Solid Rigid Polyurethane Foam
Solid rigid polyurethane foam provides a uniform structure with only +/-10% variation in density. Material properties cover a broad range of human bone qualities allowing you to select an appropriate density for your study. This closed cell foam conforms to ASTM F-1839-08 “Standard Specification for Rigid Polyurethane Foam for Use as a Standard Material for Testing Orthopaedic Devices and Instruments” and has the largest density range available from 0.08g/cc up to 0.80g/cc (5pcf to 50pcf).
For more information see our Biomechanical Products Catalog and Biomechanical Validation Studies page.
Our foam is available in a range of sizes and densities, f rom 0.08 to 0.80 grams per cubic centimeter (5 to 50 pounds per cubic foot).
Cellular Rigid Polyurethane Foam
Cellular rigid polyurethane foam has larger pores to resemble cancellous bone. Cell size ranges from 0.5 to 2.0mm diameter for this primarily closed cell foam. Variation in foam density is ± 10% and is available in a range of densities from 0.12g/cc to 0.32 g/cc (7.5pcf to 20pcf).
For more information see our Biomechanical Products Catalog and Biomechanical Validation Studies page.
BLOCK SIZE: 13 cm x 18 cm x 4 cm
Open Cell Rigid Foam
Open cell rigid foam is a composite foam made of urethanes, epoxies and structural fillers. Cell size ranges from 1.5 to 2.5mm in diameter and is more variable than solid or cellular polyurethane foams. Variation in foam density is ±10% and is available in a range of densities from 0.12g/cc to 0.48 g/cc (7.5pcf to 30pcf).
Note: 30pcf open cell foam contains both closed and open cell walls.

Composite Sheets (Short Fiber Filled Epoxy)
Sawbones’ unique epoxy formulation is filled with short glass fibers and used to simulate cortical bone for structural testing of fixation devices and total joint replacements. Our simulated cortical bone has a density, fracture toughness, strength, modulus and hardness all similar to cadaveric cortical bone.
This material is the cortical bone for all our composite bones - Shop Composite Bones.
