Abstract
The present invention provides a polyacetal resin composition comprising (A) a polyacetal resin and (B) zinc oxide, wherein the content of oxyalkylene constituent units other than an oxymethylene group in the polyacetal resin (A) is 0.1% by mass or more, and wherein the total surface area of the zinc oxide (B) in the polyacetal resin composition is 0.1 to 40 m2 per 100 g of the polyacetal resin (A); as well as an article molded therefrom.
Claims5
A polyacetal resin composition comprising:
- (A) a polyacetal resin and (B) zinc oxide, wherein the content of oxyalkylene constituent units other than an oxymethylene group in the polyacetal resin (A) is 0.1% by mass or more, wherein the total surface area of the zinc oxide (B) in the polyacetal resin composition is 0.1 to 40 m2 per 100 g of the polyacetal resin (A), and wherein the zinc oxide (B) has a BET specific surface area of 0.1 to 9 m2/g, and
- wherein the polyacetal resin composition contains 0.01 to 3.0 parts by mass of (E) at least one compound selected from the group consisting of a carbodiimide compound and an oxazoline compound, relative to 100 parts by mass of the polyacetal resin (A).
