DOW CHEMICAL ET378 Resistant O-Rings and Seals

Dow Chemical 5004 is also known as ethylene-propylene-diene terpolymer (EPDM) and is a synthetic rubber used in a variety of applications such as roofing membranes, hoses, gaskets, electrical insulation, and automotive parts. Common uses for EPDM include roofing applications, pipe insulation, hoses, gaskets, seals, and automotive parts.

EPDM rubber may be susceptible to failure when exposed to certain chemicals, such as ozone, UV radiation, certain oils, and certain acids. Ozone and UV radiation can cause cracking, hardening, and embrittlement of EPDM rubber. Oils and acids can cause swelling, softening, and discoloration of the rubber, and may lead to premature failure.
