PVC Waterproof Membrane

homogeneous non-composite membranes (PVC-H) 

 

1. 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. 

 

2. 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
