Introduction to the excellent performance and advantages of EPDM sealing strip

EPDM sealing strip, namely EPDM rubber strip, is formed at one time by microwave vulcanization process, with smooth and beautiful surface, good elasticity and compression deformation resistance, weather aging resistance, ozone resistance, chemical resistance and wide service temperature range (- 50 ℃ ~ + 150 ℃).

1. EPDM has excellent weather resistance and weather resistance, which means it has the ability to resist severe cold, hot, dry and humid for a long time, has excellent corrosion resistance to the erosion of rain, snow and water, and can completely prolong the service life of the adhesive strip;

2. Because EPDM has excellent ozone resistance, it is also known as "crack free rubber". Especially when it is used in various urban buildings with different atmospheric indexes and completely in the air, it will show the advantages of its products;

3. Anti ultraviolet radiation provides environmental protection for residents of high-rise buildings; It can withstand 60 ~ 150kV voltage, corona resistance, electric cracking resistance and arc resistance. Low temperature elasticity, and the temperature when the tensile capacity reaches 100MPa is - 58.8 ℃.

4. Due to its excellent physical and mechanical properties, it is often used to manufacture sealing parts of aircraft, cars, trains, buses, ships, high and low voltage switchgear, glass curtain wall, aluminum alloy heat break window, diving products, high-pressure steam hose, tunnel, viaduct joint and other waterproof parts and other industrial and agricultural sealing parts.

5. Heat aging resistance refers to strong heat-resistant air aging resistance. It can be used at 100-120 ℃ for a long time, and can maintain effective physical properties at 140-150 ℃ for a long time. It can withstand 230-260 ℃ high temperature in a short time, which can delay the occurrence of sudden accidents in urban buildings; With the use of special formula, EPDM feels similar at - 50 ℃ to 150 ℃, which creates high-efficiency work performance for production site installation.
