HDU
High Density Urethane (HDU) Boards. High density urethane foam board also known as HDU board is used for signage and architectural models, and is extremely versatile. The closed cell structure of HDU resists absorption, cracking, rotting and peeling, and lasts much longer than wood. High density urethane is available in a range of sheet sizes, thicknesses and densities, and can be cut or bonded into a variety of shapes for final machining or shaping.
