ABSTRACT:
A low wear polymeric composition exhibiting improved surface wear resistance and coefficients of friction characterized as a melt blend of a thermoplastic polymer and a lubricating system containing PTFE, pentaerythritol tetrastearate and fine particle, stearate coated calcium carbonate, a hindered amine, N,N'-ethylene bis-stearamide, and calcium ricinoleate. The composition is suitable for the preparation of shaped articles for use in fricitional environments.
