Biscuit Foam is a polyurethane foam. The BF range comes in various densities making them suitable for many different applications, ranging from super light weight to very dense, high strength foams.
The number indicated in the Biscuit Foam range represents how many LBs of material it takes to fill a cubic foot. This varies due to higher/lower foam expansions.
Biscuit Foam 2 (also known as BF2) takes 2LBs of material to fill a cubic foot.
