PTFE structural membrane is primarily composed of Teflon and a fiberglass base fabric. Compared to other membrane structural products, it demonstrates superior resistance to chemical corrosion and UV degradation, with an outdoor service life exceeding 25 years.
The ultra-high molecular structure of PTFE endows it with exceptional self-cleaning properties in natural environments, allowing its lifespan to align almost seamlessly with that of the building itself. Among all membrane structure materials, PTFE exhibits the highest level of fire resistance. Huifeng’s PTFE membrane products offer outstanding structural strength, durability, and aesthetic appeal, and are designed to retain their white appearance permanently. Given these advantages, this product is poised to become the mainstream material in the high-end tensile structure market in the coming years.

Unique optical properties: incident light during the day becomes natural warm light, and the light is evenly distributed; high reflectivity at night gives the room excellent lighting effects and reduces energy consumption.
Excellent self-cleaning ability: surface dust can be washed away by rain, keeping the building clean, and the service life is three times that of ordinary structural membranes.High light transmittance: the light transmittance can reach more than 20% after sun exposure, with strong heat dissipation capacity and less heat absorption.The service life exceeds 25 years.
