What is ETFE used for?
ETFE was originally developed in the 1970s by DuPont as a lightweight, heat resistant film to serve as a coating for the aerospace industry. Since that time, the film has been used sporadically in various agricultural and architectural projects, such as coverings for greenhouses and protection for solar cells.
How is ETFE applied?
ETFE is strong and lightweight. It is often applied in layers that are welded together around the edges and held by a metal framework. Because it is safer and more adaptable than glass, non-rip ETFE is often used as a replacement for glass.
Is ETFE a fluoropolymer?
ETFE [poly(ethene-co-tetrafluoroethene); CAS: 25038-71-5] has: Excellent resistance to extremes of temperature. Excellent chemical resistance….Typical Characteristics and Properties of ETFE.
| Fluoropolymer | FEP |
|---|---|
| Melting Temperature °C | 260-282 |
| Tensile Modulus MPa | 345 |
| Elongation at Break % | ~300 |
| Dielectric Strength kV/mm | 19.7 |
How is ETFE produced?
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.
How expensive is ETFE?
ETFE pricing can average between $125 and $185 per square foot.
What is the difference between ETFE and PTFE?
PTFE is constructed from carbon and fluorine atoms whereas ETFE is built from carbon, fluorine and hydrogen. However PTFE has a coefficient of friction at one-third of ETFE making it more suitable when a high flow is needed as it helps reduce pipe friction Losses.
How strong is ETFE?
ETFE has an approximate tensile strength of 42 MPa (6100 psi), with a working temperature range of 89 K to 423 K (−185 °C to +150 °C or −300 °F to +300 °F). ETFE resins are resistant to ultraviolet light. An artificial weathering test (comparable to 30 years’ exposure) produced almost no signs of film deterioration.
How sustainable is ETFE?
Sustainability. The fact that ETFE doesn’t degrade under; UV light, sunlight, weather or pollution, means that ETFE could have a life of around more than 50 years (Ref 12). ETFE sheets are easily dismantled and are recyclable, with 100% of the material being recycled into new ETFE materials and products (Ref 11).
How do I install ETFE?
ETFE Film Installation
- Placement of aluminum profile on the construction.
- Final form of the etfe system before being inflated with air pressure.
- Assembly of the machinery and installation.
- Making the final checks before inflation.
- Starting inflation.
- Completing the inflation.
- Balancing the air pressure.
What is ETFE glass?
Ethylene Tetrafluoroethylene (ETFE) is a fluorine-based plastic polymer that offers a creative and lightweight alternative to glass. Developed over 40 years ago, ETFE has a similar light transmission to glass, but at just 1% of the weight.
Is tefzel the same as Teflon?
In chemical resistance, it is essentially the same as the other Teflon™ fluoropolymers. Tefzel™ ETFE Tefzel™ ETFE has nearly the same chemical resistance performance as Teflon™ PTFE and offers superior abrasion resistance, strength, and stiffness.
How is EFTE committed to making life changes?
We are committed to learning how to make life changes–from really small to really big–that strengthen our ecosystems. Through educational experiences, community engagement, research, and online resources we provide opportunities for anyone to cultivate stronger people-plant relationships.
What does EFTE stand for in hotel category?
Abbreviations.com defines the acronym EFTE as “Equivalent Full-time Employee.” I know from experience that most hotels do not use EFTEs on their daily reporting and the use of EFTEs on their financial statements is not prevalent. The creation and use of this powerful statistic is not difficult. All the information you need, you already have.
