[citation needed] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [3] a spin-off from DuPont, which originally discovered the compound in 1938. [3] Polytetrafluoroethylene is a fluorocarbon solid , as it is a high- molecular-weight polymer consisting wholly of carbon and fluorine .
A recent record number of cases of polymer fume fever, also known as "Teflon flu," are putting a spotlight on one of the most common causes of the condition, the use of nonstick pans. Over 265 ...
Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. Other brandnames are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful ...
Fluorine-containing durable water repellent makes a fabric water-resistant. Fluorinated surfactants or fluorosurfactants are a subgroup of PFAS characterized by a hydrophobic fluorinated "tail" and a hydrophilic "head" that behave as surfactants. These are more effective at reducing the surface tension of water than comparable hydrocarbon ...
Teflon flu, aka polymer fume fever, is a term used to describe people who have gotten sick after being exposed to fumes from Teflon pans, according to the National Capital Poison Center.
For this winter’s COVID-19 surge, Justman says that hospitalizations are expected to peak at a rate higher than during this past summer’s surge but probably lower than during last winter's peak.
In 1945, DuPont commercialized PTFE as Teflon. They found that PTFE was resistant to corrosion, had low surface friction, and high heat resistance. [17] Tetrafluorethylene (TFE) can cyclize with a wide variety of compounds which led to the creation of a range of organofluorine compounds.
The substance was found to have several unique properties, including very good corrosion-resistance and the lowest coefficient of friction of any substance yet manufactured. PTFE was first used to make seals resistant to the uranium hexafluoride gas used in development of the atomic bomb during World War II, and was regarded as a military ...
