<P>PROBLEM TO BE SOLVED: To provide a polyacetal resin composition excellent in mechanical properties such as tensile strength and tensile elongation and in discoloration resistance during long-term continuous molding. <P>SOLUTION: The polyacetal resin composition includes: 0.15-1 pts.mass of an aliphatic monohydric alcohol (II); 3-10 pts.mass of an ester (III) composed of an aliphatic monohydric alcohol and an aliphatic monovalent carboxylic acid; and 0.5-50 pts.mass of an inorganic filler (IV) based on 100 pts.mass of a polyacetal resin (I). A mass ratio ((III)/(II)) of the ester (III) composed of the aliphatic monohydric alcohol and the aliphatic monovalent carboxylic acid to the aliphatic monohydric alcohol (II) is 5-20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
