Easy Carve for More Detailed Patterns and Molds

Our 6 lb./cubic foot Polyisocyanurate Foam is a rigid, closed-cell foam used in insulation, sandwich core, and carving applications where strength is key. The properties of this foam are similar to those of our 6 lb. Mix and Pour Foam (#624/625), so it can be easily cut and shaped with a sharp knife or sandpaper, and its density is suited to hold greater details.

Glue sheets together to form thicker blocks for shaping functional, moldless parts.
Store unused foam away from direct sunlight to avoid degradation.
Temperature range: -297°F to 300°F
