Definition and Properties of Automotive Rubber Seals

Today we are going to learn about the rubber seal strips of cars.

Silicone rubber wire seal is formed by microwave vulcanization at one time, with a smooth and beautiful surface, good elasticity and resistance to compression deformation, weather resistance, ozone resistance, chemical resistance and a wide range of use temperature (-40 ℃ ~ + 120 ℃) and other excellent performance, has been widely used in automotive doors, windows, curtain walls and other manufacturing industries. For products with different shapes, different materials, or requirements for cold resistance, heat resistance, foaming, solid body, and special properties, it can meet the needs of design and use.

Automotive connector sealing characteristics:

1. Auto connector seal has excellent weather resistance, weather resistance refers to the ability to resist severe cold, hot, dry and humid for a long time. Extend the life of the sealant.

2. Heat aging resistance means strong air aging resistance. It can be used at 100-120 ℃ for a long time, and it can maintain effective physical properties at 140-150 ℃ for a long time. It can withstand high temperature of 230-260 ℃ for a short time. To the time-delay effect; coupled with the use of a special formula, the EPDM rubber has a similar feel at -50 ° C to 150 ° C, which has created a highly efficient work performance for production site installation.

3. Because of the excellent ozone resistance of automotive rubber seal, and known as "crack-free rubber", especially used in different atmospheric index, completely exposed to the air on all kinds of urban buildings, will show the superiority of its products.

4. The anti-ultraviolet radiation provides the residents of high-rise buildings with a protective effect on the environment;Can withstand 60~150KV voltage, corona resistance, resistance to electrical cracking, resistance to electric arc, also very good.Low temperature elasticity, the temperature when the tensile capacity reaches 100MPa is -58.8℃.

5, due to the excellent physical and mechanical properties, thus has often been used in the manufacture of aircraft, cars, trains, buses, ships, high and low voltage switchgear, glass curtain wall, aluminium alloy window heat sealing parts and diving products, high pressure steam hose, tunnels, the viaduct connectors waterproof parts and other industrial and agricultural seal parts.
