1.5mm homogeneous pvc waterproof membrane for roofing

 

Product Information

PVC roofing membrane is a highly-engineered,new-type membrane manufactured

using polyvinyl chloride as main materials and added other chemicals such as anti-oxidant,anti-UV materials to make it flexible,stable and UV-resistant. 

 

Product Features

1. No pollution to the environment;

2. Fine tensile strength,elasticity,no deformation under hot or

    cold temperature conditions;

3. Easily welding,firm and secure;re-weldable after weathering within their lifetime;

4. Fine resistance to static electricity;

5. Fine resistance to UV ;

6. Root-resistance and suitable for planting roofs;

7. Fine resistance to weathering and ageing;

8. Keep good flexibility under low temperature;

9. Fine puncture resistance,joint peel strength and joint shear strength property;

10. Easy treatments on delicate parts of corners and edges.

 

Application Range

PVC membranes form an effective barrier to liquid water or water vapor in the roof construction for industrial and civil engineering, underground engineering such as subway ditch, shelter, grain depot, land filling, dyke, sewage treatment and basement
