Product overview of EPDM sealing strip

EPDM rubber is a copolymer of ethylene, propylene and a small number of third monomer non-conjugated diene. The world name is Ethyiene Propyene Diene Methyiene, abbreviated as EPDM. 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, as well as other physical and mechanical functions. These advantages cannot be replaced by other materials such as PVC.

EPDM rubber strips are formed by microwave vulcanization process at one time. The surface is smooth and beautiful, with good elasticity and resistance to shrinkage deformation, weather aging resistance, ozone resistance, chemical resistance and a wide range of application temperature (-50 ℃) ～150℃) and other excellent functions, which have been widely used in manufacturing industries such as automobile doors, windows and curtain walls. For products with different shapes, different raw materials, or cold resistance, heat resistance, foaming, solid body, and special functions, they can meet the needs of planning and application.

The characteristics of EPDM sealing strip

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

2. Heat aging resistance refers to strong heat-resistant air aging resistance. It can be used for a long time at 100-120℃, and at 140-150℃, it can also maintain useful physical properties for a suitable long period of time. It can withstand high temperature of 230-260℃ in a short time. It can be used for sudden accidents in urban construction. Play a delay effect; coupled with the use of a special formula, EPDM rubber feels near -50°C to 150°C, which invented high-efficiency operation performance for production site devices.

3. Because EPDM has outstanding ozone resistance, it is also called "crack-free rubber". It is especially used on various urban buildings that have different atmospheric indexes and are thoroughly exposed to the air. The superiority of the product.

4. Anti-ultraviolet radiation provides environmental protection effects for residents in high-rise buildings; it can withstand voltages of 60 to 150KV, and has excellent corona resistance, electric crack resistance, and arc resistance. Low temperature elasticity, the temperature at which the stretching can reach 100MPa is -58.8°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 windows, diving products, and high-pressure steam hoses. , Tunnel, viaduct joint number waterproof parts and other industrial and agricultural sealing parts.
