EPDM Rubber Products & Applications

EPDM rubber (Ethylene Propylene Diene Monomer rubber) is a high-density synthetic rubber primarily used for outdoor applications like rubber roofing. It has dynamic and mechanical properties between natural rubber and synthetic rubber.

What is EPDM rubber used for?

EPDM rubber is an extremely versatile material that can be used in a variety of applications, from automotive products to HVAC parts. It also acts as a less expensive alternative to silicone and can last for long periods of time with proper use, saving you time and money.


  • Do not use EPDM rubber if continual contact with petroleum-based products is required.
  • EPDM rubber is not recommended for usage in food applications or those that are exposed to aromatic hydrocarbons.

Benefits & Advantages

Benefits of EPDM

  • Resistance to UV exposure, ozone, aging, weathering, and many chemicals - great for outdoor applications
  • Stability in high and low temperatures - a general purpose EPDM material can be used in an environment where the temperature range is from -20⁰F to +350⁰F (-29⁰C to 177⁰C).
  • Low electrical conductivity
  • Steam and water resistant
  • Used in the production of extruded rubber or molded rubber products
  • Properties allow it to be widely used and highly versatile, can be applied successfully in many situations
  • Used in the proper environment, the parts will work well and last long without breaking down, becoming brittle, etc. - saving you money on replacements
  • Less expensive than silicone, with similar properties (where heat below 250F is present)
