4 LB FLEXIBLE FOAM
TC-274 is a two-component water blown flexible polyurethane foam system. The cured material feels similar to a medium-firmness furniture cushion. BJB’s 6800 Series Pigments may be added to the “B” side for developing a wide range of colors. Common applications are prototypes, prosthetics, medical training devices, movie special effects props and more. This material is frequently molded behind BJB’s flexible polyurethanes. TC-274 can be hand mixed, machine dispensed, or mixed with a Jiffy Mixer®.
NOTE: Density is based off of free-rise, unrestricted samples. Typical castings in a closed mold with back pressure will increase density and reduce expansion rate. This will often require up to 1.5 to 2.5 times more foam than theoretical calculated amount of foam for a given volume and mold shape/goemetry. Also temperature of liquid foam, relative humidity, and mixing technique (hand stirred vs jiffy mix with a drill) will also affect expansion rate of foam.
