2. Perfluoroalkoxy alkane - Wikipedia

   en.wikipedia.org/wiki/Perfluoroalkoxy_alkane

   Perfluoroalkoxy alkanes (PFA) are fluoropolymers. They are copolymers of tetrafluoroethylene (C 2 F 4) and perfluoroethers (C 2 F 3 OR f, where R f is a perfluorinated group such as trifluoromethyl (CF 3)). The properties of these polymers are similar to those of polytetrafluoroethylene (PTFE). Compared to PTFE, PFA has better anti-stick ...

   PTFE tubing is used for Bowden tubing in 3D printers because its low friction allows the extruder stepper motor to push filament through it more easily. PTFE is commonly used in aftermarket add-on mouse feet for gaming mice to reduce friction of the mouse against the mouse pad, resulting in a smoother glide.
