General Plastics LAST-A-FOAM® FR-4520 High Density, Rigid Foam
Categories:	Other Engineering Material
Material Notes:	Product Description: LAST-A-FOAM® high-density, rigid foam products are cost-effective, versatile, strong and durable. They are manufactured using our unique chemical formulas to be exceptionally uniform and consistent in all physical properties. The FR-4500 is a grain-free, machineable tooling board for styling and design models, master models, masters for composite and layup tools, and for mold and foundry patterns. The material also serves as an excellent wood alternative for outdoor signage and display manufacturing. Available in densities from 10 to 50 lbs. per cubic foot. Key Performance Benefits: Special formulation creates shavings when material is machined, causing less dust Excellent consistency and uniformity throughout entire mass of material Dimensional stability No warp or bow in sheets Large sheets (up to 48” x 96”), thick sheets (up to 22”) available Custom sizes available Applications: Design prototypes Appearance or “sight” models Styling models Architectural models Master models Temporary models Trim, jigs, and fixtures Thermoforming tools Prototype foundry patterns Mold patterns Topographical maps Dimensional check-fixtures Molds for low-temperature casting (<200 ºF) Prototype/low-volume Vacuum-forming tools CAD model proofs/NC program proofs Tooling aids Molds for low-temperature curing prepregs (<200 ºF) Information provided by General Plastics Manufacturing Company
