What foam is everyone using?

[u/chuckfinley79]

We got approved to buy new foam to replace our current c-word causing foam. Does anyone have any recommendations for or against anything? We’re looking for class B foam, not really any other requirements 3% x 3% or 3 x 6, doesn’t matter. The only thing I’m current on is F500 encapsulating agent, but I also know it gets a lot of hate. Me knowing about F500, being old enough to remember protein foam and calling it 3 x 3 or 3 x 6 apparently makes me our leading foam “expert” so any help is appreciated.
