PVC ROOFING MEMBRANES
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. Good combination of high elasticity and tensile strength.
2. Fine resistance to static electricity.
3. Excellent resistance to ageing / weathering.
Application Range
Reinforced PVC waterproof membrane forms an effective barrier to liquid water or water vapor in the roof construction for industrial and civil engineering, underground engineering such as subway & tunnel, water conservancy such as water pools & ditch, shelter, grain depot, land filling, dyke, sewage treatment and basement.
