PVC Geomembrane - Good Hot Melt Performance/Easy Welding

Three pieces of transparent PVC geomembrane samples is lying on the black background.

PVCG-1: Transparent PVC geomembrane.

PVC geomembrane is polyvinyl chloride waterproof board. It is a kind of superior quality, high polymer waterproof sheet. By adding plasticizer, anti ultraviolet agent, anti aging agent, stabilizer and other processing aids into PVC resin, through extrusion method to produce molding high polymer waterproof coiled material. Composite PVC geomembrane is formed by PVC sheets and geotechnical cloth. With the advantages of high tensile strength, high and low temperature resistance and good thermal performance, roll seams can use cold sticking method or hot air welding method, which leads to form joint bond firmly, closed tight overall waterproof layer. PVC geomembrane can satisfy the water conservancy, municipal, construction, transportation, subways, tunnels and other civil engineering anti-seepage, separation, reinforcement and anti crack conditions.
