Anbody heard of this product? They claim you can put this foam in closed wall cavities, including partially insulated ones. I’m extremely skeptical, but couldn’t find any third-party info.

This looks a lot like RetroFoam, which is another injectable foam product. And it looks like they use formaldehyde in their formula, at least according to the spec sheet on their website:
"Formaldehyde Content of Cured Foam
Less than 50ppb formaldehyde emitted per ASTM D-5116 (Small Chamber)"
I'm sure others on this forum will be able to give you more of the ins and outs of this type of product. I do know that if not installed properly, shrinkage can be a big issue with these types of products.
