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.


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-Indexcom.


Layering

RoofHelpcom 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-Groupcom states that natural rubber can degrade when attacked by ozone.

EPDM has very high durability with ozone. 


Resilience

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


Value

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


Temperature

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