Dense and low expansion
I am used to working with 3lb foam and wanted to try a 4lb foam for a project that needed some extra stiffness. This product didn't disappoint. The volume of foam that it made wasn't as much as a lighter density, but it set off and hardened extremely quickly. I was able to do my project quickly and get it out of the way. Thanks for making it easy.
