EPDM Properties

Full Name Ethylene Propylene Diene Monomer
Also Known As EPDM rubber
Max Temperature 150°C (302°F) continuous
Min Temperature -50°C (-58°F)

Common Applications

Water Systems

Seals, gaskets, and hoses for potable water systems

Outdoor Seals

Window seals, roofing membranes, automotive weatherstrips

Steam Systems

Steam hoses, autoclave seals, food processing

Not Recommended For

EPDM may degrade when exposed to:

  • Petroleum oils and fuels
  • Hydrocarbon solvents
  • Mineral oils and greases
  • Turpentine and naphtha

Tip: For oil and fuel resistance, use NBR instead. For extreme chemicals, consider Viton (FKM).
