PVC sealing strips for high-grade glass curtain wall
Over the years, PVC has been widely used in glass curtain walls due to its good properties and low cost. However, its heat aging resistance is poor compared with other rubber and thermoplastics. In our company, by adjusting the formulation, not only the heat aging resistance of PVC has been improved, but also hard-soft combined PVC sealing strips can be made according to the construct of glass curtain wall.
