Characteristics of EPDM sealing strip
2021-10-08
Features:
①. EPDM has excellent weather resistance, weather resistance refers to the long-term resistance to cold, hot, dry, wet ability, the erosion of rain and snow has excellent corrosion resistance, can extend the service life of the strip;
②. Heat aging resistance refers to a strong resistance to heat air aging. It can be used at 100-120 ℃ for a long time, can maintain effective physical properties at 140-150 ℃ for a long period of time, can withstand high temperatures of 230-260 ℃ in a short time, and can delay urban buildings in case of unexpected accidents. Coupled with the use of special formula, EPDM has similar hand feel at -50 ℃ to 150 ℃, which creates high-efficiency work performance for production site installation.
③. Because EPDM has excellent ozone resistance, it is also known as "crack-free rubber", especially when used in various urban buildings with different atmospheric indexes and completely exposed to the air, it will show the superiority of its products;
④. Anti-ultraviolet radiation, for high-rise building residents to provide environmental protection; can withstand 60 ~ 150KV voltage, corona resistance, electric cracking resistance, arc resistance, is also very good. Low-temperature elasticity, the temperature at which the tensile capacity reaches 100MPa is -58.8°C.
⑤. Because of its excellent physical and mechanical properties, it is often used in the manufacture of airplanes, cars, trains, buses, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy thermal window sealing parts and diving products, high pressure steam hoses, tunnels, Waterproof parts such as viaduct joints and other industrial and agricultural sealing parts.
