TPO (Thermoplastic Polyolefin) Waterproof Membrane is a high-performance polymer waterproofing sheet developed by combining the weather resistance of EPDM rubber with the heat-weldable properties of polypropylene materials. It is manufactured using TPO resin combined with anti-oxidation, UV-resistant, and aging-resistant additives, providing excellent durability and environmental performance.
The membrane contains no plasticizers or chlorine elements, making it safe, recyclable, and suitable for green building applications. Available in H homogeneous type, L backing type, and P polyester reinforced type, it can meet different requirements for exposed roofing, underground waterproofing, and special engineering applications.
The white reflective surface provides excellent solar reflectance, helping reduce roof surface temperature and improve building energy efficiency. The joints are connected by hot-air welding, allowing the seams to fuse with the membrane body and eliminating leakage risks caused by adhesive aging.
With outstanding resistance to extreme temperatures, chemical corrosion, root penetration, and mechanical deformation, TPO membrane is widely used in industrial buildings, photovoltaic roofs, large public buildings, tunnels, and other long-life waterproofing systems.
Key Features & Benefits
When traditional waterproofing systems face challenges from extreme weather, aging, and structural movement, QINGYUAN TPO Waterproof Membrane provides a durable and environmentally friendly solution with excellent flexibility, strength, and long-term protection.
Outstanding low-temperature flexibility maintains performance even at -40℃ without cracking in extreme climates.
High weather resistance prevents aging, hardening, and performance loss under long-term UV exposure.
Chlorine-free and environmentally friendly material contains no harmful additives and supports recyclable construction solutions.
High solar reflectivity surface helps reduce roof heat absorption and improves building energy efficiency.
Excellent tensile strength and elongation allow the membrane to adapt to substrate movement and prevent cracking.
Hot-air welded joints create a seamless waterproof layer with stronger connections than traditional adhesive bonding.
Superior resistance to chemicals, corrosion, and root penetration ensures reliable protection in demanding environments.
Safe installation without open flame reduces construction risks and improves efficiency on site.
Long-lasting performance with a service life of 30–50 years for roofs, underground structures, and industrial applications.
