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 extreme cold, heat, dryness and humidity for a long time. It has excellent corrosion resistance to rain, snow and water, and can completely extend the service life of the rubber strip.

2. Heat aging resistance refers to the strong heat-resistant air aging resistance. It can be used at 100-120 ℃ for a long time, and at 140-150 ℃, it can also adhere to useful physical properties for an appropriate long period. It can withstand 230-260 ℃ high temperature in a short time, and can play a delay effect in case of unexpected urban construction; With special formula, EPDM rubber

Around the - 50 ℃ to 150 ℃ hand feel, this has created a high-efficiency operation performance for the production field device.

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

4. Anti ultraviolet radiation, providing environmental protection effect for high-rise buildings; It can withstand 60 ~ 150kV voltage, and has excellent corona resistance, electric crack resistance and arc resistance. It is elastic at low temperature, and the temperature when the tensile strength reaches 100MPa is - 58. 8℃。

5. Because of its excellent physical and mechanical functions, it is often used to make sealing parts and diving products of aircraft, automobiles, trains, buses, ships, high and low voltage switchgear, glass curtain walls, aluminum alloy heat insulation windows, high-pressure steam hoses, waterproof parts of tunnel and viaduct joints and other industrial and agricultural sealing parts.
