摘　　要：通过动态热老化实验、静态热老化实验、转矩流变实验及刚果红实验对HWG系列有机热稳定剂与国内外同等牌号的稳定剂进行了研究,发现HWG系列有机热稳定剂具有优良的热稳定性能及加工流变性能,能满足聚氯乙烯(PVC)各类软硬制品的加工要求。In this paper, thermal stability of 5 kinds of HWG organic composite stabilizers were evaluated with the similar products in home and abroad by dynamic ageing tests, static ageing test, rheology and Congo red tests. The results showed that HWG organic heat stabilizers provide much more excellent thermal stability and rheological properties, they could meet the needs to process all kinds of rigid and soft PVC products.
