General Information on Elastomer Materials Frequently Used NBR (Buna"N", Nitrile) NBR is commonly referred to as a nitrile rubber and is the standard synthetic elastomer for accomplishing resilient-type seating or sealing in COVNA valves. It has excellent compatibility for most air, water, and light oil applications. It has a useful temperature range of 0°F to 180°F (-18°C to 82°C). EPDM (Ethylene Propylene) EPDM is selected for applications above the NBR temperature range, such as handling hot water and steam. Ethylene propylene has an extremely wide range of fluid compatibility, but has the distinct disadvantage that it cannot be used with petroleum-based fluids or contaminated fluids (such as lubricated air). It has a useful temperature range of -10°F to 212°F (-23°C to 100°C). FKM (Viton) FKM is a fluorocarbon elastomer primarily developed for handling such hydrocarbons as jet fuels, gasolines, solvents, etc., which normally cause detrimental swelling to NBR. FKM has a high temperature range similar to EPDM, but with the advantage of being somewhat more resistant to"dry heat."FKM has a wide range of chemical compatibility. It has a useful temperature range of 0°F to 248°F (-18°C to 120°C). PTFE (Teflon) PTFE is considered more a plastic than a resilient-type material. They're virtually unattacked by any fluid. Their temperature usage has ranged from discs for cryogenic valves to discs for steam valves. They're not easily fabricated and are known to have"cold flow"characteristics which may contribute to objectionable leakage, particularly on gases.
