Propylene glycol (RV antifreeze) is safer but not cheaper and it won't
get you that -134 degree protection.
You don't get -134 degree protection from ethylene glycol either.Is -134F protection really needed?? ;-) In any case, even if anti-
freeze freezes it won=3Ft crack a block like water will. Water is
the only material that expands when it freezes.
Are you sure water is the only material? While I agree the vast
majority do shrink, I doubt water is the only one that expands instead.
I believe water is the only LIQUID that expands when it freezes.
I believe it=3Fs unique. Most chemicals/compounds are liquid under
some condition.
There are other materials that expand.
Example?
