Patent ID: 7645821

Claim:
A molding or molding composition composed of polyoxymethylene, comprising (A) from 0.1 to 50% by weight of a tribological modifier selected from the group consisting of polytetrafluoroethylenes, molybdenum sulfides, calcium carbonates, graft copolymers containing an olefin polymer graft base and at least one polymer grafted to the graft base selected from polyvinyls and polyesters, graft copolymers containing an elastomeric polydiene-based core and a hard graft envelope comprising a (meth)acrylate and/or (meth)acrylonitrile, ultrahigh-molecular-weight polyethylene powders, stearyl stearates, ester waxes composed of a fatty acid and of a monohydric alcohol, polyethylene waxes, amide waxes; and mixtures thereof, (B) from 0.01-0.5% by weight of a cyclic stabilizer which contains at least one nitrogen atom in the ring, and (C) from 0.05 to 1% by weight of at least one ester composed of a polyhydric alcohol and of at least one (C 24 -C 32 ) fatty acid; wherein the molding or a molding produced from the molding composition comprises a formaldehyde emission of less than 30 mg/kg, measured according to VDA 275 testing standard.
