EPDM Rubber

ASTM Designation: EPM, EPDM

Standard Colour: Black

Description: A co-polymer of ethylene and propylene monomers is known as EPM. When Diene monomers are combined to enable cross-linking, it is known as EPDM rubber.

Chemical Structure:
EPDM rubber Structure

Standard operating temperature Range: -50 OC to +150 OC

Hardness Range: 40 – 90 Shore A

  • Excellent weather, sunlight, ozone resistance
  • Excellent hot water/steam resistance
  • Good heat resistance
  • Excellent electrical insulation and dielectric properties
  • Good resistance to polar chemicals
  • Good low temperature properties
  • Poor resistance to mineral and hydrocarbon oil

  • Due to its outstanding weather, sunlight and ozone resistance, mostly used in outdoor rubber components
  • Automotive windshield, weather-strips, door-seal etc
  • Automotive radiator hose, coolant hose, radiator gasket etc
  • Cable insulation and jacketing
  • Window and architectural profiles in construction industry.
