Single-ply PVC waterproof membrane
homogeneous non-composite membranes (PVC-H)
Products Description
The PVC waterproofing rolls 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.
PVC waterproofing 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. Excellent weathering characteristics,
2.High tensile strength and long-term flexibility.
3. Excellent resistance to harsh chemicals and industrial pollutants.
4.Heat or solvent-welding effectively provides seamless roof coverings
5.Can be choice for various methods of attachment and any shape of roof
