Material Notes:

This foam polyurethane formulation is designed yield structural foam by either hand-mixing or machine casting method. The pot-life of this material is long enough to allow manual handling for cast-in-place application. It can also be used in molding short-run parts, and many other custom applications. The components are liquid at room temperature. The free-rise density of the foam is approximately 6.5 pounds-per-cubic-foot, the cell structure is closed-cell.Information provided by Northstar Polymers.
