EPDM Rubber Parts

Excellent oxidation and ozone resistance, heat resistance and aging resistance. With excellent vulcanization properties, EPDM is widely used in automotive parts, waterproof materials for construction, wire and cable sheaths, automotive seals and other fields.

What is EPDM rubber?

EPDM (Ethylene Propylene Diene Monomer), the main feature is its superior resistance to oxidation, ozone and corrosion. Among all the rubbers, EPDM has the lowest density which can absorb large amounts of fillers and oils with little effect on its properties, making it possible to make inexpensive rubber compounds. In addition, EPDM has been greatly improved in performance through modification, greatly expanding its application range.

Advantage and Benefit of EPDM

Aging resistance

Excellent weather resistance, ozone resistance, heat resistance, and UV resistance. Adding a suitable anti-aging agent can increase its service temperature, and the modified EPDM rubber can be used under harsh conditions.

Corrosion Resistance

Good resistance to many chemicals, however, EPDM is poor stability in mineral oils.

Steam and Water Resistant

Long-term use in super heated steam and hot water, little change in mechanical properties.

Low Electrical Conductivity

EPDM has excellent electrical insulation properties and corona resistance.

Applications of EPDM Rubber

Automotive: air hose, hydraulic brake system, weather stripping and seal, joint bellow;
HVAC: compressor grommet, silent block, panel gaskets and seal;
General Industrial: o ring and seal, grommets, hoses, dust boots, rollers.
