...Demilec and Elastochem. The GWP (Global Warming Potential) of the standard HFC blowing agents was as high as 1,430, where the GWP of the new HFO blowing agents is only 1, meaning that HFO blowing agents are on par with Carbon in terms of the climate change impact rather than being 1,430 times worse.
I would also wonder...
