- Closed Cell Structure- Won’t absorb anything
- Easily cut or machined with standard cutting tools
- Meets flammability burn test requirements of ASTM D-1692-74, Far 25.853, Mil-P-26514 & ASTM D635
Environmental Properties
The new Precision Board Plus PBHT formulation is made with certified Green “eco-friendly” urethane components and is the only product on the market with a certified “Carbon Balance” of 3 to 1 and “Rapidly Renewable Resource Content” of 11.9%. Precision Board Plus PBHT 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.
Product Performance
The tighter cell structure of the new Precision Board Plus PBHT formulation 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.
Common Applications
- Prototype Machining
- Thermoforming
- Prepreg Composite Layup Tooling
- Vacuum Form Tooling
- Tool Proofing
- Pattern Making
- Master Model Making
- Soft Tooling – All Types
Fast Turnaround on Sheets cut to your specified thickness
Because Precision Board Plus PBHT 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 PBLT Density
Density is typically selected according to application or 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 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 Precision Board Plus PBHT means that material cost can be managed according to application-specific performance requirements.
