TPU stands for thermoplastic polyurethane and is thermoplastic transparent granule which can be meltdown when heated.
In 1937 two German workers produced a new polymer that had advantages over existing plastics made from polycondensation and was not covered by existing patients like that of Wallace Carothers polyesters patent. This polymer was polyurethane. Polyurethanes belong to the family of reaction polymers, whic...
Polyurethane is apolymer formed by the reaction of isocyanates and polyols. This reaction gives it the ability to be moldable, made different consistencies, rigid, and be customized to fit particular specs—like having a high tolerance for abnormally hot temperatures or be abrasion-resistant....

” Our customers include many Fortune 500 companies, most of whom have been customers for 20+ years. Their drive to become industry leaders has helped us do the same. A variety of additives can be incorporated into polyurethane to enhance wear properties, add lubricity, or produce parts that...
We observe a super-diffusion behavior and no apparent chainlength-dependent mobility of polymer chains on nanotubular membranes, which suggests that the additional out-of-plane fluctuations of flexible surfaces could influence the dynamics of adso...
2. The method as claimed in claim 1, wherein the gas separation membrane module has a plurality of laminates; each of the laminates comprising a permeate-side spacer for forming a permeate gas channel communicated with a hollow section in a core tube for collecting and discharging a permeate ...
polyurethane; polyureae; polycarbonates; polyarylenes; polyarylenesulfides; polyepoxides; polyolefins, such as polyethylene and polypropylene; polyalkadienes; biopolymers and their derivatives, such as cellulose, cellulose ethers and cellulose esters, such as ethylcellulose, nitrocellulose, cellulose acetate...
Alberta, researchers with the Advanced Composite and Materials Engineering Group at the University of Alberta (Edmonton, Alberta, Canada) have developed a novel, filament-wound, fiber-rein- forced polymer pipe with an intrinsically bonded polymeric internal liner that is capable of venting trapped ...
