Abstract
The present disclosure relates to a molding composition and to molded products made from the composition. In accordance with the present disclosure, the polymer composition contains a polyoxymethylene copolymer having a relatively low amount of comonomer units. The polyoxymethylene polymer is combined with at least one reinforcing fiber and a coupling agent. The above polymer produces a composition have a relatively high heat deflection temperature, while also having excellent mechanical properties.
Claims22
A product comprising a molded article, formed from a polymer composition, the polymer composition comprising:
- a) a polyoxymethylene polymer comprising a polyoxymethylene copolymer containing oxymethyelene units and comonomer units, the proportion of comonomer units based on the proportion of oxymethylene units being between about 0.001 mol % and about 0.05 mol %;
- b) at least one coupling agent;
- and
- c) at least one reinforcing fiber, and wherein the polymer composition has a heat deflection temperature of greater than 165° C.
