Abstract

The influences of Ca/Zn composite stabilizer on the heat stability and weather ability of PVC were studied.The results showed that the thermal decomposition time determined by rheometer experiments could reflect the long-term heat stability of PVC during processing process,and when the dosage of Ca/Zn composite stabilizer was up to a value,its influence on the heat stability and weather ability was small.This research was helpful for choosing the dosage of stabilizer.
