is known as ETFE (sometimes also referred to as ETFE) [1] to a type of plastic of high heat resistance, corrosion and UV rays. The acronym is the acronym ETFE ethylene-tetrafluoroethylene, the material being a copolymer of this molecule. Content

Features

The ETFE is a plastic transparent outstanding durability, has a high chemical resistance and mechanical (cut and abrasion), [2] and high stability to temperature changes (supports up to 150 º C). [1] It is also combustible but not flammable. The resin is processed by extrusion, injection molding, compression, transfer and fluid pressure [1].

But his most remarkable quality is its high resistance to ultraviolet rays, [3] which allows, unlike other plastics, not yellow from exposure to lightning solar. This feature makes the ETFE as an alternative to glass in the building. [4]

The ETFE weighs 100 times less than glass, more light passes, and double layer settings or "pillow" is more insulating. It is also easy to clean and recyclable. [4]

ETFE in Architecture [edit]

Although the material was already known, the first time it was used as Glass replacement was in 1982, a flag of a zoo in the Netherlands. [5] is currently used mainly in tensile structures, [6] both monolayer and bilayer [3].

buildings made of ETFE far more emblematic are:

• "Water Cube, designed by the PTW to host the swimming events of the Beijing 2008 Olympic Games.

• The Allianz Arena in Munich, designed by architects Herzog & de Meuron.
