LAST-A-FOAM™ FR-7130 is a rigid polyurethane foam with a density of 30 lbs/ft³ (481 kg/m³), designed for structural core applications in composites, tooling, and marine systems. It has a compressive strength of 2,370 psi (16,300 kPa), tensile strength of 1,400 psi (9,700 kPa), shear strength of 1,940 psi (8,800 kPa), and flexural strength of 13,400 kPa (1,940 psi), all measured parallel to the direction of rise. The maximum continuous use temperature is 220°F (104°C), and its coefficient of thermal expansion is 31 × 10⁻⁶ in/in-°F (56 × 10⁻⁶ m/m-K). The material is available in block form with a fine closed-cell structure, suitable for machining and bonding.
This polyurethane foam is great for applications where an economical, versatile, and stable stock material is desired.
LAST-A-FOAM® FR-7100 can be used with multiple densities. There can be high and low densities in one layup, making it an ideal material for composite layups. In addition, this product is available in sheet stock and there is no mold-release in GP's sheet stock manufacturing process.
LAST-A-FOAM® FR-7100 is formulated to meet the demands of composite boat builders at competitive prices. For Stringers, we recommend the FR-7100 in 6-20 lb per cubic foot densities depending on structural need. For seat mounting pads and steering wheel mounting, we recommend 24-30 lb per cubic foot densities. Lastly, for decks and bulkheads, we recommend 10-15 lb densities of the FR-7100 foam.
LAST-A-FOAM® FR-7100 is an economical polyurethane foam made in 4-40 lb densities. This foam is suitable for hand-carved models, CNC-machined topographical maps, prototypes, industrial patterns, and more. FR-7100 is made in more densities than any other product we offer and large block sizes are available.
LAST-A-FOAM® FR-7100 products have been used sucessfully in tooling applications for many years. This material meets the needs of mold and tool makers because of it's stress free, easy to machine, and has constant density throughout thickness. Generally speaking, if higher strength, greater detail, or increased heat and pressure resistance at process tempeature is rquired, the FR-7100 performs best at a 20 lb per cubic foot density. Typical uses include: composite lay-up tools, drape-forming tools, and vacuum-form tools.
