Attention Thermocouple Probes

PTFE is non-flammable. Temperatures greater than +260 °C will cause a thermal

decomposition of the product and release small amounts of toxic fumes. The most

important decomposition products are:

Temperatures greater than Product

+400 °C See note *1

+430 °C Tetrafluorethylene

+440 °C Hexafluorpropylene

+475 °C Perfluorisobutylene

+500 °C Carbonyl fluoride (*1), which, in moist air, converts to the

acid gas hydrogen fluoride

*1 Carbonyl fluoride may also be produced if the PTFE tape is kept at +400 °C (752 °F)

for an extended period of time.

Health Hazards:

The inhalation of PTFE decomposition products form PTFE can produce ‘Polymer Fume

Fever’ with the same symptoms as 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:

In case of a PTFE fume accident, the affected person has to be rescued from the danger

area immediately. Self-contained breathing apparatus and protective clothing are

indispensable when fire-fighting.
