This foam polyurethane formulation is designed yield structural foam by either hand-mixing or machine casting method. The pot-life of this material is set longer than ordinary rigid foam formulations to allow enough handling time in a hand-mixing operation. Unlike common rigid foam formulation, the semi-rigid foam structure of MPP-M09D resists cracking and chipping from impact force by slight flexibility. This combination of features makes MPP-M09A ideal for cat-in-place foam application, molding compound for short-run parts, and many other custom applications. The components are liquid at room temperature. This can be batched manually by hand tools, and also be cast with a multi-component meter-mixing/dispensing machine. The free-rise density of the foam is 9 pounds-per-cubic-foot, the cell structure is closed-cell. Information provided by Northstar Polymers. |
