Easy Cut and Shape for Pattern-Making

Our 2 lb./cubic foot Polyisocyanurate Foam Sheets are best suited for moldless pattern-making and for sandwich core applications where insulation is a factor. The properties of this foam are similar to those of our 2 lb. Mix and Pour Foam (#24/25), so it can be easily cut and shaped with a sharp knife or sandpaper.

  • Sheets are rigid and available in a variety of thicknesses.
  • Closed-cell structure resists oil, gasoline, and water absorption.
  • Glue sheets together to form thicker blocks for shaping functional, moldless parts.
  • Store unused foam away from direct sunlight to avoid degradation.
  • Temperature range: -300°F to 300°F


This item will typically ship in a large, rectangular box.


2 lb. Polyisocyanurate Foam Sheets All available thicknesses of foam sheets are sold by the unit, each containing three sheets (#440-C, #441-C, #442-C, and #443-C).
