Product Introduction: This high-performance polymer waterproof sheet is produced by extrusion, using PVC resin as the main component, combined with plasticizers, UV stabilizers, anti-aging agents, and other processing additives. Its specialized formula grants it a much longer service life compared to standard waterproof materials: over 20 years for roof installations and more than 50 years for underground use, making it a popular choice in construction and civil engineering.
Product Description: Classified by composition type: Type H (Homogeneous Membrane) – PVC waterproof membrane without internal reinforcement or backing; Type L (Fiber-Backed Membrane) – PVC waterproof membrane with a composite lower layer of fabrics such as polyester non-woven fabric; Type P (Fabric-Reinforced Membrane) – PVC waterproof membrane reinforced with polyester or fiberglass mesh in the core layer.
