1.稀土聚氯乙烯无毒稳定剂由于聚氯乙烯(PVC)树脂成型加工温度高于分解温度,在成型制品时需加入一种稳定剂,使其分解温度提高到成型加工温度以上,分解温度越高,其热稳定效果越好,成型越容易,传统使用的热稳定剂主要是铅盐和金属皂盐。这些热稳定剂有毒,而且加入量大,制品不透明。
1. Rare-earth PVC non-toxic stabilizer As polyvinyl chloride (PVC) resin molding temperature is higher than the decomposition temperature, the molding products need to add a stabilizer, the decomposition temperature increased above the molding temperature, the decomposition temperature The higher the thermal stability of the better, the easier the molding, the traditional thermal stabilizer is mainly lead salts and metal soap salts. These thermal stabilizers are toxic and they are added in large quantities, opaque to the product.
