PTFE sunshade membrane is a high-performance functional material consisting of a glass fiber fabric substrate coated with polytetrafluoroethylene (PTFE). It exhibits key properties including self-cleaning, superior weather resistance, diffuse light transmission, and high mechanical strength. Ideal for interior cladding in applications such as sports venues, commercial atriums, and transportation hubs, it enables lightweight, large-span structural systems with energy efficiency, long-term durability, and design flexibility for innovative spatial forms. As a premium material in modern architecture, it seamlessly integrates functional performance with aesthetic design, balancing technical excellence and visual appeal.
