Document Type and Number:
WIPO Patent Application WO/2019/167463
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a polyacetal resin composition which can give molded articles extremely highly inhibited from emitting formaldehyde and which is stably inhibited from giving mold deposits at the time of production. The purpose of the present invention is accomplished with a polyacetal resin composition which comprises (A) 100 parts by mass of a polyacetal polymer, (B) 0.01-3 parts by mass of a hindered-phenol antioxidant, (C) 0.01-1 part by mass of a hydrazide compound, (D) 0.01-0.5 parts by mass of a calcium salt of a fatty acid, and (E) 0.01-1.0 part by mass of at least one fatty acid full ester compound selected from among compounds which are fatty acid full esters of tri- to hexahydric alcohols and have an acid value of 4 or less.
