The characteristics and applications of ETFE air pillows

ETFE air cushions are inflatable structures made from ethylene-tetrafluoroethylene copolymer films. With their lightweight, high light transmittance, weather resistance, and self-cleaning properties, they have become an important innovative material in modern architecture.

Core Characteristics:
* **Lightweight and High-Strength:** Weighing only 1% of glass of the same area, with high tensile strength, capable of withstanding wind and snow loads.
* **High Light Transmittance:** Light transmittance can reach 95%, effectively improving building lighting efficiency.
* **Weather Resistance and Long Lifespan:** Resistant to UV rays, high temperatures, and humidity, with a service life of 25-35 years.
* **Self-Cleaning:** Smooth surface, easily cleaned by rainwater, low maintenance costs.
* **Moldability and Environmental Friendliness:** Can be thermoformed into various curved surfaces, 100% recyclable, supporting green building practices.

Typical Applications:
* **Large Public Buildings:** Such as the Beijing "Water Cube" (National Aquatics Center), the Allianz Arena in Germany, etc.
* **Transportation Buildings:** Such as Guigang High-Speed ​​Railway Station, Guangzhou South Railway Station, Yujiapu High-Speed ​​Railway Station, etc., used to achieve lightweight roofs and natural lighting.

Other examples include the new Yogyakarta International Airport and the Eden Project in the UK.
