Aflas® vs FKM (Viton®) for O-Rings and Seals
Aflas® (TFE/P, FEPM) | FKM (Viton®) |
Description | Both materials are well suited for use in the -10 to 205°C range. FKM has an advantage in lower temperatures and FKM 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, both materials are equally Poor. The differences in compression set resistence show that FKM has a significant advantage. Additionally, FKM has a significant advantage when considering wear resistance. Also, both materials are equally poor when comparing heat stability. Furthermore, both materials are equally Fair when comparing short term resilience. Finally, both materials are equally poor when evaluating differences in permeation resilience. Both materials are resistant to steam, ozone, solvents, strong acids, petroleum oils, brake fluids, acetone, halogenated hydrocarbons, di-ester lubricants, vacuum and most acids, with Aflas® having specific resistences to bases, hot amines, highly reactive organic chemicals, highly reactive inorganic chemicals, Hydrogen Sulfide (H2S), gamma-ray radiation, amines, ammonia, low molecular weight esters, low molecular weight ethers, skydrol fluids and steam <400ºF. FKM has specific resistence to compression set, broad spectrum chemical resistance, common fuels, mineral oils, vegetable oils, greases, aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, non-flammable hydraulic fluids, aging and silicone oils. |
