Northstar Polymers MPS-F04A Hand-Mixable Flexible Foam

This foam formulation is designed to make molded flexible foam parts/sheets/dies/blocks by hand-mixing or by the meter dispensing equipment. The components are stable liquid at room temperature and ambient pressure. It requires minimum tooling for a small production or short runs. These properties are ideal in small scale productions for custom foam applications such as custom seating, padding, and cushioning. Generally, lower density grade foams are softer than higher density foams. For firmer foam quality, 8 or 6 pound-per-cubic foot formulas are recommended. The free-rise density of the foam is 4.5 pounds per cubic foot, and the cell structure is designed to be open-cell. This is an MDI base water-blown polyester/polyether hybrid system, and it does not use flammable or ozone-layer-depleting auxiliary blowing agents. Examples for Applications: Molded Upholstery Parts Custom Seating, Padding, and Cushioning Parts Custom Packaging of Impact/Vibration-Sensitive Items Prototyping Information provided by Northstar Polymers.
