What is Polyurethane Elastomer?
Polyurethane elastomer is used in many diverse applications. The various polyurethane elastomers offer a broad range of hardness and processing characteristics.
Cast polyurethane elastomers, for example, are simply made by low-pressure mixing and pouring a degassed reactive liquid polyurethane resin into a mold, and the entire process can be done by casting machine.
These urethane materials have excellent abrasion resistance, and also have decent resistance to be attacked by oil, petrol and many common non-polar solvents.
In general, only strong based and acids, oxidizing agents and a few strong polar solvents affect completely-cured cast polyurethane elastomers.
Common finished polyurethane products made by casting polyurethane resin are printing rollers , press-on tires , industrial off-road tires , fork-lift tires and skate board wheels …etc.
These urethane materials have excellent combination of high elongation and tensile strength with high abrasion and environmental resistance, and the products can be mass-produced in precise dimensions.
Depending on the formulation, thermoplastic polyurethane elastomers can also have outstanding resistance to fuels, oils, solvents and chemicals.
Applications of thermoplastic polyurethane elastomers include many PU products, such as industrial hose, pneumatic tube, high-wear resistant engineering parts and footwear components…etc.
