Application of black EPDM O-ring in water and wastewater system
Ethylene propylene rubber (EPR) is a copolymer of ethylene and propylene. In addition, EPDM rubber is a terpolymer of ethylene and propylene with a small amount of third monomer (usually diene), which can be vulcanized with sulfur. EPDM O-rings are suitable for many industries, from automobile assembly to water purification systems.
