Why are you a communist sympathizer? |
I was unaware that CFCs were presently in production after the late 1980s.It was supposed to be a global ban and phase-out.The internet said nothing about recent manufacture.Carbon dioxide has been available as a blowing agent for polyurethane/polyisocyanurate foams for 30-years,and it's cheaper than FREON.
