Polyvinyl Chloride (PVC) waterproof membrane is a new polymer waterproof membrane which is made from polyvinyl chloride resin, and mixed with plasticizer, filler, antioxygen, ultraviolet absorber and other auxiliaries.  we adopts automatic mixing of raw material, double-screw extruder and delicate three-roller calender equipment in the PVC membrane production. PVC waterproof membrane features dimensional stability and high tensile strength, being a best choice for many civil and industrial projects. PVC waterproof membrane mainly falls into two categories: Homogeneous & Reinforced, each with different thickness specifications. Reinforced PVC waterproof membrane employs a fabric reinforced layer in the middle, it enhances the breaking and tear strength.
