What is ETFE made of?
ETFE Foil is a plastic polymer related to Teflon and is created by taking the polymer resin and extruding it into a thin film. Transparent windows are created either by inflating two or more layers of foil to form cushions or tensioning into a single skin membrane.
Is ETFE a Teflon?
Innovating Architecture with Teflon™ ETFE Industrial Coating Systems. Considered one of the most durable fluoropolymer coatings, Teflon™ ethylene tetrafluoroethylene (ETFE) industrial coatings are used widely across the chemical, power, energy production, and semiconductor industries.
Can ETFE be made from recycled plastic?
Fabrication of the foil involves welding large sheets of the ETFE; this is relatively quick and again a low energy consumer.” Because ETFE is also recyclable, the environmental culpability is not in the polymer, but in the aluminum frames that hold the plastic layers.
Is ETFE a plastic?
Ethylene tetrafluoroethylene (ETFE) is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range. It is also known under the brand name Tefzel.
Does ETFE block UV rays?
All Answers (1) While maintaining a high light transparency (94-97% towards visible light and 83-88% towards ultraviolet light depending on the thickness), ETFE can considerably reduce the dangerous UV-B and UV-C radiation (which causes burning and is carcinogenic) through filtration compared with open air environment.
How do I make ETFE?
The production of ETFE involves the transformation of the monomer TFE in to the polymer ETFE using polymerisation; no solvents are used in this water based procedure. The material is then extruded to varying thicknesses depending on application; a process which uses minimal energy.
What kind of material is chemfilm ETFE made of?
ChemFilm ® ETFE fluoropolymer film is manufactured by Saint Gobain Performance Plastics from a copolymer of ethylene and tetrafluoroethylene resin. This material offers the outstanding performance of fluoropolymer film over a temperature range from cryogenic to 165°C (330°F).
What is the working temperature of ETFE plastic?
ETFE has a working temperature range of -200°C to 150°C. ETFEs are only used for relatively high-performance applications related to heat, low temperature, chemical internes, and electrical insulation. Because ETFE is a semi-transparent material, it can also be used as a viable replacement for glass or traditional plastic.
How is ETFE used in composite molding film?
The low density of this material, compared to Saint-Gobain’s FEP film, provides greater coverage per pound for composite molding release film applications. The low surface energy of ETFE can also be utilized in applications such as wall coverings and anti-graffiti protection for high traffic areas.
What are the mechanical properties of ETFE E2 film?
Saint-Gobain’s ETFE E2 film offers excellent mechanical properties and tear resistance. The high light transmission (> 95%) of ETFE film, when combined with its excellent mechanical and chemical properties, provides excellent performance in architectural roofing designs and greenhouses.
