Flexible Foams

LAST-A-FOAM® WSF Series high-density polyurethane flexible foams are flame-retardant, durable and self-skinning (also known as integral-skin foams). They are ideal for use in aircraft flight decks and cabins and other applications requiring durable, fire-resistant padded parts.

Open-cell WSF-1010 and WSF-1121 products are used by aerospace manufacturers for molded and fabricated flight-deck padding and aircraft interior parts. These self-extinguishing, flexible urethane foams can be custom-molded to your exacting specifications. All of our flexible foams are intumescent and meet a variety of industry flammability requirements.

We can assist in part design, tool design, mold-tooling manufacturing, and production of parts through all phases to completion.

PLEASE NOTE: The WSF foam series is not offered for sale as liquid kits or sheet stock. It is only available within a finished parts program.
