1. Plastic polyvinyl chloride sealing tape
it has the advantages of corrosion resistance, wear resistance, combustion resistance, high mechanical strength, etc. The disadvantage is that it becomes hard and fragile with the extension of time, loses elasticity, does not resist aging, has poor weather resistance, and has poor low temperature performance.
2. Ethylene glycol sealant strip
it has the characteristics of ozone proof, high temperature resistance, low temperature resistance, chemical resistance, resistance to various polar solutes, etc., and has excellent comprehensive performance. The disadvantage is that mineral oil is generally used and lubricating oil expansion has a great influence, and it is generally a dark part of the product. The operating temperature range is minus 60 degrees Celsius to 150 degrees Celsius, suitable for high temperature, low temperature, coastal areas and ultraviolet radiation, high-rise buildings.
3. Thermoplastic vulcanizate sealing strip
with the flexibility and elasticity of Chinese rubber, it can be produced by processing plastic products without sulphuretted, and waste can be recycled and reused. It is a kind of material with wide performance, good heat resistance, low relative density, oil resistance similar to neoprene, compression permanent deformation and wear resistance are not very good. Use in the temperature range of minus 40 degrees Celsius to 150 degrees Celsius. It is suitable for cold buildings and high-rise Management buildings of enterprises.
4. Polyurethane rubber sealing strip
it has good flexibility and excellent wear resistance, good hardness, good mechanical properties, excellent cold resistance **weaving and chemical resistance. It can meet the requirements of different colors of enterprises. The operating temperature range is minus 60 degrees Celsius to 80 degrees Celsius. It is suitable for earthquake-prone areas, railways, power plants and other cranes close to strong vibration areas, and also suitable for areas with strong ultraviolet radiation.
