Polymer fume fever or fluoropolymer fever, also informally called Teflon flu, is an inhalation fever caused by the fumes released when polytetrafluoroethylene (PTFE, known under the trade name Teflon) reaches temperatures of 300 °C (572 °F) to 450 °C (842 °F).
Food-grade lubricants are specialized industrial lubricants designed for use in environments where there is potential for incidental contact with food or beverages. These lubricants are used to ensure both the proper functioning of machinery and the safety of the products being processed.
The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally invented the compound in 1938. [4] Polytetrafluoroethylene is a fluorocarbon solid , as it is a high- molecular-weight polymer consisting wholly of carbon and fluorine .
Per- and polyfluoroalkyl substances (also PFAS, [1] PFASs, [2] and sometimes referred to as "forever chemicals" [3] [4]) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million such chemicals according to PubChem.

Upon opening the cylinder, they found that the white powder was "packed onto the bottom and lower sides of the cylinder." The sample of gaseous TFE in the cylinder had polymerized spontaneously into a white, waxy solid. The polymer was polytetrafluoroethylene (PTFE). In 1945, DuPont commercialized PTFE as Teflon.
Bacteria like clostridium perfringens bacteria can produce spores, which grow and multiply rapidly in cooked food left to sit between 40 and 140 degrees Fahrenheit for longer than two hours, says ...
A convenient, safe method for generating TFE is the pyrolysis of the sodium salt of pentafluoropropionic acid: [6]. C 2 F 5 CO 2 Na → C 2 F 4 + CO 2 + NaF. The depolymerization reaction – vacuum pyrolysis of PTFE at 650–700 °C (1,200–1,290 °F) in a quartz vessel – is a traditional laboratory synthesis of TFE.
