US Patent 9062183 Fiber reinforced polyoxymethylene composition with improved thermal properties

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.
