Door and window seals are commonly used as follows:
1, plasticized PVC sealing tape
Materials are cheap and easy to get, with corrosion resistance, wear resistance, flame resistance, high mechanical strength; The disadvantage is that the plasticizer in the system is easy to migrate, with the extension of time to become hard and brittle, loss of elasticity, aging, weather resistance and low temperature performance is poor. Generally dark color products. Suitable for occasions where the light is not strong, the temperature does not change much and the weather conditions are not bad.
2, epdm sealing tape
Excellent comprehensive performance, ozone resistance, high and low temperature resistance, chemical resistance, resistance to a variety of polar solute, relatively small density. Disadvantage is in general mineral oil and lubricating oil in the expansion of large, generally dark products. Operating temperature range -60 ~ +150℃, with its excellent comprehensive performance, has been widely recognized in the industry. It is suitable for high temperature, cold, coastal area and high - rise buildings.
3, thermoplastic vulcanization rubber seal tape
With the flexibility and elasticity of rubber, it can be produced by the plastic processing method without curing, and the waste can be recycled and reused. Is the performance of a wide range of materials, heat resistance, cold resistance is good, relatively small density, oil resistance, solvent resistance and neoprene similar, compression deformation and abrasion resistance is not good. Can meet the requirements of a variety of colors, using temperature range -40 ~ +150℃. Applicable to cold, as well as high - rise buildings.
4. Polyurethane rubber seal strip
It has good elasticity, excellent abrasion resistance, good oil resistance, wide hardness adjustable range (65-80 degrees of A), excellent mechanical properties (tensile strength, elongation at break), excellent cold resistance and chemical resistance, high price of raw materials. For recyclable materials. Can meet the requirements of various colors. Operating temperature range -60 ~ +80℃. It is applicable to the areas with frequent earthquakes, the areas near the railway or the factory buildings with high-power cranes and other areas with strong vibration, as well as the areas with strong ultraviolet radiation.
5, silicone rubber seal tape
Outstanding high and low temperature resistance, ozone and weather resistance; Excellent hydrophobicity and proper permeability; With unparalleled insulation performance; Can reach the food hygiene requirements of the hygiene level, can meet the requirements of various colors. The disadvantage is the mechanical strength in rubber material * poor, oil - resistant. Operating temperature range -100 ~ +300℃. It can be used in high temperature, cold, ultraviolet radiation and high - rise buildings.
