POLYACETAL COMPOSITION

摘要

To provide a type of polyacetal composition appropriate for manufacturing sliding parts with excellent friction/wear characteristics. A type of polyacetal composition characterized by the fact that the composition contains 0.5-15 wt% (with respect to the total weight of the composition) of a polypropylene glycol elastomer crosslinked by sulfur as a copolymer made of 90-99.5 wt% of propylene glycol and 0.5-10 wt% of allyl glycidyl ether, or, the composition contains 0,5-10 wt% (with respect to the total weight of the composition) of a polypropylene glycol elastomer crosslinked by sulfur as a copolymer made of 90-99.5 wt% of propylene glycol and 0.5-10 wt% of allyl glycidyl ether, along with 0.5-10 wt% (with respect to the total weight of the composition) of polyalkylene glycol oil.
