FR-3700 is available in densities up to 40 lbs per cubic Ft. For more information please see the FR-3700 Material Safety Data Sheet (MSDS) and Tech Data Sheet (TDS) for specific densities.
Aerospace
LAST-A-FOAM® FR-3700 meets the requirements of aircraft BMS8:133. 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) so you can cut crisper edges. It is available in lower densities of 3 to 9 pounds per cubic foot as well as in 30- and 40-lb densities.
Artificial Human Bone Test Media
High-density rigid polyurethane LAST-A-FOAM® FR-3700 is used as a test media for the medical field. It is used to simulate human bone.
Nuclear
LAST-A-FOAM® FR-3700 foams are high-performance materials intended primarily for applications in nuclear materials and extremely hazardous waste transportation. When used as an impact-and-fire insulation liner in transport containers, FR-3700 can be engineered to provide the ultimate in 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, while also providing an intumescent char layer that insulates and protects hazardous materials, even when exposed to pool-fire conditions.
