Demilic, BASF, Lapolla, etc have all phased out CFC-11 in their Open and Closed Cell Foams since around 2009. It's not surprising that the Chinese still use the old style spray foam. It was less costly to produce, had better cell structure and a better rise from what I remember. But not so good for the environment. The only positive is where ever they use it as insulation, will reduce energy needs to heat or cool the structure.
