1. Vulcanized rubber sealing tape
    Generally it is made of EPDM material. It has excellent generalization function, excellent ozone resistance, excellent weather resistance, good high temperature and low temperature resistance, outstanding chemical resistance, a variety of polar solutes, and low relative density. The disadvantage is that it has a large expansion in general mineral oil and lubricating oil, and it is generally a dark-colored product. Operating temperature scale-60~150℃. With its wide application scale and excellent summarization function, it has been recognized by domestic and foreign industry enterprises.
 
    2. Silicone rubber sealing tape
 
    It has outstanding high and low temperature resistance, ozone resistance and weather resistance; it has excellent hydrophobicity and proper air permeability; it has unparalleled insulation function; it can reach the cleaning level required for food cleaning, and can meet the requirements of various colors. The disadvantage is that the mechanical strength is the worst among rubber materials, and it is not resistant to oil. The operating temperature scale is -100~300℃. It can be applied to areas with high temperature, ice cold, intense ultraviolet ray and mid-to-high-rise buildings.
 
   3. Neoprene sealing tape (CR)
 
    Compared with other special rubbers, the individual functions are worse, but the overall functions are well balanced. It has excellent weather resistance, ozone resistance, heat aging resistance, oil and solvent resistance, good chemical resistance and excellent flame resistance, and outstanding adhesion. Poor storage stability, hardening occurs during storage, and cold resistance is not good. The relative density is relatively large. Generally black products. It is used in the environment where oil resistance, heat resistance, acid and alkali resistance are required. The operating temperature scale is -30~120℃.
 
    4. Nitrile rubber sealing strip
 
    The main feature is oil resistance and solvent resistance, but it is not resistant to media such as ketones, esters and chlorinated hydrocarbons. It has good elasticity and mechanical functions. The disadvantage is that it is easy to age and crack in ozone and oxidation, and has poor cold resistance and low temperature resistance.
 
  5. Thermoplastic elastomer sealing tape
 
    It has good elasticity and excellent abrasion resistance, good oil resistance, a wide range of adjustable hardness (Shore A hardness 65-80 degrees), excellent mechanical functions (tensile strength, elongation at break), excellent The cold resistance and chemical resistance are intertwined with corrosion functions, and the price of raw materials is higher. It is a recyclable material. The operating temperature scale is -60~80℃. It is suitable for earthquake-prone areas, near railways or factories with high-power cranes and other intensely sensational areas, as well as areas with intense ultraviolet rays.
 
    6. Thermoplastic vulcanizate (TPV) sealing tape
 
    It has the flexibility and elasticity of rubber and can be produced by plastic processing methods without vulcanization. The waste can be recycled and reused. It is a material with a wide range of functions, with excellent heat resistance and cold resistance, low relative density, oil resistance and solvent resistance similar to neoprene, and resistance to shrinkage, permanent deformation and abrasion resistance are not very good. The operating temperature scale is -40~150℃. It can be applied to cold and mid-to-high-rise buildings.
 
   7. Plasticized polyvinyl chloride (PPVC) sealing tape
 
    The material is cheap and easy to obtain, has corrosion resistance, abrasion resistance, acid and alkali resistance and various chemical media, resistance to incineration, and high mechanical strength; the disadvantage is that the plasticizer in the cooperative system is easy to move, and it becomes harder and brittle with time extension, and loses elasticity. , Not resistant to aging, poor weather resistance and low temperature function. Generally dark products. It is suitable for occasions where the light is not strong, the temperature changes little, and the climatic conditions are not bad.
 
    8. Exterior coating materials
 
    It is to coat polyurethane, silicone, polytetrafluoroethylene and other materials on the surface of the sealing strip to replace the flocking of the traditional process. The coated sealing strip has outstanding abrasion 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. Suitable for doors and windows with sliding doors and sashes. It is a substitute for traditional siliconized tops
