PVC Roofing Membrane

PVC Roofing Membrane

1.Product overview

The PVC Roofing Membrane(Exposed type) is a  composed flexible waterproof membrane made from polyvinyl chloride resin as the  main material,mixed with defoamer, aging resisting agent and ultraviolet light  absorber.
 This product has high plant-roof puncture
 resistance,so  it is widely used on roof waterproofing  projects especially plant-roof.

2.Product Categories
 fiberglass mesh, fiberglass non-woven  fabrics or polyester non-woven fabrics can be added as inner layer or backing  to enhance product tensile strength.

3.Product Features
1)The product is plant-root  puncture resistant, long service life, high tensile strength & elongation,  can effectively
 resist the destruction of the waterproof  layer due to structure deformation.

1. Resistance  to chemical corrosion & mildew, especially applicable to tunnel  waterproofing and planting roof

 waterproof engineering.

1. Aging resistant,  wind uplift resistant, heat-deformation resistant, suitable for exposed roof  system.

2. High  flexibility under low temperature,flame retardant feature ensures High construction  safety.

3. Tightly bond  with substrate on hot gas welding, perfect seam welding, and no environmental  pollution.

4.Product Specification

5.Application scope
 1)Industrial and civil building basement and  roof waterproof engineering, roofing engineering including planting
 roof,  flat roof, sloping roof, concrete roof, light steel structure roof as well as  both interior & exterior roof.
 2)Large grain depot, beam field, landfill,  artificial lake, pipe trenches & municipal engineering of waterproof, etc.
 3)Subway, road, rail tunnels, bridges, civil  air defense engineering, etc.

8.Storage
 1)Different types and  specifications of the products should be stacked respectively. Pay attention to  ventilation.
 Storage temperature should not be higher than  45?,  flat storage stack height no more than five layer, put
 single pile vertical, keep product away from  acid, alkali, oil, organic solvent, etc.
 2)Transportation  to prevent tilt or lateral pressure, cover with cloth if necessary.
 3)Under  the condition of normal storage & transportation, storage period is one  year.
