I don't know. Maybe this why they use the CO2 in the half CO2/404a mix, to quell some of the properties that make R-404a a good heat mover.
I cant find any definitive, aaa ha, reason for the CO2 that stands out.
The 2 main ingredients of R-404a are kind of cool.
R-143a (aka canned air) has some interesting inferred absorbing properties.
R-125, HFC-125 is kind of neat too, in its other life its used for fire suppression, it pulls heat away from burning material so fast it shuts down the combustion decompression process, in addition to suffocating the fire. Not a bad material to have inside your tire.
R-134a, (only 4% of the blend) is there to make the other 2 play nice when inside a heat pumping system.
So R-125 sounds like the best thing, but I would be willing to bet its already been tried by its self and not favored.
