I'm looking for information about substitutes for methylene chloride as
a blowing agent for foam. Perhaps CO2. (NOT trichlorethylene). I'm
curious of anything is out there on either a research scale or better
yet, commercial scale. Isn't the blowing agent use of methylene
chloride much more environmentally significant than its use as a cleaner
(either for the mixing chamber or the delivery tip?) Tnaks.
