A Brief Introduction to EPDM

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:
