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. PBLT High Density Urethane is available in a wide range of standard sheet sizes and standard densities and can be cut or bonded into a variety of shapes for final machining or shaping.

Environmental Properties
The new Precision Board Plus High Density Urethane is made with Green “eco-friendly” urethane components and is the only product on the market with a documented, certified “Carbon Balance” of 3 to 1 and “Rapidly Renewable Resource Content” of 23.9%. Precision Board Plus PBLT is totally inert and contains no VOC’s, no carcinogens and is non-toxic. Precision Board Plus High Density Urethane now assists in meeting LEED requirements for obtaining USGBC and ICC 700-2008 building credits. See Green Facts.
PBLT Performance
The tighter cell structure of the new Precision Board Plus High Density Urethane 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 or alloy substrates. For more information take a look at our foam board comparison page.
Common Applications for High Density Urethane
- Prototype Machining
- Thermoforming

- Tool Proofing
- Master Model Making
- Pattern Making
- Soft Tooling-all types
- Indoor & Outdoor Signage
- Sculptures
- Carvings
Fast Turnaround on Custom Thicknesses
Because Precision Board Plus High Density Urethane is manufactured in large blocks up to 24″ thick, they can be cut to produce sheets from 1/4″ to 24″ 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.
Save time, material costs, and machining expense with our custom bonding service.
Choosing The Proper PBLT Density
Density is selected according to specific job requirements. The primary difference between densities is the thickness of the cell wall. The thicker the cell wall, the higher the density. The higher the density of Precision Board Plus PBLT, 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 Precision Board Plus PBLT 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.
