PVC Flat Roofing Material
Product Description
Reinforced waterproof membrane forms an effective barrier to liquid water or water vapor in the roof construction for industrialThis membrane is polyester reinforced, which provides high breaking and tearing strength needed to prevent excessive elongation and sheet deformation under the stresses produced by the lifting of the membrane under wind loads.
Product Features
They have good properties compared to that of Butyl, EDPM and HYPALON based water proofing membrane. They have high tensile strength and elongation properties are added to provide flexibility and stability such as anti-oxidant, absorbent of ultraviolet light, plasticizer and plastic filling agent.
