HDU (High-Density Urethane) board is a closed-cell, rigid urethane foam board that is commonly used in dimensional signs and tool making. It is available in grades that are stable up to 300° F.

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.

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.

Shop HDU from Grain Fraim and SignFoam in various densities, thicknesses, and sizes.

High Density Polyurethane (HDU) is tough, weather resistant and lightweight (15lbs/ft2). Its closed cell structure makes it completely waterproof which allows for the application of almost any paint finish. HDU can withstand all weather conditions and is ideal for the exterior applications including custom sign fabrication.

This proven, high-density urethane (HDU) foam board delivers exceptional versatility and outstanding value. Whether carved, routed, sandblasted or machined, it is ideal wherever a uniform, grain-free, dimensionally stable material is desired.

High Density Urethane is a “closed cell” rigid polyurethane product. It is made for utilizing it for temperatures of up to 200°F continuous exposure. Its density of 15 lbs./ft.3. It comes in custom sizes and thickness. It has a natural carved look and can withstand different weather conditions.

2021年5月16日 · High-Density-Urethane (HDU) is a rigid, “closed-cell” material. It is impervious to all petroleum-based solvents. Engineered specifically to make signs, HDU is waterproof and will not shrink or swell. As a result, it is easier to cut, route and manufacture, reducing the overall cost.

High-density urethane (HDU) board, produced from polyurethane, is a type of rigid foam board that boasts broad utility in diverse sectors, including signage production and tooling. Its wide range of applications can be attributed to its versatile properties and cost-effectiveness, which make it a highly coveted material in various industries.

HDU sandblasted foam signs are fabricated from open celled high density urethane (HDU). HDU foam signs are extremely versatile and the most reliable material for sandblasted signs. HDU foam can be sandblasted to look similar to wood grain, or with a pebble finish.
