Performance characteristics of sealing silicone strip

Time of issue: : 2020-07--11 Number of views : 0
1. Weather resistance Weather resistance refers to the ability of long-term cold resistance, heat resistance, dry resistance and humidity resistance. It has excellent resistance to rain and snow erosion and prolongs the service life of the sealing strip. 2. Heat aging Heat aging refers to the strong aging of hot air. It can be used for a long time at 100-120°C, can maintain effective substances for a long time at 140-150°C, and can reach a high temperature of 230-260°C in a short time, which can delay urban construction accidents . 3. Ozone resistance has excellent ozone resistance, especially in urban buildings with different atmospheric indexes and completely exposed to the air, it will show the superiority of its products. 4. Anti-ultraviolet radiation Anti-ultraviolet radiation provides a protective environment for high-rise buildings. It is resistant to 60~150KV voltage, corona, cracking, and arc resistance. At low temperatures, when the tensile capacity reaches 100MPa, the temperature is -58.8°C. 5. Physical and mechanical properties Due to its excellent physical and mechanical properties, it is often used in the manufacture of aircraft, automobiles, trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy insulation window seals and diving products, high pressure steam hoses, tunnels, and viaducts Joint waterproof parts and products.

Performance characteristics and applications of high temperature silica gel strips

Time of issue: : 2020-07--11 Number of views : 0
The high temperature silicone strip is better than the rubber seal of the ordinary silicone strip. It is made of high-temperature resistant organic silicon raw materials, and is mainly used for sealing objects in high-temperature operating environments. This kind of high temperature sealing strip is usually between -50 and 120 degrees, and can work for a long time, and its performance is stable and reliable. The common high temperature silicone strip is made of EPDM, elastomer (including TPV, TPE, TPR, SEBS) , Modified PVC, silica gel and other materials, extruded by microwave vulcanization and other foaming processes, the surface is smooth and beautiful, with good elasticity and resistance to compression deformation. High temperature silica gel strips are often used in: 1. Plastic-steel doors and windows, aluminum alloy doors and windows, wooden doors and windows and other architectural decoration doors and windows are mainly used for dustproof, insectproof, waterproof, soundproof, and sealing. 2. The door frame, side windows, front and rear windshield, engine cover and trunk cover play the role of waterproof, dustproof, sound insulation, temperature insulation, shock absorption and decoration. 3. The electrical cabinet is sealed, which has the characteristics of good sealing, waterproof, fireproof, insect-proof, windproof, light-proof, anti-collision and long service life.
