Rubber Seal Strip Obvious Progress

Rubber Seal Strip After more than 20 years of development, automotive sealing strip product structure and product design, production equipment and technology has made significant progress, most of the sealing strip extrusion line heating vulcanization method for microwave vulcanization and hot air vulcanization combination, but also the use of glass beads boiling bed vulcanization and vulcanizing tank heating vulcanization methods, in recent years, introduced the European high temperature and strong wind, Rubber Seal Strip multi-directional air heating vulcanized rubber sealing strip extrusion line.

Rubber sealing strip material base is EPDM rubber, in order to meet the different types and different parts of the installation requirements, automotive seals require the use of different properties of EPDM rubber mixing adhesive production. With the development of automobile industry, Rubber Seal Strip more and more new materials are used in automobile sealing strip, especially thermoplastic elastomer (TPE) as the advantage of automobile sealing strip is recognized by insiders, the thermoplastic elastomer materials used in automobile sealing strips are mainly polyolefin elastomers it has good abrasion resistance and small friction coefficient, and is used as the extruding material of automobile glass guide Groove sealing strip, and it can be made into the angle of automobile sealing strip. In addition, foam sponge TPE has been successfully developed abroad. has been widely used in automobile rubber seals, Rubber Seal Strip become the new trend of replacing sponge rubber to make automobile seals; In addition, TPE coloring process is simple and convenient, has often been used as automotive rubber seals outside the decorative materials, the current color TPE and color rubber on-line coextrusion coated rubber seal technology, several domestic automotive seal enterprises have been introduced.

In order to prevent the rubber seal and the body to open the fitting surface freeze adhesion, usually using silicone coating on the rubber sealing strip surface treatment; Rubber Seal Strip polyurethane coating on the rubber seal slip surface used to replace electrostatic flocking technology has also begun to be applied.

High-temperature rubber seal than ordinary silicone rubber sealing strip is better, is made of high-temperature-resistant silicone raw materials, mainly used in high-temperature operating environment of the goods sealed. This high-temperature rubber sealing strip generally 20 between the degree, Rubber Seal Strip and can be long-term work, stable and reliable performance. Common high-temperature seals are EPDM, elastomer (including TPV, TPE, TPR, SEBs), modified PVC, silica gel and other materials, the use of microwave vulcanization foaming process extrusion molding, surface clean and beautiful, with good elasticity and compression deformation.

High temperature resistant rubber seals are often used in:

1, PVC doors and windows, aluminum doors and windows, wood doors and windows, such as building decorative doors and windows, the main role is dustproof, pest control, waterproof, sound insulation, sealing and so on.

2. Door door frame, side window, front and rear windshield, engine cover and suitcase cover, play the role of waterproof, dustproof, sound insulation, temperature insulation, shock absorption and decoration.

3, electrical cabinets sealed, it has good sealing, waterproof, fire prevention, pest control, windproof, light, anti-collision and long service life.
