Ethylene tetrafluoroethylene (ETFE)
Description (definition)
Ethylene tetrafluoroethylene (ETFE) is a thermoplastic fluoropolymer that impresses with its transparency, durability and exceptional chemical and thermal resistance. It is frequently used in demanding applications such as architecture, electronics and the chemical industry. ETFE is extremely lightweight, UV-stable and self-cleaning, making it a versatile material for innovative projects.
An example
A well-known example is the use of ETFE in modern stadium roofs such as the Allianz Arena in Munich. The combination of light transmission, weather resistance and lightness enables impressive architectural designs.
What advantages does ETFE offer compared to glass?
ETFE is significantly lighter than glass and can be used flexibly in large structures. It is self-cleaning, virtually unbreakable and allows more UV light to pass through, making it ideal for greenhouses and transparent façades.
How does the transparency of ETFE affect applications?
The high transparency of ETFE enables the use of natural light, which reduces energy costs. In addition, the material can be customized with printed patterns to minimize glare or create specific lighting conditions.
Can ETFE also be used for sustainable building projects?
Yes, ETFE is fully recyclable and has a low material consumption. It reduces the weight of structures and enables energy-efficient buildings through natural light utilization and thermal insulation.
