Description
Last-A-Foam® FR-3740 is a CFC-free, closed-cell, flame-retardant rigid polyurethane foam from the FR-3700 Performance Core series. With a density of 40 lb/ft³, it has enhanced compressive and mechanical strength while maintaining a favorable strength-to-weight ratio. Its cross-linked cellular structure provides low water absorption and excellent machinability for demanding structural and tooling applications.
