Thermoplastic polyolefin (TPO) waterproofing membrane (TPO waterproofing membrane) is to ethylene propylene rubber (EP) weathering resistance and heat resistance and polypropylene welding combined with TPO resin as base material. In the early 90's, the construction of the roof waterproof by the way of mechanical fixing. Because it has both the weatherability of the EPDM rubber and plastic waterproof coiled material weldability, waterproof effect is reliable, aging resistant performance is outstanding, it is developing rapidly. With its excellent physical and chemical properties and environmental performance, the coiled material has become the fastest growing waterproof material in the world. In the United States, TPO waterproof material has been accounted for 24% of the low grade commercial roofing market in the United States, and the average annual growth rate of more than 23%. In recent years, with the development of mechanical fixed roof system, high performance and energy saving, environmental protection effect of TPO waterproof coiled material in the country also appeared the momentum of rapid development.

Variety specification

Products are divided into
