A polyacetal resin composition comprises a polyacetal resin and a hetero atom-containing aliphatic carboxylic acid hydrazide. The proportion of the hetero atom-containing aliphatic 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 the group consisting of an antioxidant, a heat stabilizer, a processing stabilizer, a weather (light)-resistant stabilizer, an impact resistance improver, a gloss control agent, an agent for improving sliding property, a coloring agent, and a filler. Such a resin composition improves stability of the polyacetal resin and inhibits formaldehyde emission.
聚缩醛树脂组合物由聚缩醛树脂和含杂原子的脂肪族羧酸酰肼组成。相对于 100 重量份的聚缩醛树脂,含杂原子的脂肪族羧酸酰肼的比例可为 0.001 至 20 重量份。聚缩醛树脂组合物可进一步包含至少一种选自以下组别的成员:抗氧化剂、热稳定剂、加工稳定剂、耐候(光)稳定剂、抗冲击性改进剂、光泽控制剂、改善滑动性能剂、着色剂和填料。这种树脂组合物可以提高聚缩醛树脂的稳定性,并抑制甲醛释放。
