Reduction of susceptibility to dirt
Resistance to extreme temperature
If spare parts with a different material can be used, the design may have to be revised. If no other material can be used due to the circumferential speeds or other influences, there is no alternative to FKM. Without PFAS, the product size increases to dissipate the heat, reduction of circumferental velocity to avoid heat generation.
In vacuum applications, greases
without PFAS decompose.

No adequate substitues on the
market.
Vacuum applications
Currently no adequate alternative to PTFE (teflon) on the market.
Limitation of resistance and durability. Loss of technical basis for the manufacturing of ball screw drives.
Loss of jobs (short term), economic effects on companies (mid term)

PFAS Applications
Resistance to extreme temperatures Resistance to extreme temperatures
Resistance to extreme environmental conditions
Protection against hazards from fire and explosion, used also in nuclear environment Resistance to aggresive chemical substances (e.g. contact with adhesives) Teflon is relevant for the function of sliding bushes Chemical resistance in aggressive media, a high temperature resistance, low friction, minimal wear (particle minimization) Resistance to extreme temperatures, aggresive chemical substances Process substance during casting processes or as adhesive materials
PFAS supports the reduction of the influence of surface roughness and leads to defoaming of the lubricant
Short-term substitution not feasible
Stop of production of brakes for elevators, in mechanical engineering products as well as in the wind industry. (Conversion from friction linings with asbestos to asbestos-free solutions took 10 years.) Tests of elastomere compatibility with a specific lubricant takes aroung 2000 h. This time is needed only to proof the suitability. The functioning test of the new substance is not included. A defined time frame of a derogation of lubricants is not suitable, because at this time no estimation related to reliable timeline exist for an appropriate substitution by PFAS free lubricants. Loss of UL certification, application in explosive atmosphere not secured
