Product Introduction: The polyvinyl chloride (PVC) waterproof membrane is a high-performance polymer waterproof sheet produced through extrusion technology. It is composed of PVC resin mixed with plasticizers, UV-resistant agents, anti-aging additives, and stabilizers. Its unique formula provides a service life much longer than ordinary waterproof materials: over 20 years for roof applications and more than 50 years for underground projects, making it widely utilized in construction and civil engineering.
Product Description: Categorized by structural type: Type H (Homogeneous) – PVC waterproof membrane without internal reinforcement or backing; Type L (Fiber-Backed) – PVC waterproof membrane with a lower layer composite of fabrics like polyester non-woven fabric; Type P (Fabric-Reinforced) – PVC waterproof membrane reinforced with polyester or fiberglass mesh in the core.
