Product Introduction: The PVC waterproof membrane is a high-quality polymer waterproof sheet manufactured via extrusion, with PVC resin as the main component, supplemented by plasticizers, UV-resistant agents, anti-aging additives, and stabilizers. Its unique formula ensures a significantly 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 preferred choice in construction and civil engineering.
