Abstract
Reinforced polyoxymethylene compositions including 50 to 90 wt. % of a polyoxymethylene; 10 to 50 wt. % of glass fibers, wherein the weight of the polyoxymethylene and the glass fibers total 100 wt. %; 1 to less than 4.0 wt. % of a (meth)acrylic polymer additive, based on the total weight of the polyoxymethylene and the glass fibers; 0.1 to 5 wt. %, preferably 0.1 to 2.5 wt. % of a heat stabilizer; and 0.1 to 5 wt. % of an antioxidant, wherein the amounts of the (meth)acrylic polymer additive, the heat stabilizer, and the antioxidant are based on the total weight of the polyoxymethylene and the glass fibers.
