Last-A-Foam 4.5Lb 3/8X48X96

FR-3700 meets the requirements of aircraft BMS 8-133. This rigid, polyurethane foam is comparable to the FR-6700 in strength, temperature resistance and flammability performance. However, the FR-3700 is tougher (less friable) for cutting crisper edges.FR-3700 is a CFC-free, rigid, closed-cell, flame-retardant polyurethane foam available in densities ranging from 3 to 40 pounds per cubic foot. It exhibits a high strength-to-weight ratio due to its cellular structure and cross-linked resin. Because of its closed-cell structure, LAST-A-FOAM® FR-3700 has great resistance to water absorption, and will not swell, crack, or split on exposure to water. 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. This flame-retardant polyurethane (PU) foam particularly supports the following industries.
