You may consider among Ethylene Propylene Diene Monomers (EPDM), Chloroprene Rubber Sponge (CR), Chloroprene Rubber / Styrene butadiene rubber (CR/SBR) and Styrene butadiene rubber / Ethylene Propylene Diene Monomers (SBR/EPDM).
◆ Physical strength: CR > CR/SBR > EPDM > SBR/EPDM
◆ Flame retardant：CR > CR/SBR > SBR/EPDM > EPDM
◆ Oil resistance：CR > CR/SBR > SBR/EPDM > EPDM
◆ Compression resistance：CR > CR/SBR > EPDM > SBR/EPDM
◆ Chemical resistance：EPDM > CR > SBR/EPDM > CR/SBR
◆ Weather resistance：EPDM > SBR/EPDM > CR > CR/SBR
