Ethylene propylene rubber is an elastomer prepared from ethylene and propylene monomers (ethylene propylene copolymer) and at times with an amount of a third (diene) monomer (ethylene propylene diene terpolymers). Ethylene propylene rubber has a temperature range of -50°C to +120°C (-60°F to +250°F).
EPDM has a great acceptance in the sealing world because of its excellent resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight (UV). These compounds also withstand the effect of brake fluids and other phosphate ester-based hydraulic fluids.
