I plant in Hebei's largest manufacturer of automotive sealing strip, its main materials are rubber and polyvinyl chloride resin, and its function is not only to automotive sealing, but also play a buffer to absorb the shock and to maintain the role of glass, for the car is a kind of seal carving without decoration.
    As a pre-material for automotive sealing strip when the use of natural rubber, and later with the continuous development of technology synthetic ethylene, propylene rubber and nitrile rubber is rapidly becoming the main material of the sealing strip, the nature of the material of the sealing strip has a more high demand: weather resistance, wear resistance, low water absorption, low residual deformation at low temperature can maintain good flexibility, has a non-polluting.
    Automotive sealing strips are a lot of parts of the entire body of the needs of the most widely used vehicle body sealing area, the most different sealing state seal relatively high degree of difficulty, so the body of the seal to achieve common compression method, bending method, complex method three ways, in order to achieve the overall seal of the vehicle body.
