Product Name: EPDM O-rings are also known as ethylene propylene O-rings because of their chemical composition. The use of EPDM O-rings and seals is common in the automotive manufacturing industry that requires sealed braking systems. EPDM material is also compatible with heat in steam and water vapor, resistant to ozone, sunlight, and weathering, and has strong flexibility and chemical resistance at low temperatures.
Temperature range: For EPDM, the operating temperature can be designed to be -55 ° C to 125 ° C or up to 150 ° C (for peroxide curing systems).
