Abstract:
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.
