Characteristics of EPDM sealing strip

2021-07-29


EPDM sealing strip is EPDM sealing strip, which is formed at one time by microwave vulcanization process. The surface is smooth and beautiful, with good elasticity and compression deformation resistance, weather resistance, ozone resistance, chemical resistance, and fire resistance. And a wide temperature range (-50 ℃ ~ 150 ℃) and other excellent performance. Has been widely used in automotive doors and windows curtain wall and other manufacturing industries. For products with different shapes, different materials or cold resistance, heat resistance, foaming, entity and special performance requirements, EPDM sealing strips can meet the needs of design and use. Here to understand the characteristics of EPDM sealing strip.

1, EPDM sealing strip has good weather resistance, weather resistance refers to the long-term resistance to cold, hot, dry and wet, has excellent corrosion resistance to rain and snow erosion, can extend the service life of the rubber strip.

2, heat aging refers to the heat resistant air aging strong. EPDM sealing strip can be used for a long time at 100-120 ℃, and can maintain effective physical properties for a long time at 140-150 ℃. It can withstand high temperatures of 230-260°C in a short time. Can be used for urban construction accidents. Coupled with the use of a special formula, the EPDM sealing strip feels similar at a temperature of -50°C to 150°C, creating a higher working performance for production site installation.

Because the EPDM sealing strip has excellent ozone resistance, it is also called "crack-free rubber". It is especially suitable for urban buildings with different atmospheric indicators and completely exposed to the air. It will demonstrate the superiority of its products.

4. Anti-ultraviolet radiation, providing environmental protection for residents of high-rise buildings; Voltage resistance 60 ~ 150KV, corona resistance, electrical cracking resistance, arc resistance, low temperature elasticity is also very good, EPDM sealing strip tensile capacity of 100MPa when the temperature is -58.8 ℃.

5. Because of its excellent physical and mechanical properties, EPDM sealing strips are commonly used in the manufacture of airplanes, automobiles, trains, buses, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat insulation window seals and diving products, high pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural seals.
