PTFE

Polytetrafluoroethylene (Teflon (®))

PTFE has a very high resistance to almost all chemicals. Exceptions are liquid alkali metals and fluorine gas under pressure.

The outstanding properties of PTFE are its good sliding properties, low wear and high temperature resistance (-200 °C up to +260 °C). However, since PTFE has a hardness of approx. 95 °Shore, meaning it is hardly elastic, the installation of O-rings in split grooves is recommended, or coated versions are preferable.

Fillers, eg bronze-filled compounds, give PTFE the ability to adapt to most application conditions. Important properties of this plastic such as compressive strength, abrasion behavior, conductivity, etc. can be specifically optimized by adding appropriate fillers.

Disposal

According to the “Regulation on the European Waste Catalogue (AVV)”, the waste product made of PTFE can be classified according to Chapter 7 “Wastes from organic chemical processes” and the waste code 07 02 99. This waste code stands for waste classified as non-hazardous.

They can therefore be disposed of in normal household quantities with normal household waste. Please use the container provided by your public waste disposal authority for residual waste as the appropriate disposal container.
