Rubber products have a wide variety of uses. From home roofing to waterproofing and sealing of RVs, understanding the difference between EPDM rubber and natural rubber helps consumers to make an informed choice.

Both EPDM and natural rubber have numerous uses.

What is EPDM

EPDM Coatings, provider of EPDM products, describes EPDM rubber as a synthetic rubber polymer developed in the 1960s. EPDM is an abbreviation for ethylene propylene diene monomer, according to Construction-Index.com.


RoofHelp.com reports that EPDM roofs are single-ply, as opposed to other products that require multiple plies laminated together.

UV and Ozone

North Shore RV reports that EPDM doesn’t require maintenance with products to protect it from ultraviolet light, like natural rubber does. Rubber-Group.com states that natural rubber can degrade when attacked by ozone. EPDM has very high durability with ozone.


According to AcmeRubber.com, EPDM rubber isn’t as resilient as natural rubber. Unlike natural rubber, EPDM should not be used with petroleum products.


EPDM rubber offers the same color stability and durability in heat as natural rubber but at a lower price.


EPDM is good for use in high temperature settings. Natural rubber is better in lower temperatures.
