Title:
POLYACETAL RESIN COMPOSITION AND SULFUR FUEL CONTACT BODY INCLUDING MOLDED ARTICLE OF POLYACETAL RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2014148625
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polyacetal resin composition which when formed into a molded article, provides the molded article capable of keeping an excellent surface by suppressing the occurrence of cracks even when high-sulfur fuel is contacted with the surface.SOLUTION: The polyacetal resin composition contains: (A) a polyacetal resin of 100 pts.wt.; (B) a hindered phenolic antioxidant of 0.1-1.0 pts.wt.; (C) an alkali earth metal oxide of 0.1-2.0 pts.wt.; (D) a formaldehyde reactive nitrogen compound of 0.01-0.3 pts.wt.; and (E) a phosphorus-based antioxidant of 0.01-0.5 pts.wt.; and preferably (F) a calcium organic acid salt of 0.1-1.0 pts.wt.. The molded article of the polyacetal resin composition can suppress a leak of high sulfur fuel since the number of the occurrence of cracks can be suppressed to any of "0", "1" and "2" in a figure even after the molded article is immersed in the high-sulfur fuel.
