EPDM is the rubber that have properties of DOT3 brake oil resistance .The properties of our company’s EPDM are follows:

Hardness:70(Shore hardness)

Tensile strength: 18.3MPa

Ultimate elongation: 380%

Compression set: (test condition: 100℃,72h,type-B experimental model, press deformed 25%) 15%

DOT3 resistance test(120℃×72h)

Mass change rate: 0.3%

Volume change rate: 0.6%

The above properties of EPDM make the brake cups reliable and stable.
