Re: Hcrc 270
R-290 is propane
R-1270 is propylene
I have never heard of HCRC 270.

Re: Hcrc 270
Hello,
found this:
Now, just to add one more bit of info: each pure refrigerant can be
called either by its R-# (R-12), or by an appropriate prefix (CFC-12).
Thus, HFC-134a=R-134a, HCFC-141b=R-141b, and HC-270=R-270. Then, there
are also the chemical names. For instance, R-270 is known as propane.
The prefixes are an easy way to determine whether a refrigerant is an
ozone-depleter or not. If it's a CFC or HCFC, it is. If it's an HFC or
an HC, it's not. I'm not positive that HC is a standard prefix, but the
others are.
All of this, plus the safety classifications, is explained in Standard 34.

it seems that Brian_UK was right about propane
US Iceman, maybe you can find something more about Standard 34
Best regards

Re: Hcrc 270
HC-270=R-270...For instance, R-270 is known as propane.
I did find one source that may explain the confusion:
http://www.mipiggs.org/names_of_refrigerants.doc
Note: the columns in the refrigerant description are not labeled correctly, so you have to watch the comparison data closely.
R-270 is a propane derivative... cyclopropane
Hope that clears it up.
Some other info for further reading...

ASHRAE Standard 34 deals with refrigerant safety classifications and refrigerant purity I believe.
