The photovoltaic panel waterproof strip has good elasticity, good sealing, good corrosion resistance, and aging resistance (the product is exposed to the sun for three years without cracks). The EPDM sealing strip has excellent weather resistance and resistance. Ozone, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil filling and normal temperature fluidity. EPDM rubber products can be used for a long time at 120 ℃, and can be used temporarily or intermittently at 150-200 ℃. Adding suitable antioxidants can increase its service temperature. EPDM rubber cross-linked with peroxide can be used under harsh conditions. Under the condition of ozone concentration of 50pphm and stretching of 30%, the EPDM rubber sealing strip can last for more than 150h without cracking. , Weather resistance (use temperature range -40 ℃ -150 ℃), chemical resistance. After adding flame retardant, it has good fire resistance and flame retardancy. The product is processed and formed by microwave continuous vulcanization process at one time. The surface is smooth and beautiful, and the performance is more stable and not easy to deform. Uses: automobile 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, construction machinery, equipment, engineering construction, etc.
