What are the key EPDM properties?
An EPDM seal, gasket or moulding is probably the most water resistant available. This excellent water resistance can be maintained to temperatures of up to 180°C in steam for peroxide cures. In addition EPDM seals provide:
- strong acid/alkali resistance
- excellent electrical insulation, compression set, and low temperature properties.
With proper use EPDM seals can last for long periods of time and act as a less expensive alternative to silicone. Trade names include Buna, Nordel and Keltan.
What is EPDM commonly used for?
EPDM is an extremely versatile material particularly suitable for outdoor use and has the dynamic properties between Natural and Silicone rubber. It has good resistance to most water based chemicals and to vegetable based hydraulic oils but poor resistance to mineral oils and di-ester based lubricants. The largest market for EPDMs is the automotive industry. Typical applications include hoses, window and door seals, gaskets, washers, belts and o-rings but at DP Seals we specialise in blending exactly the right material for your specific requirements.
