That would certainly make VP more palatable.  If not due to VOC taxes, why
are the fluids so expensive?

I do not think these are ozone depleter but they are very costly.
                                                                 
 This is the statement that they give regarding there material   
 in the data you are talking about.                              
                                                                 
                                                                 
                                                                 
                                                                 
                                                                 
                                                                 
                                                                 
                                                                 
                                                                 
                                                                 
                                                                 
                                                                 
 Hence, Fomblin and Galden perfluoropolyether fluids have a ZERO 
 Ozone Depletion Potential and are not classified as VOCs by the 
 EPA.

Guenter

See http://www.ausimont.com/docs/gald_vapor.html
This gives you details of fluids with BPs of 155, 166, 200, 210, 215,
230, 240 and 260 °C. Surely you can find one to suit almost any
application in that range.

However, I repeat my earlier warning that these products are horrific
global warmers and are not exactly given away with a packet of corn
flakes.

Best regards,

Brian
