Abstract
Polyoxymethylene with addition of a lubricant mixture composed of an aliphatic ester and of a polyethylene wax improves in-feed behavior into the injection-molding machine without substantially changing tribological behavior, when comparison is made with a polyoxymethylene which has only an aliphatic ester. The weld-line strength of the molding is also improved. The molding composition is used for moldings of any type with high tribological requirements running against hard materials.
Claims10
A thermoplastic molding composition comprising
- component (A) from 40 to 99.5 parts by weight of a polyoxymethylene homo- or copolymer
- component (B) from 0.5 to 10 parts by weight of a lubricant mixture
- component (C) from 0 to 60 parts by weight of additives,
- where the lubricant mixture comprises an aliphatic ester of a carboxylic acid having from 10 to 100 carbon atoms and a polyethylene wax, and the entirety of components (A), (B), and (C) is always 100 parts by weight.
