EPDM rubber is a terpolymer obtained by copolymerizing ethylene, propylene, and a third monomer represented by a diene. It can be crosslinked with sulfur and accelerants.
It is one of the most widely used rubbers in the industry due to its good mechanical properties and excellent resistance to atmospheric agents and ozone, both in static and dynamic applications, with a very interesting temperature range.
In formulations where peroxide is used as a crosslinking agent, it exhibits excellent C-set values and excellent resistance to applications where brake fluids or acidic condensates are involved.
Depending on the uses and needs, we offer different qualities of EPDM, each created to meet the different requirements of our customers:
Standard EPDM
Super EPDM
Extra EPDM
Applications:
Mechanical: Used for seals, O-rings, supports, and structural elements, both dynamic and static, where exposure to atmospheric agents and heat resistance are required.
Food: White food-grade version available on request.
Electrical: Its excellent electrical properties make it widely used for insulators and electrical applications.
Chemical: Good resistance to acids, but it is always recommended to check its compatibility using compatibility tables.
