摘要
对两种稀土复合热稳定剂在ＰＶＣ中应用的热稳定性能进行测试和分析，研究结果表明稀土复合效稳定剂的热稳定性能优于目前普遍采用的铅盐或金属皂类混合热稳定剂。
This paper deals with the test and analysis on the application of heat stabilizty of the two kinds of rare earth complex heat stabilizer using in PVC. The experiment shows that the heat stability of rare earth complex heat stabilizer is better than the conventional stabilizer at present.
