COMPOSITION OF POLYACETAL RESIN

摘要

PROBLEM TO BE SOLVED: To improve the mold releasability during molding processing to an ultrahigh level without substantially deteriorating mechanical characteristics of a polyacetal resin at all.

SOLUTION: A polyacetal resin composition is obtained by adding (B) 0.15-0.25 pt.wt. of at least one kind of an ethylene glycol difatty acid ester derived from a 10-20C higher fatty acid and (C) at least one kind of polyalkylene glycol having 3,000-20,000 number-average molecular weight in an amount of (1/2) to (3/4) that of pt.wt. of the ingredient (B) to (A) 100 pts.wt. of the polyacetal resin.
