This formulation is designed to make molded flexible foam parts/sheets/dies/blocks by a hand-mixing method with basic manual tools. The components are low-viscosity stable liquid at room temperature. The pot life is approximately 30 seconds, which is relatively long for this class foam formulation. These properties are ideal in small-scale productions for custom foam applications such as custom seating, padding, cushioning, many others. Comparing to our 7-pound-per-cubic-foot density foam, MPP-F07A, flexible foam made of MPP-F04C exhibits a more gradual compression deflection pattern to provide a softer feel. The component mixing ratio may also be adjusted to yield softer foam. The free-rise density of the foam is 4.15 pounds per cubic foot. The cell structure is open-cell with partial closed-cell. The molded foam may need to be physically crushed after the foam is demolded to ensure a fully open-celled structure. This formulation is an MDI base water-blown polyether system, and it does not use ozone-depleting auxiliary blowing agents. Examples for Applications: - Molded Upholstery Parts
- Custom Seating, Padding, and Cushioning Parts
- Custom Packaging of Impact/Vibration-Sensitive Items
- Acoustic Foam Pads
- Prototyping
