EPDM Extrusions & Molded Products


EPDM Extrusions

EPDM rubber, a polymer composed of ethylene propylene diene monomer, is the premier weather resistant synthetic elastomer. EPDM rubber has excellent heat, ozone, UV, aging, and weathering resistance. EPDM rubber also exhibits excellent electrical insulation, good compression set and low-temperature properties. EPDM rubber is resistant to a wide range of fluids including water, ethylene glycol (anti-freeze) and offers good resistance to most water-based chemicals and vegetable-based hydraulic fluids. EPDM is also resistant to many mild acids, liquid fertilizers and synthetic brake fluids.

EPDM can be fabricated in a variety of ways, which include custom molded and extruded parts. The long-term lifespan allows for fewer replacement parts, saving money in the long run.

KEY CHARACTERISTICS:

  • Excellent resistance to ozone, UV, steam, water, and oxygen
  • Excellent resistance to acids, alkali, and ketones
  • Excellent heat resistance and aging
  • Low temperature usage: -20°F to -60°F (-29°C to -51°C)
  • High temperature usage: Up to 350˚F (UP to 177˚C)
  • Tensile Range: 500-2500 P.S.I.
  • Elongation: 600% Maximum
  • Durometer (Hardness) Range: 30-90 Shore A
  • Good electrical insulation properties
  • Low electrical conductivity
  • Adhesion to metals: Fair to Good
  • Solvent resistance: Poor
  • Oil resistance: Poor

The largest market for EPDMs is the automotive industry. Typical applications include radiator and heater hoses, window and door seals, O-rings and gaskets, accumulator bladders, wire and cable connectors, and weather stripping.

Ethylene Propylene has gained wide seal industry acceptance for its excellent ozone and chemical resistance properties and is compatible with many polar fluids that adversely affect other elastomers. EPDM compounds are typically developed with a sulfur or peroxide cure system. Peroxide-cured compounds are suitable for higher temperature exposure and typically have improved compression set performance.
