Product Introduction: The polyvinyl chloride (PVC) waterproof membrane is a high-performance polymer waterproof sheet produced through extrusion, with PVC resin as the main raw material, supplemented by plasticizers, UV stabilizers, anti-aging additives, and stabilizers. Its specialized formula grants it a service life much longer than common waterproof materials: over 20 years for roof use and more than 50 years for underground applications, resulting in widespread application in construction and civil engineering projects.
Product Description: Classified according to composition type: Type H (Homogeneous) – PVC waterproof membrane without internal reinforcing or backing materials; Type L (Fiber-Backed) – PVC waterproof membrane with a composite lower surface made of fabrics like polyester non-woven fabric; Type P (Fabric-Reinforced) – PVC waterproof membrane reinforced with polyester or fiberglass mesh in the middle.
