First post and some info I've found, also wondering about Suppliers.

Hi goneagain,

Their listed compression modulus is one of the reasons I don’t think they know much about what they are selling. 1.9 is typically the compression modulus of lower quality conventional foam not HR foam in higher densities. Higher densities can also be achieved by adding fillers or fire retardant materials to a foam which leads to a higher listed density than the polymer density of the foam.

You can see a brief description of it in post #2 here. It would depend on its density and on whether it was qualux or qualux ultra. It’s just polyfoam not inherently healthier, safer, cleaner, less allergenic, or better for the environment than any other polyfoam although there is a range of polyfoam materials that have different formulations and a wide range of quality…

I don’t think there is a single direction and this question would probably need a book to answer. Overall … probably more specialty foams and combination or hybrid types of polymer materials with enhanced properties of various types.

Just for reference … FBM doesn’t make foam. They just buy it and re-sell it.
