Advantages of EPDM compounds in outdoor applications

Ethylene-Propylene-Diene-Monomer (EPDM) is a versatile polymer with outstanding ozone, weathering and aging resistance, making it ideal for use in outdoor applications.


EPDM polymers have good processability as well as good chemical and electrical properties. They exhibit very good physical properties even at very high filler loadings. These properties benefit a wide range of customers who use engineered elastomers in a broad range of applications.

EPDM polymers have a molecular backbone that is saturated in nature. Although side chain double bonds are present for crosslinking, they do not act as sites for polymer chain attack and degradation.

As such, EPDM compounds exhibit excellent environmental stability, with natural resistance to degradation from water, steam, UV and ozone. These properties are obtained without the use of antioxidants or waxes, which can stain or bloom and are generally required by most other polymers.

EPDM compounds can withstand a wide range of service temperatures. They are resistant to heat, and maintain flexibility even in cold temperatures. EPDM compounds have good impact resistance, compression set and resilience, for overall durability. They also exhibit resistance to alkalis, acids and oxygenated solvents.

The combined physical, thermal and chemical performance of EPDM parts allow them to last a long time in their application without breaking down—which in turn saves you money.

EPDM is a versatile, all-around polymer that can be used for many different applications.
