Northstar Polymers FFM-1 Firm-Grade Flexible Open-Cell Foam
Categories: Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced

Material Notes: This foam formulation is particularly designed to make flexible but firm open-cell foam by either hand-mixing or machine casting. This material may be suitable for products that require some load bearing property but need to be flexible. The firmness of this material is similar to that of microcellular foams, but it is lighter than microcellular foams. This material may also be suitable for some bumper or vibration dampening parts.

The components are liquid at room temperature. It has relatively long pot life (40 – 45 seconds) for a flexible foam material, so it is easier to handle by a manual hand-mixing method. This material can be open-cast into a slab for farther fabrication or molded in a compression mold. The free-rise density of the foam is 8 pounds per cubic foot, and the cell structure is open-cell.

The isocyanate component for this formulation is MDI, which is generally considered safer than TDI. This formulation does not use auxiliary blowing agent such as Freon, HCFC, CFC, or flammable hydrocarbon materials. Only normal handling for typical industrial chemicals is required. Relatively safe and easy handling and the physical properties of this foam satisfy the requirements for a variety of custom applications.
