【Abstract】 Current research and application situation of lead-free stabilizer was introduced in briefly, while the characteristics, performance, as well as the stable mechanism of rare earth complex stabilizers used in UPVC products were investigated in detail. The examination reveled that the compound stabilizers (WWP) consisted of rare earth complex/calcium salt/ zinc complex are a novel series of high efficient, nontoxic and multi-functional "green" stabilizers.更多还原
