Document Type and Number:
Japanese Patent JP4764170
Kind Code:
B2
Abstract:
A polyacetal resin composition comprises a polyacetal resin, and a polycyclic aromatic carboxylic acid hydrazide or a polycyclic aromatic carboxylic acid hydrazide having a substituent. The proportion of the polycyclic aromatic carboxylic acid hydrazide may be about 0.001 to 20 parts by weight relative to 100 parts by weight of the polyacetal resin. The polyacetal resin composition may further comprise at least one member selected from an antioxidant, a heat stabilizer, a processing stabilizer, a weather (light)-resistant stabilizer, an impact resistance improver, a slip-improving agent, a coloring agent, and a filler. With the use of such a resin composition, stability of a polyacetal resin is improved, and formaldehyde emission is inhibited.
