What is ETFE vs PTFE?
Ethylene tetrafluoroethylene, or ETFE, is made up of carbon, fluorine and hydrogen, and is a fluorine based plastic. On the other hand, polytetrafluoroethylene, or PTFE, is made up of long strings of carbon and fluorine atoms, and is a fluorocarbon solid.
Is ETFE a Teflon?
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.
What is ETFE material?
Ethylene tetrafluoroethylene (ETFE) is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range. ETFE is a polymer and its source-based name is poly(ethene-co-tetrafluoroethene). When burned, ETFE releases hydrofluoric acid.
What is ETFE cable?
What is ETFE? ETFE, also known as, ethylene tetrafluoroethylene copolymer, insulated wires, and cables display excellent material toughness, electrical properties and good resistance to heat, flame, and chemical radiation.
How expensive is ETFE?
ETFE pricing can average between $125 and $185 per square foot.
Where is ETFE used?
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.
Is ETFE waterproof?
Type 4A — ETFE Waterproof Foil/Film Economical alternative to glass. Cost: ($$+) Upgrade to Type 1B or 2B solid waterproof screening material. Ventilation: 0% open / 100% solid (non-ventilated) Colors: White / Clear / Clear with Frit (Frit Reduces Solar Heat Gain)
What does ETFE mean?
Ethylene tetrafluoroethylene (ETFE) is a type of plastic that is fluorine-based, tough and has a high strength profile. It is widely used for chemical and electrical applications because of its useful properties. However, wires made with ETFE insulation may be prone to corrosion.
Is ETFE toxic?
With low smoke and flame characteristics, ETFE is rated 94V-0 by UL. It is odorless and non-toxic. Exhibits outstanding resistance to weather and aging, Exception UV transmission. Excellent dielectric properties.
Is ETFE a plastic?
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 ETFE flammable?
Fire: ETFE Foil as a material has low flammability (270C) and is considered self extinguishing.
What does PTFE mean?
polytetrafluoroethylene (PTFE), a strong, tough, waxy, nonflammable synthetic resin produced by the polymerization of tetrafluoroethylene. Polytetrafluoroethylene-coated, non-stick frying pan.
Is PTFE coating dangerous?
Overheating a PTFE-coated skillet can be dangerous. Very high temperatures can cause the PTFE to release gases that can give you “polymer-fume fever.” You’ll get the chills, a headache, and yes, a fever.
Is PTFE a carcinogen?
There are concerns that chemicals once used in the manufacturing process of Teflon could potentially increase cancer risk. Those chemicals have not been used in Teflon products since 2013. Today’s Teflon is considered to be safe cookware. There’s no evidence that it increases the risk of developing cancer.
Is PTFE rubber or plastic?
Fluoroelastomer (FKM) rubber is a thermoset elastomer while Polytetrafluoroethylene (PTFE) is a thermoplastic. Both are fluorinated materials comprising of carbon atoms surrounded by fluorine atoms, which gives them incredible chemical resistance.
Is PTFE better than Viton?
Viton vs Teflon (PTFE) – Viton offers a greater temperature resistance but falls short of Teflons(PTFE) chemical resistance. Also, Teflon is slightly less thermally resistant but offers much more in the way of non-adhesive properties.
Is PTFE same as Teflon?
The simple answer is that they are the same thing: Teflon™ is a brand name for PTFE and is a trademark brand name used by the Du Pont company and its subsidiary companies (Kinetic which first registered the trademark & Chemours which currently owns it).
Why is PTFE so expensive?
Processing PTFE can be difficult and expensive, because the high melting temperature, 327 °C (621 °F), is above the initial decomposition temperature, 200 °C (392 °F). Even when molten, PTFE does not flow due to its exceedingly high melt-viscosity.
What is PTFE lubricant used for?
What is PTFE lubricant used for? It is very non-reactive, and so is often used in containers and pipework for reactive and corrosive chemicals. When used as a lubricant, PTFE can reduce friction, wear, and energy consumption of machinery.
