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 250⁰F is present)
