Flexible Foam Systems

MPA-F03A is designed to make molded flexible foam parts/sheets/dies/blocks. A small quantity may possibly be processed manually. The components are low-viscosity stable liquid at room temperature. The free-rise density of the foam is approximately 3.3 pounds per cubic foot. The cell structure is mostly open-cell. It is recommended to physically crushing soon after foam is made to stabilize the molded shape. This is an MDI base water-blown polyether system, and it does not use auxiliary blowing agents

MPP-F07A is designed to make molded flexible foam parts/sheets/dies/blocks by hand-mixing with very basic tools such as a cup and stir stick. The components are low viscosity stable liquid at room temperature. These properties are ideal in small scale productions for custom foam applications such as custom seating, padding, cushioning, many others. The free-rise density of the foam is 6 to 7 pounds per cubic foot. The cell structure is partially open-cell, and may be made to open-cell structure by physically crushing soon after foam is made. This is an MDI base water-blown polyether system, and it does not use auxiliary blowing agents.

VEF-121 is polyurethane open-cell flexible foam with viscoelastic property for a variety of cushioning and other custom applications. The cured foam has a very low deflection against a compression force. Foam recovers slowly after load is removed. The foam stays flexible at very lower temperature. The component materials are low viscosity liquid at room temperature. The pot-life is above 25 seconds, which allows small amounts to be batched manually. VEF-121 provides a range of foam consistency to be adjusted by varying the mixing ratio between the part-A/ part-B components. The recommended mixing ratio range is between 100:260 and 100:300 = part-A: part-B by weight. A higher part-B ratio makes foam with slower recovery rate and smaller compression deflection. This set of properties makes VEF-121 a more user-friendly viscoelastic foam formulation material for manufacturers of specialty products, product designers, and prototype makers.

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 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 8.5 pounds per cubic foot, and the cell structure is mostly open-cell.
