    FR-3700 PERFORMANCE CORE SERIES
    Flame-Retardant Polyurethane Foam
    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 foam
    particularly supports the following industries:
    Aerospace
    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.
    Medical
    High-density rigid polyurethane FR-3700 foam is used to simulate human bone as a test medium within the medical device industry.
    Nuclear
    FR-3700 foams are chosen for nuclear material applications and transportation of extremely hazardous waste. When used as an impact- and fire-insulation liner in transport containers, FR-3700 can be engineered to provide the ultimate in fire and collision protection for hazardous cargo, outperforming wood and other polymeric materials. The FR-3700 formulation is specially designed to allow predictable impact-absorption performance under dynamic loading. At the same time, it provides an intumescent char layer that insulates and protects hazardous materials, even when exposed to pool-fire conditions.
    In particular, our FR-3700 foam has a solid history of successful use in radioactive materials (RAM) transportation packages. The regulations governing RAM packages often require energy absorption of 30-foot free drops and exposure to a 1,475°F, 30-minute fire under accident conditions. Our FR-3700 series foam is one of very few materials that can support the RAM package design in mitigating both mechanical and thermal energy.
