Release time:
2021-01-26
What are the characteristics of EPDM sealing strip? Many users who do not understand are still worried about the use of the product. EPDM sealing strip is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diene. EPDM sealing strip has excellent UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity and other physical and mechanical properties. These advantages are irreplaceable by other materials such as PVC.

These advantages are irreplaceable by other materials such as PVC.
EPDM sealing strip is formed by microwave vulcanization process at one time, with smooth and beautiful surface, good elasticity and compression deformation resistance, weather aging resistance, ozone resistance, chemical resistance and wide operating temperature range (-50 ℃ ~ 150 ℃), etc. Excellent performance, has been widely used in manufacturing industries such as automobile doors, windows and curtain walls. For different shapes, different materials, or cold resistance, heat resistance, foaming, solid body, as well as products with special performance requirements, can meet the needs of design and use.
1. It has excellent weather resistance. Weather resistance refers to the ability to resist severe 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 refers to a strong heat-resistant 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 play a role in delaying accidents in urban buildings. Coupled with the use of special formula, EPDM sealing strip has similar hand feel at -50 ℃ to 150 ℃, which creates high-efficiency work performance for production site installation.
3. It has excellent ozone resistance and 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, EPDM sealing strip anti-ultraviolet radiation, for high-rise building residents to provide the protection of the environment, 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. It has excellent physical and mechanical properties, so 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, Waterproof parts such as tunnels, viaduct joints and other industrial and agricultural sealing parts.
