Abstract:
A polyacetal resin composition comprises a polyacetal resin having a trioxane content of not more than 100 ppm (preferably not more than 50 ppm, and more preferably not more than 10 ppm) and at least one stabilizer selected from the group consisting of an antioxidant, a formaldehyde emission inhibitor, a processing stabilizer and a heat stabilizer. The polyacetal resin may be a polyacetal resin (particularly a polyacetal copolymer) in which the trioxane amount is reduced by a solvent treatment and/or a heat treatment. Moreover, the polyacetal resin composition may further contain at least one additive selected from the group consisting of a weather(light)-resistantstabilizer, an impact resistance improver, a gloss control agent, a sliding improver, a coloring agent, and a filler. Such a polyacetal resin composition can reduce the amount of trioxane elution and/or the amount of a volatile organic compound from a molded product thereof.
