Product Introduction: As a high-quality polymer waterproof sheet, the polyvinyl chloride (PVC) waterproof membrane is produced via extrusion technology, with PVC resin as the base material, supplemented by plasticizers, UV stabilizers, anti-aging agents, and other processing aids. Thanks to its unique formula, the product boasts a significantly longer service life than conventional waterproof materials: over 20 years for roof applications and more than 50 years for underground projects, making it widely used in construction and civil engineering.
