Ethylene Propylene Diene Monomers (EPDM)

Recognised for its high density and durability, this synthetic rubber is made up of ethylene and propylene.

What is EPDM?

The ethylene and propylene materials making up EPDM originate from oil and natural gas.  Its combined form is classified as a terpolymer where a diene monomer is added to these two compounds.  EPDM uses a sulphur cure system.

A typical service temperature for this material would be a range between -65º F and 300º F.

This material offers very good resistance to aging caused by weather, ozone, exposure to UV, water and heat.  It is also excellent at resisting phosphate ester base hydraulic fluids, dilute acids and for use as electrical insulation.

Applications

This material is able to maintain performance in extremes of temperature with a shrewd resistance to weathering and oxidisation. It can be widely used in both static and dynamic applications.

It is therefore excellent for outdoor use and an industry favourite for rubber roofing as well as rubber gaskets and seals.

Other applications include auto parts, auto brake systems, electrical insulation, dust covers, weather stripping and conveyor belts.
