Thermoformable Foam
LAST-A-FOAM® FR-4300 THERMOFORMABLE BOARD SERIES
General Plastics’ LAST-A-FOAM® FR-4300 thermoformable foam sheet series is a unique low density, flame-retardant structural polyurethane foam. It is ideal 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 foam boards. A closed-cell material, it is easily bonded and will accept a variety of adhesives and coatings. This series is non-abrasive and can be machined with standard high-speed steel (HSS) cutting tools. It can also be cut cleanly with water jets and traditional wood-carving tools.
Advantages
- Retains polyurethane foam’s chemical and solvent properties under heat
- Accommodates low-cost heat-forming methods
- Bonds easily
- Accepts variety of adhesives and coatings
- Max use temperature of 200°F (93°C)
Applications
- Composite panel cores
- Detailed structures and compound-curved surfaces
