- I have contacted DuPont and Bayer on that topic, since we are
- *strongly* interested in drop-in replacements for CFCs
-
- From what I heard I understand that the acute toxicity as well as the
- subacute long-term toxicity is too high to allow HFC-134a to be used
- in industrial processes.
-
- If anybody has different information on that, I really would be happy
- to hear more about it.
