The application of ETFE membrane materials can replace other products in many aspects and show strong advantages and market prospect. The most representative building in recent years is the 2006 World Cup main stadium in Munich, Germany, Allianz Arena, and the 2008 Beijing Olympic Games "Water Cube" national Swimming Center. With the 2006 Germany World Cup and the 2008 Beijing Olympic Games held two major sporting events, more and more people began to contact this new form of architecture, China has been completed in Nantong Botanical Garden, Suzhou Industrial Park and other air cushion-type structural engineering.

ETFE film surface is very smooth, with excellent self-cleaning, dust, stains with rain washed away. For the appearance of artificial cleaning, generally 4 years to do once. The thickness of the ETFE is usually 0.1~0.25㎜ and is a superior alternative to the transparent structure. Its lifetime is at least 25-35 years and is an ideal material for permanent roof structures.

The ETFE film has self-extinguishing properties and the critical Oxygen index is the minimum oxygen concentration required for continuous combustion. The critical oxygen Index of the ETFE film is 32%, which is greater than the oxygen concentration in the atmosphere, so the film will cease to burn when the spark is away from the film.

ETFE inflatable membrane structure, through the air layer between the film to increase the purpose of insulation. The heat insulation of the air cushion varies depending on the number of layers of the membrane and the shape of the pillow. The 3-layer air cushion has the thermal insulation property of multilayer glass, and can achieve the energy saving effect of building.

ETFE material has better fire resistance, belonging to B1 grade flame retardant material. In the flame, it melts and shrinks, but no dripping material. And ETFE light, thin, as roofing materials, if encountered sudden fire, its lower structure and personnel of two times less harmful. In the event of a hail climate, the glass roof may break, and the ETFE will only leave a small dent in the surface.

The basic unit of ETFE inflatable membrane structure is air cushion, its basic working principle is to combine two layer or multilayer ETFE membrane material together to make air cushion, and in the meantime, to enter the atmosphere, to form an envelope structure system with external loading capacity. It is because of the air inside the gas cushion, and the air is a good thermal insulation material, high thermal resistance, so that the ETFE gas pillow has a high thermal insulation performance.
