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.

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.
Self-skinning, FlexFoam‑iT!™ IV and 15 TUFF STUFF have a relatively high tear strength for a low-density foam. They are also stiffer and slightly harder to compress vs. other FlexFoam-iT!™ products.
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.
