Abstract
A foam material includes the reaction product of a polyol mixture and an isocyanate mixture and a boron nitride filer in an amount of ≥ 0.01 wt. % to ≤ 0.1 wt. %. In various forms, the boron nitride filer is of nanoparticles, is of hexagonal boron nitride, and/or is treated with a silane coupling agent.
