Huh....
Isn't that the same stuff they put in toothpaste to remove tartar?
Guess I'm going to have to stop putting that topping on my fish sammiches now....

R-1234yf does not itself contain hydrogen fluoride. Fluorine is a component in nearly all modern refrigerants. CFC's like R-12 (chlorofluorocarbons) were bad news because of the chlorine. Attacked the ozone layer... HCFC's, (hydrochlorofluorocarbons) like R-22 were used as an interim replacement for the CFC's. HFC's, (halofluorocarbons) like R-134a have been used to replace the HCFC's. Many of these refrigerants will break down in the presence of high heat to form Hydrofluoric acid... also known as HF. It is the HF that likes to eat glass and skin and destroy your lungs.
It is not that the newer R-1234yf is any worse from a toxicity standpoint, it's that in the right concentration it can be flammable... High heat then breaks down the refrigerant and presto.. you may get HF. However, this is a potential issue with ALL fluorinated refrigerants ... If your old '68 Pontiac caught on fire...it's A/C would burst and release HF too.

 

:lol: Refrigerant wars :lol: DuPont is like Apple, changing up their stuff up just to keep making bucks! Just go back to R12 :arf:

 

yea.....DuPont and Honeywell coming up with the next best thing. To bad they are being made in China...
