Commodity overview of EPDM sealing strips      

EPDM is a copolymer of ethylene, propylene and a few third monomers non-conjugated diene. It is named in the world: Ethyiene Propyene Diene Methyiene EPDM for short. It has outstanding anti-ultraviolet effect, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity, and other physical and mechanical functions. These advantages are not replaced by other materials such as PVC.

EPDM (EPDM) rubber strip is formed by microwave vulcanization process at one time. Its surface is smooth and beautiful, has good elasticity, anti-contraction deformation, weather aging resistance, ozone resistance, chemical resistance and wide application temperature scale (-50 ℃ ~ 150 ℃). It has been widely used in automobile doors, windows and curtain walls and other manufacturing industries. For products with different shapes, different raw materials, or cold resistance, heat resistance, foaming, solid body, and special functions, all can meet the needs of planning and application.

       Characteristics of EPDM sealing strip

1, EPDM sealing strip has excellent weather resistance, weather resistance refers to the ability to resist cold, hot, boring and humid for a long time, has excellent corrosion resistance to rain and snow water, and can completely extend the service life of the rubber strip.

2, heat aging refers to a strong heat-resistant air aging. It can be used at 100-120 ℃ for a long time, can also adhere to useful physical properties at 140-150 ℃ for an appropriately long period, can withstand high temperatures of 230-260 ℃ in a short time, and can have a delay effect in case of sudden accidents in urban construction. In addition, with the use of special formula, EPDM rubber feels around -50 ℃ to 150 ℃, which has invented high-efficiency operation performance for production site devices.

3, because EPDM has outstanding ozone resistance, also known as "crack-free rubber", especially used in different atmospheric index, completely exposed to the air of all kinds of urban buildings, but also show the superiority of its goods.

4. Anti-ultraviolet radiation provides environmental protection effect for high-rise building residents; it can withstand 60 ~ 150KV voltage, corona resistance, electric cracking resistance, arc resistance, and is also excellent. Low temperature elasticity, tensile ability to reach 100MPa when the temperature is -58. 8 DEG C.

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, glass curtain walls, aluminum alloy thermal broken windows, diving products, high pressure steam hoses, tunnel, viaduct joint number waterproof parts and other industrial and agricultural sealing parts.
