Abstract
Fire retardant polystyrene insulating material is manufactured from expandable polystyrene beads in admixture with a phenol-formaldehyde or melamine-formaldehyde resin in resole form, the resin containing a blowing agent and a surfactant. The insulating material is formed from the bead-resin mix by applying dielectric heating to foam the resin, expand the beads, and cure the foamed resin to a closed cell structure.
