主权项

1. A polymer composition comprising:
a) from about 55 weight % to about 95 weight % of a thermoplastic polymer matrix; b) from about 5 weight % to about 20 weight % of a particulate polytetrafluoroethylene additive dispersed within the thermoplastic polymer matrix, wherein the particulate polytetrafluoroethylene additive has an average particle size less than about 40 μm, and wherein at least 90 weight % of the particulate polytetrafluoroethylene additive particles are smaller than about 60 μm; and c) from greater than 0 weight % to about 40 weight % of a reinforcment filler dispersed within the thermoplastic polymer matrix.
