Title:
POLYACETAL RESIN COMPOSITION, AND SULFUR-CONTAINING FUEL CONTACT BODY INCLUDING MOLDED ARTICLE OF SAID POLYACETAL RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/201669
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a polyacetal resin composition that, when made into a molded article, makes it possible to inhibit deterioration due to exposure to sunlight at a portion that contacts a high sulfur fuel. This purpose of the present invention is achieved by a polyacetal resin composition comprising, at least: (A) 100 parts by mass of a polyacetal polymer; (B) 0.1-1.0 parts by mass of a hindered-phenol-based antioxidant; (C) 0.3-2.0 parts by mass of at least one substance selected from oxides of zinc and magnesium; (D) 0.5-3.0 parts by mass of polyalkylene glycol; (E) 0.1-1.5 parts by mass of a hindered amine compound; (F) 0.2-1.5 parts by mass of an ultraviolet absorbing agent; and (G) 0.01-1.0 mass of a fatty acid ester of a polyalcohol in which the esterification rate is not less than 80%.
