Ethylene tetrafluoroethylene, known also by its acronym ETFE, is a thermplastic fluorocarbon-based polymer (a fluoropolymer). It was originally designed to have high corrosion resistance and strength over a wide temperature range.Compared to glass, ETFE film is 1% the weight, transmits more light and is also resilient, self-cleaning (due to its nonstick surface) and recyclable.An example of its use is as pneumatic panels covering the outside of large sport complexes, such as football stadium Allianz Arena or the Beijing National Aquatics Centre – the world‘s lar- gest structure made of ETFE film, well known also as the „Water Cube“.The most known brand names of ETFE include Tefzel by DuPont, Fluon by Asahi Glass Company and Neoflon ETFE by Daikin.

Used for both roofs and facades, ETFE film presents unlimited design options due to the material‘s light weight, flexibility and transparency. ETFE film can be used in place of traditional glass and plastic for permanent or temporary structures. ETFE allows roof or wall weight to decrease drastically compared with glass. Because the material does not shatter upon impact, architects are also using ETFE in place of glass in applications where blast mitigation is a concern. When ETF E film is used in a two- or three-layer model incorporating an air space, it provides an excellent insulating capability, as effective as insulating glass. Depending on project specification, there are several ETFE films available to customize UV protection and light control, including transparent, matte, white and printed. The sustainable material is recyclable and provides superior durability. ETFE can last over 20 years without losing its transparency or strength. Due to its nonstick surface, ETFE resists airborne pollutants and odors, making it chemically-resistant and naturally self-cleaning.
