Abstract

Polyoxymethylene compositions, articles comprising these compositions, and processes of making the compositions, comprising: a) at least one polyoxymethylene polymer; b) 0.02 to 1.5 wt. % of at least one amine polymer; c) 0.01 to 0.8 wt. % at least one polyamide; d) 0.02 to 0.9 wt. % of at least one nucleating agent; e) 0.01 to 0.5 wt. % of at least one formaldehyde scavenger; f) 0.02 to 0.5 wt. % of at least one antioxidant; wherein: the polyoxymethylene polymer has a melt flow rate of from about 1.5 g/10 min. to about 100 g/10 min. when measured according to ISO 1133; and an article molded from the polyoxymethylene composition exhibits formaldehyde emission of 3 ppm or less measured according to VDA 275 test method; and tensile creep to 10% strain at 80° C. and 25 MPa pressure of at least 6 hours, as measured according to ASTM D2990.
