Title:
INTERIOR AUTOMOTIVE COMPONENT CONSTITUTED OF POLYACETAL RESIN
Document Type and Number:
WIPO Patent Application WO/2021/059608
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an interior automotive component obtained using a specific polyacetal resin composition which is stably inhibited from causing mold deposits during high-temperature molding and which can give molded articles that are extremely highly inhibited from generating formaldehyde, are prevented from suffering the oozing of a component therefrom, and retain a satisfactory appearance. The purpose of the present invention has been achieved with an interior automotive component obtained using a polyacetal resin composition which comprises (A) 100 parts by mass of a polyacetal polymer, (B) 0.03-0.30 parts by mass of a hindered phenolic antioxidant, (C) 0.01-0.50 parts by mass of an aliphatic carboxylic acid hydrazide, (D) 0.001-0.50 parts by mass of a hydantoin compound having two hydrazinocarbonylalkyl groups, and (E) 0.001-0.30 parts by mass of an alkaline-earth metal salt of an aliphatic carboxylic acid, the sum of the components (C) and (D) being 0.03-0.55 parts by mass per 100 parts by mass of the polyacetal polymer (A).
