Research on experimental formula of EPDM 4045

The ethylene-propylene rubber(EPDM)4045 was estimated by evaluation methods of the SH/T 1743-2004 for Ethylene-Propylene-Diene rubber(EPDM)and the Q/SY JH F 104005—2003 for EPR.The limitations of the industry standard formula was confirmed.A new mixing formula was established through the experiments,and no product technical specifications were influenced.
