Influence of Addition Levels of Secondary Curing Agent PDM and Sulfur on Properties of CM/EPDM Blends

Zhenxiang Xin

Abstract

The influence of addition levels of secondary curing agent PDM and sulfur for peroxide curing system on the properties of CM/EPDM blends was experimentally investigated.The results showed that,by using DCP/PDM curing system,the comprehensive properties of CM/EPDM blend were better when 3 phr DCP and 1.5~2 phr PDM were respectively used;by using DCP/sulfur curing system,the comprehensive properties of CM/EPDM blend were better when 3~4 phr DCP and 0.3~0.4 phr sulfur were respectively used.
