Thermoplastic polyolefin (TPO) waterproof membrane (referred to as TPO waterproof membrane) is made of TPO resin based on the weather resistance and heat resistance of ethylene-propylene (EP) rubber combined with the weldability of polypropylene.In the early 1990s, it was used in roofing and waterproofing projects by mechanical fixed paving.Because it has both the weather resistance of EPDM rubber and the weldability of plastic waterproof membrane, reliable waterproof effect and outstanding aging resistance, it has developed rapidly.With its excellent physical and chemical properties and environmental protection properties, the coil has become the fastest growing waterproof material in the world today.In the United States, TPO waterproof membrane has accounted for 30% of the low-slope commercial roofing material market in the United States, and has maintained an average annual growth rate of more than 25%.In recent years, with the development of mechanical fixed single-layer roofing systems, high-performance TPO waterproof membrane with energy-saving and environmental protection effects has also seen rapid development in China.

Product features：

◎ Advanced polymerization technology is used to combine ethylene-propylene rubber and polypropylene, which have both the excellent weather resistance of ethylene-propylene rubber and the weldability of polypropylene.

◎ Special formulation technology, no need to add any plasticizers that can easily make the material brittle, does not produce general hot-welded coils (such as PVC) that become brittle due to plasticizer migration, and maintains long-term waterproof function.

◎ Excellent high and low temperature resistance, the same as rubber materials, it still maintains flexibility at 150℃, and maintains mechanical strength at higher temperatures.

◎ Chemical resistance, acid, alkali, salt, animal oil, vegetable oil, lubricating oil corrosion, algae, mold and other microbial growth resistance.

◎ It has excellent root puncture resistance and can be used as a root puncture resistant coil for planting roofing.

◎ Heat-resistant aging, good dimensional stability.

◎ The light-colored surface, mainly white, has a smooth surface, high reflectance, energy-saving effect and pollution resistance.

◎ The ingredients do not contain plasticizers and chlorinated polymers, no harmful gases are generated and released during welding and use, and they are harmless to the environment and human health.

◎ The lap joint is constructed by thermal welding, which can form a high-strength and reliable sealing waterproof layer.

◎ The enhanced TPO waterproof membrane is sandwiched with a layer of polyester fiber fabric in the middle, which provides the membrane with high tensile properties, high tear strength, fatigue resistance, and puncture resistance, and is more suitable for mechanical fixed roofing systems.

◎ Backing type TPO waterproof membrane The fabric on the lower surface of the membrane makes it easier for the membrane to bond with the base layer.

◎ The homogeneous TPO waterproof membrane has good plasticity and can be processed into various shapes after being heated to adapt to the practice of complex nodes.

Our Thermoplastic Polyolefin Waterproof Membrane is a high-performance solution designed to provide exceptional waterproofing and durability for a wide range of applications. This membrane is made from advanced thermoplastic polyolefin (TPO) materials, known for their excellent resistance to UV rays, chemicals, and extreme weather conditions. The Thermoplastic Polyolefin Waterproof Membrane ensures reliable protection against water infiltration, making it ideal for roofing, construction, and other waterproofing needs.

The Thermoplastic Polyolefin Waterproof Membrane features superior flexibility and strength, allowing it to withstand structural movements and thermal expansion without cracking or losing its waterproof integrity. Its lightweight yet robust composition simplifies installation and reduces the overall load on structures. This membrane's smooth surface enhances its resistance to dirt, algae, and mold growth, extending the service life of the protected surface.

One of the key advantages of the Thermoplastic Polyolefin Waterproof Membrane is its eco-friendly and recyclable nature, aligning with sustainable building practices. It offers excellent heat-reflective properties, contributing to energy efficiency by reducing cooling costs in buildings. The membrane's weldable seams create a seamless barrier, ensuring no weak points where water can penetrate.
