PVC Roofing Membrane

Product Detail

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.

Categories	Introduction	Standard	Item NO.
P Type	Membrane reinforced by embedded fiber    mesh(fiberglass mesh,polyester fabrics). This is usually suitable for    single-ply waterproof system for roof by welding and mechanical fastening.	GB27789-2011	DYP-816
H Type	Homogeneous membrane.  This is usually suitable for  metal roof, general basic construction.	GB27789-2011	DYP-817
L Type	Membrane reinforced by non-woven    fabric backing.  This is usually    suitable for concrete roof by welding and adhesion.	GB27789-2011	DYP-818



 




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.

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.
