LAST-A-FOAM® FR-4300 heat-formable foam is unique flame-retardant structural polyurethane foam. It is intended for composite panel cores and other structures where compound-curved surfaces or other details can be made with low-cost heat-forming methods. While it is heat-formable, it retains all the chemical and solvent-resistant properties of polyurethane foams. A closed-cell material, it is easily bonded and will accept a variety of adhesives and coatings. LAST-A-FOAM® FR-4300 Heat-Formable Foam contains no chlorofluorocarbons.
LAST-A-FOAM® FR-4300 Heat-Formable Foam is available in 5-, 10, and 15lb. densities, and in sheet-sizes up to 48" x 96". For more information, please see the FR-4300 Material Safety Data Sheet and the Technical Data Sheets for specific densities.
