Product Introduction: This high-grade polymer waterproof sheet is produced by extrusion, using PVC resin as the base material, combined with plasticizers, UV stabilizers, anti-aging agents, and other processing additives. Thanks to its specialized product formula, the service life of the product far surpasses that of general waterproof materials: over 20 years for roof use and more than 50 years for underground applications, leading to its extensive adoption in construction and civil engineering projects.
Product Description: Divided by composition: Type H (Homogeneous Membrane) – PVC waterproof membrane without internal reinforcement or backing material; Type L (Fiber-Backed Membrane) – PVC waterproof membrane with a lower surface compounded with fabrics such as polyester non-woven fabric; Type P (Fabric-Reinforced Membrane) – PVC waterproof membrane reinforced with polyester or fiberglass mesh in the middle layer.
