The EPDM sealing strip for curtain wall expansion joints and the rubber strip for curtain wall organ panel expansion joints have good elasticity, sealing performance, corrosion resistance, and aging resistance (the product will not crack after being exposed to sunlight for three years). The EPDM sealing strip has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, steam resistance, color stability, electrical performance, oil charging, and room temperature fluidity. EPDM rubber products can be used for a long time at 120 ℃, and can be used briefly or intermittently at 150-200 ℃. Adding suitable anti-aging agents can increase their usage temperature. EPDM rubber crosslinked with peroxides can be used under harsh conditions. Under the conditions of an ozone concentration of 50pphm and a tensile strength of 30%, the EPDM rubber sealing strip can withstand more than 150 hours without cracking., Weather resistance (operating temperature range -40 ℃ -150 ℃), chemical resistance. After adding flame retardants, the product has good fire resistance and flame retardancy. It is processed and formed in one go using microwave continuous vulcanization technology, with a smooth and beautiful surface and more stable performance that is not easily deformed. Usage: Automotive doors and windows, plastic steel doors and windows, aluminum alloy doors and windows, curtain wall doors and windows, containers, cabinets, electrical cabinets, furniture, wooden doors and windows, engineering machinery, equipment, engineering construction, etc
