POLYACETAL RESIN

摘要

PROBLEM TO BE SOLVED: To improve high-temperature resistant creep characteristics at a high level without substantially deteriorating molding processing characteristics of a polyacetal resin at all. SOLUTION: The polyacetal resin has 10-100 wt.ppm of the total amount of volatile organic compounds except formaldehyde released when heated at 90°C for 30 min. The polyacetal resin comprises a sterically hindered phenol as an antioxidant, a compound and/or a polymer containing a formaldehyde-reactive nitrogen as a heat stabilizer and a formic acid scavenger.
