Also disclosed is a method for making the disclosed polymer composition and an article of manufacture comprising the disclosed polymer composition.
Claims26
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.

A method of making a polymer composition comprising combining:
- 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 with 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 reinforcement filler dispersed within the thermoplastic polymer matrix.
