LAST-A-FOAM® FR-4530 is a rigid polyurethane foam board designed for tooling, pattern making, and composite applications. It has a density of 30 lb/ft³ (481 kg/m³), a compressive strength of 2,100 psi (14,500 kPa), a tensile strength of 1,500 psi (10,300 kPa), and a flexural strength of 2,100 psi (14,500 kPa), all measured at 75°F. Its maximum use temperature is 200°F (93°C), and the coefficient of thermal expansion is 29 x 10⁻⁶ in/in-°F (52 x 10⁻⁶ m/m-K). The material is representative of the FR-4500 series and is color-coded for density identification.
With a superior, fine-cell structure the high-density polyurethane FR-4500 allows for easy finishing with almost any coating system. This foam can also be bonded with a wide variety of adhesive systems. Available in densities up to 50 lbs per cubic foot, thus allowing users to match the right material to job requirements while controlling costs. Additionally, each density is color coded for easy identification. Its higher heat-deflection temperature rating makes it suitable for use in vacuum-forming applications where other urethane products may soften or deform.
