Density 20lb/ft3. High density polyurethane rigid foam. DUNA-USA 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. 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.
