Let's talk about what kind of sealant tape is usually used for doors and windows.

There are many kinds of sealing strips for doors and windows, generally including PVC, EPDM sealing strips, silicone, TPV and other materials.

PVC has the advantages of corrosion resistance, wear resistance, flame retardancy and high mechanical strength. The disadvantage is that it becomes hard and fragile, loses elasticity, is not aging-resistant, and has poor weather resistance and low-temperature performance.

TPV thermoplastic vulcanized rubber sealing strip has the flexibility and elasticity of china rubber. It can be processed from plastic products without vulcanization, and the waste can be recycled. It is a material with wide performance, good heat resistance, low relative density and oil resistance similar to chloroprene rubber, and its compression set and wear resistance are not very good. Use in the temperature range of-40℃ to 150℃. Suitable for cold buildings and high-rise management buildings in enterprises.

EPDM is a terpolymer of ethylene, propylene and unconjugated diene, which has been commercialized in 1963. The most important feature is its excellent oxidation resistance, ozone resistance and corrosion resistance. EPDM rubber sealing strip has good waterproof, sealing and energy-saving functions, and is the most common material on door and window adhesive strips.
