TC-277 A/B ‘PolySoft 3’ is a two-component, flexible polyurethane foam. The cured material feels similar to foam sandals. BJB’s 6800 Series Pigments may be added to the “B” side for developing a wide range of colors. End users can adjust firmness with a slight ratio change as listed below. Common applications are prototypes, prosthetics, medical training devices, movie special effects props and more. This material is frequently molded behind flexible polyurethane skin materials such as BJB’s SkinFlex line or other BJB elastomers.
Note: TC-277 ‘PolySoft 3’ at a ratio of 75/100 pbw produces a firm, quick recovery foam. At 60/100 pbw, the result will be a slightly softer foam.
Note: For best results using self-skinning foams, BJB recommends using rigid mold materials like our TC-1630 and TC-1650/1651 instead of silicone molds.
