EPDM – Ethylene Propylene Diene Rubber
Ethylene Propylene Diene Rubber (EPDM) is a copolymer manufactured from ethylene, propylene, and a small number of diene monomers. A small number of diene monomers form unsaturated groups pendant from the main saturated chain. These diene monomers provide cross-linking sites that allow EPDM to be vulcanised.
What Are The Advantages Of EPDM?
EPDM rubber has excellent heat, ozone and chemical resistance properties. In addition to this, EPDM also has good physical properties and is resistant to polar fluids.?
EPDM also has excellent resistance to low temperatures. Low-temperature properties require the polymer to be amorphous and low on ethylene. Good electrical properties require high ethylene to facilitate high doses of inert mineral fillers to give good electrical resistance.
What Are The Disadvantages Of EPDM?
EPDM is not suitable for exposure to petroleum-based fluids and di-ester lubricants.

What Are The Typical Applications Of EPDM?
Some of the typical applications where EPDM can be used include:
In addition, EPDM is available in Potable Water (WRAS) grades and a variety of ‘Food Quality’ mixes that are used in the food industry.
What Temperatures Can EPDM Operate Under?
The typical working temperature range of Ethylene Propylene Diene Rubber is -45°C to +125°C. Peroxide cured EPDM can withstand excursions of 150°C during service life.
