Polymer fume fever

Polymer fume fever or fluoropolymer fever, also informally called Teflon flu, is an inhalation fever caused by the fumes released when polytetrafluoroethylene reaches temperatures of.

Fever

When PTFE is heated above the pyrolysis products are different and inhalation may cause acute lung injury. Symptoms are flu-like with chest tightness and mild cough. Onset occurs about 4 to 8 hours after exposure to the pyrolysis products of PTFE. A high white blood cell count may be seen and chest x-ray findings are usually minimal.
The polymer fumes are especially harmful to certain animals whose breathing, optimized for rapidity, allows in toxins which are excluded by human lungs. Fumes from Teflon in very high heat are fatal to parrots, as well as some other birds.
