A Brief Introduction to EPDM
EPDM – also known as ethylene propylene diene monomer – is an extremely versatile material used in a variety of applications, from automotive products to HVAC parts. This type of rubber also acts as a less expensive alternative to silicone, as it can last for long periods of time with proper use.
You can get a general idea about the performance of EPDM in the below chart:
EPDM | Performance |
Operating Temperature | -50 to 140ºC |
Mechanical strength | Fair/Good |
Abrasion resistance | Fair |
Flex resistance | Fair |
Low Temp. Flexibility | Good/Excellent |
Ozone/Weather Resistance | Excellent |
Water Resistance | Excellent |
Impermeability to Gases | Good |
Oil Resistance | Poor |
Fuel Resistance | Poor |
Resistance to Dilute Acid | Excellent |
Resistance to Dilute Alkali | Good |
