4lb Corafoam / Dunaboard U40 Medium Blocks

High density CORAFOAM® (HDU) is an innovative polyurethane substrate used for a variety of applications in the signage, theming and modeling in aerospace, composite, architectural and design industries. With its excellent workability, grain-free consistency and broad range of densities (4 lb/ft3 through 31 lb/ft3), 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.

Additionally, it’s resistance to mechanical stress and exceptional insulating qualities have proven it a valuable asset as a support in the cryogenic field
