The material of the sealing strip is rubber, paper, metal, plastic, etc. At present, there are mainly five kinds of sealing strip materials: PVC sealing strip, silicone sealing strip, EPDM sealing strip, TPV sealing strip, TPE sealing strip.

The traditional sealing strips we use are PVC sealing strips. The price of PVC sealing strip materials is relatively low; the quality of PVC sealing strips is also different. Because PVC is not conducive to environmental protection, foreign developed countries and domestic Beijing and coastal cities have eliminated or restricted the use of PVC tape.

Advantages of PVC sealing strip:

1. Good processing performance;

2. Low manufacturing cost;3. It has good characteristics of corrosion resistance and insulation.
