About cars, we often pay attention to the tires, engines and so on, but the sealing strip also has a great role in the car. Today xiaobian to share with you the types and functions of the sealing strip. In order to help you better understand the sealing rubber strip, today's editor for the majority of owners to introduce.

  Classification of automobile sealing strip:

  1, vulcanized rubber sealing strip

  Vulcanized rubber sealing rubber strip has outstanding ozone resistance, excellent weather resistance, good high temperature and low temperature resistance, outstanding chemical resistance, can withstand a variety of polar solutes, the relative density is small. The disadvantage is large expansion in mineral oil and lubricating oil. Operating temperature range -60~+150C.

  2, silicone rubber sealing strip

  With outstanding high and low temperature resistance, ozone resistance and weather resistance; Excellent hydrophobicity and proper air permeability; Unparalleled insulation performance; It can meet the requirements of food hygiene hygiene level, can meet the requirements of various colors. Disadvantages are the worst mechanical strength in rubber materials, oil resistance. Operating temperature range -100~+300C. Can be used in high temperature, cold, ultraviolet radiation areas and high-rise buildings.

  3, neoprene sealing rubber strip (CR)

  Compared with other special rubber, individual performance is poor, but the overall performance balance is good. It has excellent weather resistance, ozone resistance, heat aging resistance, oil resistance and solvent resistance, good chemical resistance and excellent fire resistance, and good adhesion. Poor storage stability, storage process will occur hardening phenomenon, cold resistance is not good. Relatively high density. They are usually made in black. Suitable for oil resistance, heat resistance, acid and alkali resistance environment. Operating temperature range 30~+120°C.

  4, nitrile rubber sealing strip

  The main characteristics are oil resistance, solvent resistance, but not ketone, ester and chlorinated hydrocarbons and other media, elastic and mechanical properties are very good. Disadvantages are easy to aging and cracking in ozone and oxidation, cold resistance, low temperature resistance.

  5, thermoplastic elastomer type sealing strip

  It has good elasticity and excellent abrasion resistance, good oil resistance, wide adjustable range of hardness (Shore A hardness 65~80 degrees), excellent mechanical properties (tensile strength, elongation at break), excellent cold resistance and chemical interweave corrosion resistance, high price of raw materials. For recyclable materials. Operating temperature range -60~+80C. It is suitable for earthquake prone areas, railway nearby or factory buildings with high-power cranes and other areas with strong vibration, as well as areas with strong ultraviolet radiation.

  6, thermoplastic vulcanized rubber (TPV) sealing strip

  With the flexibility and elasticity of rubber, plastic processing method can be used for production, no vulcanization, waste can be recycled and reused. Is a wide range of performance of the material, heat resistance, cold resistance is good, the relative density is small, oil resistance, solvent resistance and neoprene similar, compression resistance permanent deformation and wear resistance is not very good. Operating temperature range -40~+150°C. Can be used in cold, as well as high-rise buildings.

  7, plasticized polyvinyl chloride (PPVC) sealing strip

  The material is cheap and easy to obtain, with corrosion resistance, wear resistance, acid and alkali resistance and all kinds of chemical media, combustion resistance, high mechanical strength; The disadvantage is that the plasticizer in the system is easy to migrate, and becomes hard and brittle with the extension of time, losing elasticity, aging resistance, weather resistance and low temperature performance. It is usually made of dark color. Suitable for light is not strong, temperature change is not bad weather conditions.

  8. Surface coating material

  Polyurethane, silicone, ptfe and other materials are coated on the surface of the sealing strip to replace the surface flocking of the traditional process. The coated sealing strip has good wear resistance and smoothness, especially the sealing strip coated with silica gel surface coating. The surface friction coefficient is small, which is conducive to the sliding of doors and Windows. It is suitable for Windows and doors with sliding doors and sashes. It is the substitute of traditional silicified top.

  Rubber sealing strip can improve the tightness, automotive sealing strip is one of the important parts of the car -, widely used in the body, chairs, doors, Windows, skylights, engine case and trunk parts, the machine can produce the rubber for installing bus luggage compartment door hinge, also have other waterproof, sealing effect, can effectively prevent the rain into the car.
