One (1) Smooth-On Flex Foam-iT Gallon Kits

FlexFoam-iT!™ expanding flexible foams are easy to use and durable. They are lightweight, versatile and most are available in easy to measure mix ratios. They can be used for padding/cushion material, gasket material, or to make props and special effects. Vibrant colors can be achieved by adding color pigments.


FlexFoam-iT! ® flexible polyurethane foams come in a broad selection of formulations from a 3 pound to a 25 pound density and many others in between. This means you can choose between a high 15 times expansion rate to as low as 2 times expansion to meet your project needs.

FlexFoam-iT!™ 6 and VIII
Pillow Soft

These foams are very soft and are used for padding/cushion, specialty bed, and orthopedic pillow material applications. Cured foam has very good physical and rebound properties.

FlexFoam-iT!™ IV
