OVEN TRACKER XL2 Thermocouple Probes 37
At Temperatures Greater Than Product
400°C/752°F See note*
430°C/806°F Tetrafluoroethylene
440°C/824°F Hexafluoropropylene
475°C/887°F Perfluoroisobutylene
500°C/932°F Carbonyl fluoride*, which, in moist air,
converts to the acid gas hydrogen fluoride
* May also be produced if PTFE tape is kept at 400°C/752°F for an extended time.
Health-hazard Data
• Inhalation of decomposition products from PTFE can produce ‘polymer
fume fever’, which has symptoms similar to influenza.
• There is no risk from ingestion or skin contact.
• There are no medical conditions generally aggravated by exposure to PTFE.
Emergency and First-aid Procedures
• If there is accidental contact with PTFE fumes, remove the person
concerned to clean air.
• Self-contained breathing apparatus and protective clothing should be worn
when fire-fighting.
