PVC Waterproofing Roof Underlayment
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
The PVC waterproofing Membrane formulas are based upon polyvinyl chloride resin with other assistants added to provide flexibility and stability such as anti-oxidant, absorbent of ultraviolet light, plasticizer and plastic filling agent.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.
