FKM (Viton®) vs EPDM (EPR) for O-Rings and Seals

FKM (Viton®)

EPDM (EP, EPR, Ethylene-Propylene Rubber)

Description
Both materials are well suited for use in the -30 to 150°C range. FKM has an advantage in lower temperatures and EPDM has an advantage in higher temperatures. Marco offers specific compound formulations extending these ranges even futher as can be seen in the following compound comparison chart. When comparing these materials with respect to electrical current resistance, EPDM has a slight advantage. The differences in compression set resistence show that FKM has a slight advantage. Additionally, FKM has a slight advantage when considering wear resistance. Also, FKM has a slight advantage when comparing heat stability. Furthermore, both materials are equally Fair when comparing short term resilience. Finally, FKM has a slight advantage when evaluating differences in permeation resilience. Both materials are resistant to steam, greases, silicone oils and brake fluids, with FKM having specific resistences to ozone, solvents, compression set, broad spectrum chemical resistance, common fuels, mineral oils, vegetable oils, aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, non-flammable hydraulic fluids, aging, strong acids, petroleum oils, acetone, halogenated hydrocarbons, di-ester lubricants, vacuum and most acids. EPDM has specific resistence to acids, bases, phosphate ester hydraulic fluids, weathering and sunlight, glycol brake fluids (DOT 3, 4, 5.1), cleaning agents, ketones, some acids and steam <300ºF.
