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 .
