POLYACETAL RESIN MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a polyacetal resin molding which has extremely high abrasion resistance, and can effectively prevent contamination of components in a sealed container under a high temperature and high humidity environment.SOLUTION: A polyacetal resin molding contains 100 pts.mass of (A) a polyacetal resin and 0.1-5 pts.mass of (B) a lubricant. A difference between the heights of the unevenness on the surface of the polyacetal resin molding before and after holding the polyacetal resin molding for 168 hours in an environment of a temperature of 85°C and a humidity of 85% is 200 nm or less.
