POLYSOFT 1 RoHS
3-5 Ib. VARIABLE DENSITY, FLEXIBLE FOAM
TC-266 A/B PolySoft 1 is a two-component, flexible polyurethane foam. The cured material feels similar to a soft furniture cushion.
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 FP, F, M, and L line or
other BJB elastomers.
Note: TC-266 at a ratio of 50/100 pbw produces a soft, quick recovery foam with a density of 3 pounds. At 30/100 pbw, the result
will be a softer, slower recovery foam with a density of 5 pounds.
