CNC and Modeling Foam (Polyurethane 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 prototyping applications. It can be sanded for beautiful results.
CORAFOAM® U polyurethane can be cut with almost any type of tool. Its closed cellular structure and absence of fibers or granular structure result in crisp, excellently defined edges after fabrication. The heart in the photo was cut with a kitchen knife and sanded.
It is also impermeable by any type of liquid, including water and solvents, making it much better suited for severe weather conditions or harsh marine environments than many other materials.
Please don't hesitate to send us a note if there are other sizes you would like.
We carry (2" and 4" thick for each). The higher the density, the firmer the foam.
High Density (HD):
4 lb/ft3 - tan
8 lb/ft3 - yellow
15 lb/ft3 - mint green
Low Density (LD) - light yellow in color, softer, looser - great for carving:
