Hi JLP
The main way of producing polyfluoro greases is the combining of the polyfluoro base oil with teflon as they are chemically similar, the two combine together into a continous gel that behaves as a grease.
There is no real difference to most of the polyfluoro greases that we are aware of, we completed extensive static heat exposure testing on the range of polyflouros' available to us and most performed similar apart from one product, report available if you email us (lab@rttech.com.au).
Polyflouros are always going to be far more expensive to manufacturer than "normal" lubricants as the feed stocks are an extremly corrosive gas that requires specialised plants.
The main advantage is high temperature work, maybe 200°C if unable to relubricate long term and up to 300°C if you can relubricate to compensate for the base oil gassing off thickening the grease and causing slip stick.
Polyflouro lubricants are over 1 in density and there can be a heavier loading advantage from the products as well.
Hope this assists
Happy New Year
