. This interpretation is supported by differences in thermal and mechanical properties of the nanocomposites and also confirmed by AFM images. Isocyanate rich cellulose nanocrystals ...

Like acrylics and alkyds, polyurethanes (PUs) represent an important class of industrial paints adopted by 20th and 21st artists; primarily by those creating outdoor painted sculptures (OPS). Because PU coatings offer a compromise between aesthetic and performance expectations, unachievable with other types of paints, they are commonly recognized as the most appropriate option for painted artworks intended for an outdoor setting. However, the PU class includes various systems and subgroups possessing very different properties. Through the FTIR-ATR study of 137 PU coating references from the Getty Conservation Institute (GCI) reference collection, this paper outlines the differences and the similarities existing, in terms of the composition, of two package solvent-borne, two package water-borne, one package water-borne and fluoropolymer polyurethanes. The comparison of the obtained FTIR-ATR results allowed determining markers helpful to discriminate specific PU subgroups by means of ATR-FTIR spectroscopy

Autori: Gabriela Ciobanu, Gabriela Carja, Octavian Ciobanu. Editorial: Materials Science and Engineering: C, 27 (5-8), p.1138-1140, 2007.. Rezumat:. Polymer-zeolite nanocomposite membrane separations represent a growing technological area with potentially high economic reward due to the low energy requirements. The use of polymer-zeolite nanocomposite membrane with incorporated zeolite nanocrystals has the potential to combine the advantages of polymers and zeolites while overcoming the shortcomings of both materials. This work focuses on the use of zeolite SAPO-5 nanocrystals for the preparation of the composite polyurethane membranes. SAPO-5 nanocrystals are synthesized in our laboratory and characterized by XRD and SEM analyses. Polymer-zeolite membranes were prepared by the incorporation of dispersible SAPO-5 nanocrystals into the polyurethane matrix. Polyurethane solutions were selected as organic network and a series of membranes, in which the content of zeolite ranges between 10 and 70 ...

Ask the Expert Question-and-Answer Archive. by Ron Joseph March, 2005. Solvent Entrapment on Paint Coatings Q. I am using a polyurethane coating HUMISEAL 1A33 and then drying it an IR Oven. Is this recommended as I believe the solvent gets trapped in the coating and it can never completely cure as there would be no oxygen. Would an acrylic coating be better? A. If you place the polyurethane or ANY other coating into an oven too soon, the solvents can become entrapped in the paint coating film. In some cases the solvents can remain in the coating for years and eventually cause blistering. Polyurethanes and epoxies are more prone to this than single component paint coatings because they cross link when they cure. You CAN cure a polyurethane or epoxy in an IR or convection oven, but first wait for several minutes to allow the solvents to flash off at room or even at a slightly elevated temperature. You will need to experiment with the flash-off time because it is affected by the film thickness of ...

0068] As mentioned, optional layers may be applied to automotive headliners during the molding step. Of particular interest are reinforcing scrims as described in WO 2002/04252, which may be applied to either or both sides of the fiber mat. Reinforcing scrims are suitably prepared from fibers of the types described before, and as before may be woven or nonwoven (or both). Reinforcing scrims of particular interest are made of an organic polymer such as a polyolefin or a polyester, or a natural fiber as described before. Such a scrim may also contain a quantity of glass fibers in addition to the organic polymer or natural fibers. The reinforcing scrim tends to be heavier, on a weight/unit area basis, than the mat of reinforcing fibers. As such, it tends to be less porous and less easily penetrated by the polyurethane-forming composition, although some penetration usually occurs. Even if little penetration occurs, the cured polyurethane functions as an adhesive to bind the scrim. The reinforcing ...
