THERMOPLASTIC POLYMER COMPOSITION WITH ENHANCED WEAR PROPERTIES, METHOD OF IMPROVING RESISTANCE TO SURFACE WEAR AND SHAPED PRODUCT THEREFROM

摘要

A self-lubricating polymeric composition, characterized as a melt blend of a thermoplastic polymer and a lubricating system containing ultra high molecular weight polyethylenes, a polyester, acid metal salts, calcium salts, antioxidants and stabilizers. The composition may be prepared into shaped articles which exhibit improved surface wear resistance and coefficients of friction.
