Wear-resistant polyoxymethylene resin composition and method for making same

摘要

The present invention provides a polyoxymethylene resin composition which is excellent in wear resistance and is suitable as materials for various sliding parts. The composition comprises (A) 65-98.8% by weight of a polyoxymethylene resin, (B) 0.2-5.0% by weight of a polyfunctional isocyanate compound, (C) 0.5-20% by weight of an olefin polymer containing 30% by weight or more of ethylene and a functional group containing an active hydrogen, and (D) 0.2-10% by weight of polyethylene.
