EPDM Rubber Compound for O-RING

This EPDM Rubber Compound for O-RING produced by our Xiamen SLD Rubber factory is a compound rubber based on ethylene propylene diene monomer (EPDM), specifically designed for the diverse environmental challenges faced by O-rings in static and dynamic sealing. Its core value lies in "its outstanding weather resistance, ozone resistance, high-temperature resistance and chemical resistance, especially its excellent performance in water, steam and various polar solvents, ensuring that the sealing system does not age or leak during long-term use.

Structure

The structure of this O-RING EPDM Rubber Compound produced by us is an enhanced protective formulation system for achieving all-round environmental tolerance. It is based on highly saturated EPDM rubber, and its molecular main chain has no double bonds, which fundamentally determines its excellent weather resistance and aging resistance. The formula incorporates highly efficient reinforcing agents and a dedicated protective system to further enhance its heat resistance and resistance to specific chemicals.

Product application

This O-RING EPDM Compound is the "core material" in all fields that have high requirements for environmental adaptability and sealing reliability. It is widely used in various sealing parts in the automotive industry (such as radiators and air conditioning pipelines), window and door sealing strips and joint sealing in the construction industry, as well as O-rings in hydraulic systems, water treatment equipment and chemical pipelines in the industrial field.
