EPDM O Rings

EPDM O Rings have a working temperature range -45 to +130 degrees C.

EPDM O Rings have good resistance to hot water, steam, detergents, caustic potash solutions and silicone oils and greases and can be used with some diluted acids and chemicals. EPDM should not be used with most mineral based products.

Our range includes British Standard (BS1806), British Metric (BS4518) and German Metric (DIN3771). We also stock materials such as Nitrile, Viton, Silicone, EP, Neoprene, Polyurethane and many more.

EPDM rubber or Ethylene Propylene Diene Monomer is a type of synthetic rubber and is an elastomer characterized by a wide range of applications. The M refers to its classification in ASTM standard D-1418; the M class includes rubbers having a saturated chain of the polymethylene type. Dienes currently used in the manufacture of EPDM rubbers are dicyclopentadiene (DCPD), ethylidene norbornene (ENB), and vinyl norbornene (VNB). EPDM rubber is closely related to ethylene propylene rubber which is a copolymer of ethylene and propylene, whereas EPDM rubber is a terpolymer of ethylene, propylene and a diene component.

The main properties of EPDM are its outstanding heat, ozone, and weather resistance. The resistance to is also good. It has excellent electrical insulating properties. and also has good resistance to ketones, ordinary diluted acids, and alkaline.
