EPDM Terminology
Extrusion Dimensional Tolerance BS3734-1: 1997
• EPDM is a terpolymer of ethylene, propylene and small percentage of a nonconjugated diene. Diene provides
unsaturation in side chains pendent from the fully saturated backbone.

• Rubber grades with higher ethylene content can be more easily processed and more highly loaded with fillers and

• Peroxide-cured EPDM can be vulcanized by LCM line only, to comply with compression set properties as per DIN
7863.
• Peroxide-cured EPDM can deliver compression set performance for decades.
• Peroxide-cured EPDM are ideal for applications requiring ‘Good High Temperature Performance’ and ‘Low
Compression Set’, e.g. Architectural Sealing Products in harsh climate areas of the world.

Vulcanized Rubber Properties
Vulcanized EPDM have fair tensile strength over a wide hardness range and excellent resistance to ozone, weathering
and chemical attack. Furthermore, they exhibit very good electrical insulation properties.
• EPDM Vulcanizates are resistant to the following:
o Non petroleum–based automotive brake fluids
o Aryl and alkyl-aryl phosphate esters
o Hot water and steam, up to 200oC with peroxide cured vulcanizates
o Aqueous solutions of inorganic acids, alkalis and salts.
o Polyalkylene-glycol-based fluids.
o Alcohol, glycols, ketones (e.g. acetone, MEK) and low–molecular-weight esters (e.g. ethyl acetate)
o Silicone oils and greases.
Their resistance to animal and vegetable oils and fats is moderate, these substances can be tolerated in many static applications.
• EPDM Vulcanizates are not resistant to the following:
o Mineral-oil-based fluids and greases
o Synthetic hydrocarbon lubricants
o Organic-ester-based lubricants
o Hydrocarbon fuels
• Applications:
Ethylene-propylene rubbers are used for a wide range of products, including O-rings, gaskets, window and door
seals, wire & cable insulations, roller covers, conveyor belts, hoses and water-proofing sheets.
