摘要: A polyacetal resin composition which comprises about 100 parts by weight of a having residual fluorine concentration not more than 13 ppm and formaldehyde generated when the is heated at 230° C. for 30 minutes in nitrogen 500 ppm; from 0.01 to 3 an antioxidant; 0.001 5 basic substance. The above excellent long-term thermal aging resistance under high-temperature circumstances.
