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 |
