NC Proofboard Performance
The tighter cell structure of the NC Proofboard 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.
Common Applications for High Density Urethane
Fast Turnaround on Custom Thicknesses
Because NC Proofboard 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 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 NC Proofboard LT 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 NC Proofboard LT, 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 NC Proofboard LT means that material cost can be managed according to application-specific performance requirements.
