Description:

Ethylene propylene diene monomer is also known as EPDM, the E stands for ethylene, P for propylene, D for Diene and M for monomer. The ethylene content is typically around 45% to 75% for the EPDM.

Advantages:

Can be used in water and steam (up to 300°F), glycol based brake fluids, silicone-based break fluids, many organic and inorganic acids, cleaning agents, sodium and potassium alkalis, phosphate ester based hydraulic fluids, silicone oil and grease, alcohols, ketones, esters and ozone.

Disadvantages:

Cannot be used with mineral oil products like oils, greases and fuels.
