FlexFoam-iT!® 17 is a 17 lb/cubic ft. (270 kg/m3) flexible urethane foam that is ideal for a variety of art and industrial applications. Like the popular FlexFoam-iT® 25, the 17 is "self-skinning", meaning that the cured foam forms continuous high density skin. With the right amount of back pressure applied during casting, the surface finish of the cured foam approaches that of a urethane elastomer.
The mix ratio is a convenient 1A:2B by volume. Pot life is 60 seconds and handling time is about 30 minutes at room temperature. Cured foam is strong, bendable and tear resistant.
The foam is easily colored with So-Strong® color tints or Ignite® fluorescent pigments and is compatible with Smooth-On's cast magic system for creating a variety of finish effects. The foam can also be painted with flexible paints.
Applications for FlexFoam-iT!® 17 include making lightweight, durable props and display pieces, special effects and arts/crafts.
Urban Fox Studios was contracted to make flexible foam motorcyle engine display props for a themed restaurant environment. Required: finished props needed to look exactly like a motorcycle engine. The display pieces would be "child" high and therefore needed to be soft for safety, and durable to resist wear and tear.
