High Density Urethane (HDU) Boards
Boards for hand-carved signs and CNC-machining
High density urethane foam board also known as HDU board is used for hand-carved signs as well as CNC-machining. RAKU® TOOL Styling Board (SB) has a fine surface structure and lends itself to both manual and mechanical processing. Precision Board Plus™ High Density Urethane (PBLT) is a “closed cell” rigid polyurethane product made specifically for applications of up to 200°F continuous exposure. High Density Urethane is available in a wide range of sheet sizes, thicknesses, and densities. It can be cut or bonded into a variety of shapes for final machining or shaping.
