TC-284 A/B is a two-component, self-skinning, flexible polyurethane foam. The cured material feels similar to an auto arm rest pad. 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, bumper/crash pads, arm rests, movie special effects props and more. Skin thickness is controlled by material/ mold temperature, and the loading of the mold. Note: TC-284 at a ratio of 50/100 is a firm, 8 lb. density foam. At 30/100 ratio, the result will be a softer feel but the density increases to 13 lbs. per cubic foot.
