Ethylene Propylene O-Rings (EPDM) Special Compounds
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 Skydrol" and other phosphate ester-based hydraulic fluids. EPDM compounds are not recommended for gasoline, petroleum oil and grease, and hydrocarbon environments.
Special EPDM compounds have good resistance to steam or have specific certifications.
- EPDM Sulphur cured: inexpensive material for normal use, maximum temperature of +120°C (+250°F).
- EPDM Peroxide cured: for hot water, steam, alcohols, ketones, engine coolants, organic and inorganic acids and bases. Not resistant to mineral oils, greases and fuels. For maximum temperatures of +150°C (+300°F).
