The new Precision Board Plus High Density Urethane is made with certified Green “eco-friendly” urethane components and is the only board on the market with a certified “Carbon Balance” of 3 to 1 and “Rapidly Renewable Resource Content” of 11.9%. PBHT High Density Urethane is totally inert and contains no VOC’s, no carcinogens and is non-toxic. Precision Board Plus now assists in meeting LEED requirements for obtaining USGBC and ICC 700-2008 building credits. See Green Facts regarding PBHT.
The tighter cell structure of the new Precision Board Plus High Density Urethane foam board has produced improved machining characteristics, resulting in more chips and less dust during cutting and machining, making for a better working environment. Higher machine feed rates are easily achieved compared to wood, epoxy and alloy substrates. For more information take a look at our foam board comparison page.
Common Applications for High Density Urethane
- Prototype Machining
- Prepreg Composite Layup Tooling
- Vacuum Form Tooling
- Tool Proofing
- Pattern Making
- Master Model Making
- Soft Tooling – All Types
Fast Turnaround on Custom Thicknesses
Because Precision Board Plus High Density Urethane is manufactured in large blocks up to 20″ thick, they can be cut to produce sheets from 1/4″ to 20″ thick. As with density, the amount of raw material used to produce a given sheet size varies by thickness, so thickness selection can be made according to job specifications and material cost managed accordingly.

Choosing The Proper PBHT Density
Density is typically selected according to application or specific job requirements. The primary difference between various densities of our PBHT High Density Urethane is the thickness of the cell wall. The thicker the cell wall, the higher the density. The higher the density of Precision Board Plus PBHT, the stronger, tougher and heavier the product is. Density also directly relates to how much raw material is required to manufacture the product and therefore directly relates to its cost. The wide variety of densities available for PBHT means that material cost can be managed according to application-specific performance requirements. Refer to our High Density Urethane Material Selection Guide for help with product selection. If you need help with cutter selection, go to Onsrud’s Router Bit Search Tool and type in HDU.
