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, mold-backing, and many other custom applications. The components are liquid at room temperature. The free-rise density of the foam is approximately 3.5 to 4.5 pounds-per-cubic-foot, the cell structure is more than 95% closed-cell. Part-A Component: MSE-021 (Prepolymer) Part-B Component: PPF-012 (Curing Agent ) Mixing Ratio: 1:1 = Part-A: Part-B by Volume (1: 0.858 by weight) Information provided by Northstar Polymers |
