Abstract
An elastomeric polymer composition is disclosed that is wear resistant at a broad range of temperatures. The composition contains a thermoplastic elastomer, such as a thermoplastic polyester elastomer, that forms a polymer matrix in products made from the polymer composition. The polymer composition may also contain a fluoropolymer and/or unmodified or functionalized ultra-high molecular weight polyolefin particles, such as ultra-high molecular weight polyethylene particles.
Claims24
A polymer composition comprising:
- a thermoplastic polyester elastomer present in the composition in an amount sufficient to form a polymer matrix phase;
- and
- a fluoropolymer, ultra-high molecular weight polyethylene particles, or a combination thereof, distributed throughout the matrix phase.
A polymer article comprising an elastic material comprising a polymer matrix phase comprised of a thermoplastic polyester elastomer, the matrix phase containing ultra-high molecular weight polyethylene particles dispersed therein, the ultra-high molecular weight polyethylene particles having a functionalized surface and wherein the ultra-high molecular weight polyethylene particles form an interfacial bond with the matrix phase, and wherein the material has a flexural modulus of from about 100 MPa to about 900 MPa @ 23° C.
