| Solid Rigid Polyurethane Foam Primary Use
Solid rigid polyurethane foam is primarily used as an alternative test medium for human cancellous bone. These products are not intended to replicate the mechanical properties of human bone, however, it does provide consistent and uniform material with properties in the range of human cancellous bone. Relevant mechanical properties for comparison to human cancellous bone may depend on the particular test method that is being developed.
The ASTM F-1839-08 "Standard Specification for Rigid Polyurethane Foam for Use as a Standard Material for Testing Orthopaedic Devices and Instruments" states that, "The uniformity and consistent properties of rigid polyurethane foam make it an ideal material for comparative testing of bones screws and other medical devices and instruments."
Description
Solid rigid polyurethane foam has a closed cell content ranging from 96.0 to 99.9%. Foam is available in a range of sizes and densities, from 0.08 to 0.80 grams per cubic centimeter (5 to 50 pounds per cubic foot).
.
Standard block size: 13cm X 18cm X 4cm
Standard sheet size: 13cm X 18cm X 3mm
Other Notes
Water absorption ranges from 0.301 to 0.0 kg/m2
Foam meets ASTM F-1839-08. Block dimensions are within ±2mm and sheet thickness is within ±0.3mm. Foam density may vary ±10%.
