EPR is a great material to be used in many different fields, especially when it comes to commercial aircraft. It offers great ozone, water, steam, acid, and base resistance. However, it lacks in petroleum sealing. Temperature ranges -65ºF to 300ºF. Ethylene Propylene carries a special resistance to Skydrol® fluids which are commonly used in commercial aircraft hydraulic systems. Ethylene Propylene offers great resistance for ozone, water, steam, acids, and alkalies. This material is not great with petroleum sealing.



Temperature Range


EPDM has one of the best temperature ranges in the world of elastomers. Capable of withstanding arctic cold temperatures of -65ºF to a super hot +300ºF. This wide range of temperatures makes this material great for industrial applications in freezers. Storage areas that often change temperatures, and much more.

Chemical Resistance

EDPM  has great resistance to steam, sodium hydroxide, diluted acids, detergents, and other base-heavy chemicals. This material is not great against any petroleum-based oil or gases, fossil fuels, or lubricants. This being said, we do not recommend EDPM for any petrochemical applications. If you are in need of any petroleum-chemical we do recommend using Viton or Nitrile based sealing materials.




One major disadvantage with EPDM is its poor resistance to most petroleum-based fuels. oils and other non-polar solvents. This being said we cannot recommend this material for any petroleum-chemical application. If you are looking for a great material for use with oil and other petroleum-based products, Viton or Nitrile would offer superior resistance.
