A versatile, synthetic material that exhibits desirable working properties, good physical and chemical attack resistance properties.

Available in a range of products from solid rubbers, sponge and adhesives; EPDM is a unique and versatile material with many useful features. Used around the world in numerous applications and environments.

What is EPDM?

EPDM or Ethylene Propylene Diene Monomer (AA, BA, CA, DA) is a synthetic rubber. It’s primary components (ethylene and propylene) are derived from oil and natural gas; this material has a reputation as a tough, durable and abrasion resistant sealing rubber. It also has enhanced ozone and chemical resistant properties.

Where is EPDM used?

EPDM is used in a wide range of applications and environments. From our factory in Broadstairs, Silpro can supply EPDM in sheeting, extrusions and mouldings. It is widely used in roofing systems, pond liners, glazing seals and tapes. O-rings are also manufactured for static seals.
EPDM is used extensively in the automotive industry where seals are used for doors, windows and boots as well in the engine bay (cooling systems such as radiators, air conditioning).
It has a temperature range of -40°C to +150°C (intermittent). It is capable of resisting chemical attack from many organic and inorganic acids, alkalis and solvents including brake fluids (Dot 3 and 4).

Features/Benefits Of EPDM

Temperature range – -40°C to +150°C (intermittent)
Chemical resistance – EPDM is capable of resisting chemical attack from many organic and inorganic acids, alkalis and solvents including brake fluids (Dot 3 and 4).
Food contact – suitable for use with food and drink contact applications, meets FDA, WRAS and NSF approvals/certifications.

Limitations Of EPDM

Chemical Resistance – While EPDM is a fluorinated elastomeric compound it is not suitable for mineral oil contact, however materials such as silicone and fluorosilicone are.
