Shelf Life:



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.


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.


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