The main components of PTFE Structure membrane are teflon and fiberglass base fabric. Compared with other structure membrane products, PTFE membrane has strong resistance to chemical corrosion and ultraviolet erosion, and has an outdoor service life of more than 25 years.PTFE's ultra-high molecular structure gives it excellent self-cleaning ability in the natural environment, and its service life is almost the same as that of the building. PTFE structure membrane is the product with the strongest fire resistance among all membrane structure materials. Huifeng's product has good structure strength, durability and beauty, and can remain white permanently. In the future, this product will become the mainstream material in the high-end tensile structure market.
