Modern Design TPO PVC EPDM HDPE Waterproof Membrane Easy Application for Roof Pollution-Free Canals Dams Reservoirs

TPO (Thermoplastic Polyolefin) Waterproof Membrane    

·TPO membrane is a synthetic polymer waterproofing material manufactured through advanced polymerization technology combining ethylene propylene rubber (EPR) and polypropylene (PP) . It features excellent weldability with wide welding windows, high interlayer composite strength, and superior peel strength, forming a sealed continuous waterproof layer . The material demonstrates remarkable stability with resistance to chemical corrosion and mold growth, maintaining flexibility at -40°C . With outstanding durability (passing 7200h artificial accelerated aging test) and environmental benefits (light-colored surface with high reflectivity reducing building energy consumption), TPO membranes are suitable for industrial and civil building roofs, underground engineering, subway tunnels, and steel structure roofs.

PVC (Polyvinyl Chloride) Waterproof Membrane    

·PVC waterproof membrane is a thermoplastic material primarily composed of polyvinyl chloride resin with plasticizers, fillers, antioxidants, and UV absorbers . According to GB 12952-2011 standard, it offers high tensile strength (H and L types reaching 10MPa), large elongation, excellent puncture resistance, and weldable construction . The material is classified into homogeneous (H), fiber-backed (L), fabric-reinforced (P), glass fiber-reinforced (G), and glass fiber-reinforced with fiber backing (GL) types . PVC membranes are widely applied in building roofs, underground waterproofing projects, and green roof systems.

EPDM (Ethylene Propylene Diene Monomer) Rubber Waterproof Membrane     

·EPDM rubber membrane is recognized as one of the premier waterproof materials globally, offering comprehensive waterproof performance . It exhibits excellent ozone resistance, weather aging resistance, high tensile strength, and exceptional elongation properties . The material maintains its fundamental physical properties within a temperature range of -45°C to 80°C, with a service life typically spanning 30-50 years . Technical specifications include tensile strength ≥7.5MPa at room temperature and ≥2.3MPa at 60°C, elongation at break ≥450% at room temperature and ≥200% at -20°C, and tear strength ≥25kN/m . EPDM membranes are suitable for various industrial and civil building roofs, offices, large supermarkets, steel structure roofs, basements, tunnels, and bridges.

HDPE (High-Density Polyethylene) Waterproof Geomembrane    

·HDPE geomembrane is manufactured from high-density polyethylene resin (approximately 97.5% HDPE) with carbon black, anti-aging agents, antioxidants, UV absorbers, and stabilizers . It demonstrates superior chemical stability, resisting over 80 types of strong acids, alkalis, and salts . The material features excellent anti-aging, UV resistance, and decomposition resistance, with a service life exceeding 50 years when buried underground . With outstanding puncture resistance against most plant roots and excellent mechanical strength (tensile strength up to 28MPa, elongation at break up to 700%), HDPE geomembranes are extensively used in landfill sites, sewage treatment ponds, water conservancy projects, factory aquaculture, fish ponds, municipal engineering, landscaping, petrochemical, mining, and agricultural applications .
