2022-01-15
EPDM sealing strip is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diene, referred to as EPDM rubber. It has physical and mechanical properties such as heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity, which can not be replaced by other materials such as PVC.

EPDM sealing strip can be filled with a large amount of oil and filler, thereby reducing the cost of rubber products and making up for the high price of ethylene propylene rubber. For EPDM sealing strips with high Mooney value, the physical mechanical energy after high filling is not greatly reduced.
EPDM sealing strip performance characteristics:
1. Anti-aging:
EPDM sealing strip has good weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil and room temperature fluidity. EPDM rubber tape can be used for a long time under 120, and can be used temporarily or intermittently under 150-200. The temperature of use can be increased by adding appropriate antioxidants. Peroxide-crosslinked can be used under harsh conditions. Under the conditions of ozone concentration of 50pphm and tensile strength of 30%, EPDM rubber can reach more than 150 hours without cracking.
