Product Introduction: As a high-quality polymer waterproof sheet, this PVC waterproof membrane is manufactured by extrusion, with PVC resin as the main raw material, supplemented by plasticizers, UV stabilizers, anti-aging agents, and other processing aids. Due to its exclusive formula, the product’s service life is significantly longer than that of 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.
