Abstract
A thermoplastic molding composition comprising (A) from 20 to 70% by weight of polyphenylene sulfide, (B) from 5 to 20% by weight of ultrahigh-molecular-weight polyethylene, (C) from 10 to 40% by weight of a fibrous reinforcing agent, (D) from 10 to 40% by weight of an inorganic filler, and (E) from 0 to 1% by weight of a lubricant and/or other additives is used to produce moldings, fibers and films having particularly good wear properties.
