What’s the difference between EPDM & Other rubber?

Ethylene propylene rubber is easily produced and can be manufactured in many forms, including EPDM rubber flooring and adhesives. Thus, to choose the appropriate rubber it depends less on form and more on the rubber’s characteristics.

EPDM vs. SBR: Ethylene propylene rubber performs better than Styrene-Butadiene rubber (SBR) in nearly every way. EPDM has a lower compression set, a higher tensile strength, a better resistance to heat aging, and high weathering resistance. However, an SBR product will have a much better resistance to abrasions than an EPDM product would.

EPDM vs. NBR: Nitrile butadiene rubber (NBR) stands alone as the most oil- and fuel-resistant elastomer. It is also known for maintaining its stability in low temperatures. A sheet of NBR rubber can survive in temperatures as low as -22 degree Fahrenheit. On the other hand, EPDM sheet rubber lies on the opposite side of the spectrum and can operate at higher temperatures. The rubber is also more resistant to water swell and weathering elements.

EPDM vs. Natural Rubber: Natural rubber reigns as the most physically strong elastomer. It has an extremely low compression set, high tensile strength, incredible elongation, and a high resistance to abrasions. Most elastomers cannot hold a candle to natural rubber in such categories. While EPDM does have decent physical properties, they are not on the same level as natural rubber. However, EPDM rubber can brag about its resistances to UV and ozone, a quality that is natural rubber’s most glaring weakness.

EPDM vs. Silicone: Although UV and ozone resistances can be considered as the defining features of EPDM rubber, silicone is actually the synthetic elastomer with the highest resistances to such weathering elements. So, why would you choose an EPDM product over a silicone one? Silicone rubber is actually very easy to tear and has one of the weakest resistances to abrasive substances and conditions. On the other hand, EPDM is a UV-resistant rubber that has a great tensile strength and is moderately resistant to abrasions.

EPDM vs. Neoprene: As the all-purpose elastomer, neoprene matches EPDM stride for stride in properties such as compression set, resilience, and even ozone resistance. For the most part, these two products function in a very similar capacity. The one thing that gives EPDM rubber an edge is that it possesses a better level of water swell resistance and a larger operable temperature range than neoprene.
