Abstract
Tenacity of a high-molecular polyacetal resin is improved and stress relaxation thereof is also made to easily take place whereby there is provided a polyacetal resin composition in which a creep rupture life (creep characteristic) of polyacetal resin in a metal insert molding, etc. is significantly improved. (A) polyacetal resin having a melt index of 3.0 or less is compounded with (B) 0.05 to 3.0% by weight (in the composition) of silicone oil, (C) 0.1 to 5.0% by weight (in the composition) of elastomer and (D) 0.1 to 5.0% by weight (in the composition) of ultrahigh-molecular weight polyethylene.
Claims8
A polyacetal resin composition comprising:
- (A) polyacetal resin having a melt index of 3.0 or less,
- (B) 0.05 to 3.0% by weight per the composition of silicone oil,
- (C) 0.1 to 5.0% by weight per the composition of an elastomer and
- (D) 0.1 to 5.0% by weight per the composition of ultrahigh-molecular weight polyethylene.
