Abstract

The effects of the type and addition level of accelerators on the performances of EPDM sponge were investigated.The results showed that,under certain blowing system,the curing rate had significant influence on the structure and properties of EPDM sponge.It was found that,by using the AC/OBSH/urea blowing system,and the curing system composed of 1.2 phr sulfur,1 phr accelerator TMTD,0.8 phr accelerator M,1.2 phr accelerator PZ,and 1.5 phr accelerator BZ,the EPDM sponge possessed a well-distributed cellular structure and had good performance.
