Document Type and Number:
WIPO Patent Application WO/2022/270184
Kind Code:
A1
Abstract:
A polyacetal resin composition which contains, per 100 parts by mass of (A) a linear polyacetal copolymer that has a specific MFR and is mainly composed of an oxymethylene unit, while containing an oxyalkylene unit that serves as a comonomer unit at a predetermined ratio, 1 to 10 parts by mass of (B) a specific polyacetal copolymer that has a branched or crosslinked structure, 0.5 to 10 parts by mass of (C) a specific modified olefin polymer, 0.01 to 5 parts by mass of (D) a specific alkylene glycol polymer, 0.1 to 20 parts by mass of (E) a specific calcium carbonate, 0.1 to 10 parts by mass of a partial ester of a polyhydric alcohol having a functionality of 2 to 4, and 0.1 to 10 parts by mass of (G) an alpha olefin oligomer.
