Summary of advantages and characteristics of EPDM sealing strip
1. EPDM sealing strip has excellent weather resistance. Weather resistance refers to the ability to resist cold, heat, dryness and humidity for a long time. It has excellent corrosion resistance to rain and snow, which can extend the service life of the rubber strip.
2. Heat aging resistance refers to strong heat-resistant air aging resistance, which can be used for a long time at 100-120℃, and at 140-150℃, it can also maintain useful physical properties for a long time. It can withstand a high temperature of 230-260℃, which can delay the effect of sudden accidents in urban construction. Coupled with the use of a special formula, the EPDM rubber is in the vicinity of -50°C to 150°C, which provides high-efficiency operating performance for production site devices.
3. Because EPDM has outstanding ozone resistance, it is also called "crack-free rubber". Especially applied to various urban buildings with different atmospheric indexes and thoroughly exposed to the air, it will show the superiority of its products.
4. Anti-ultraviolet radiation provides environmental protection effects for residents in high-rise buildings. It can withstand voltage of 60～150KV, corona resistance, electric crack resistance, arc resistance, and it is also excellent, low temperature elasticity, and the temperature at which the stretch can reach 100MPa is -58.8℃.
5. Because of its excellent physical and mechanical functions, it is often used to make sealing parts for airplanes, automobiles, trains, buses, ships, high and low voltage switch cabinets, aluminum alloy thermal windows and diving products, glass curtain walls, tunnels, and viaduct joints No. waterproof parts and other industrial, high-pressure steam hoses, agricultural sealing parts, etc.
