  • Lubricants based on polytetrafluoroethylene are used in some filling plants. These are in the form of dispersions and are not applied to the chains via nozzles, as is usually the practice, but with brushes.

In addition, the polytetrafluoroethylene adheres very strongly to the chains. In practice, it turned out to be disadvantageous that the overall hygienic condition with regard to contamination and contamination of the transport chains deteriorated. This even went so far that the performance profile of the lubricant deteriorated over time due to the increase in contamination.
