THERMOPLASTIC POLYOXYMETHYLENE MOLDING MATERIAL WITH HIGH ABRASION RESISTANCE

摘要

Thermoplastic polyoxymethylene molding materials having high abrasion resistance contain (A) from 4 to 94.7 parts by weight of polyoxymethylene, (B) from 5 to 50 parts by weight of wollastonite, (C) from 0.2 to 5 parts by weight of N-hydroxymethylmelamines in which some or all of the hydroxymethyl groups are etherified with alkanols, (D) from 0.1 to 5 parts by weight of a silicone oil having a degree of polycondensation n of from 10 to 5,000 and/or (E) from 0.1 to 10 parts by weight of polyethylene and/or copolymers of ethylene and alpha -olefins having a molecular weight of from 100,000 to 1,000,000, the number of parts by weight of components A, B, C, D and E summing to 100, with or without (F) effective amounts of additives.
