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. BIJB 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. 3# DENSITY 5# DENSITY eNO ENG AROEERUES For a soft resilient foam For an extremely soft foam : e A 50 parts A 30 Parts A Mix Ratio (by weight) 400 parts B 400 Parts B Density, (ree ise) se E Density, (free rise) kg/m? 80 Cream Time @ 77 F (25 C) 15-20 seconds 25-30 seconds Rise Time 75-90 seconds 90 100 seconds Demold Time @ 77 F (25 C) _ 5 7 E Depending on part size and cross section) 2030 minutes 20~ 30 minutes PARTA PART B Specie Graviy @ 77 @5 O) 1.02 Viscosity, (cps) @ 77 F (25 C) Brookfield 1200 *The density and processing times listed are derived from a statistical average of long-term testing.
