[200q20v] Re: [s-cars] Re: r12 replacement autofrost - good as r12?

[Robert Myers]

Well, Chris, if Bob Myers said it was flammable then Bob Myers screwed 
up.  The isobutane component will be flammable but when mixed with other 
gases which could best be described as fire extinguisher 
materials...  (Fairly close chemically to Halon.)  Well, it shouldn't burn 
(as in burn like gasoline or natural gas or propane).  Under high 
temperature conditions, though, it can be made to "burn" and when it does 
it can/will produce some rather unpleasant thermal decomposition products.

If I remember correctly, the discussion back in '98 concerned the use of 
hydrocarbon refrigerants such as isobutane and/or isobutane mixed with 
propane.  Such mixtures will be highly flammable.  Almost explosively so 
when provided with oxygen and a source of ignition.

Then again you may be witnessing signs of advancing Alzheimer's.
