CNC and Modeling Foam (Rigid Polyurethane Foam) - High Density 4lb/ft3

High Density U40 CNC and Modeling Foam by Duna Our foam is perfect for 3D models with intricate shapes and layers using a CNC or hand shaping. It is hard to find in small sizes (our starting size is 12” x 12”when you would normally have to buy at least 4' x 4' or larger). It is dust-free, easy to sand and paint and more durable and attractive than Home Depot insulation foam.  High density CORAFOAM® (HDU) is an innovative polyurethane substrate used for a variety of applications in the signage, modeling, aerospace, composite, architectural and design industries. With its excellent workability, grain-free consistency (no dust) and broad range of densities, CORAFOAM® provides solutions to craftsmen and engineers alike. These characteristics, combined with polyurethane natural resistance to atmospheric agents, most solvents, and moisture, make CORAFOAM® polyurethane an ideal replacement for wood and other materials in signage, patternmaking, composite layup tooling, thermoforming, and prot
