FR-4700

FR-4700

Supports prepreg composite layout tooling for high-temperature applications up to 400F. Ideal for prototype machining, vacuum forming, pattern making and limited-run tooling.

Learn More

FR-6700

FR-6700

Flame-retardant foam for aircraft composite core withstands processing up to 250°F. Superb for models and design prototypes, vacuum-form dies and mold patterns, honeycomb edge closeout.

TR-Marine

TR-MARINE

Structural strength with moisture resistance offers boat designers a top-quality, non-decaying wood alternative that is fully compatible with fiberglass-laminating production methods.

Learn More

TF-5070

TF-5070

These flame-retardant foams offer comparable properties to the TF-6070 series, except that a slightly higher foam density would be needed under equal circumstances.

Learn More

TF-6070

TF-6070

These foams are designed for shock isolation of heavy objects when the supporting foam will be under long-term static stress.

Learn More

FP-8000

FP-8000

These open-cell polyurethane foams exhibit high hysteresis (approximately 80%) as well as excellent recovery from dynamic impacts.

Learn More

Foam-Comb

Foam-Comb Series

Our flame-retardant, flexible foam-filled Nomex® honeycomb material serves as a multi-purpose aerospace seal and filler.

Learn More

WSF-1010

WSF-1010 Series

This foam is ideal as a flexible seal where aesthetics are important. It can also be tinted and painted a variety of colors.

Learn More

WSF-1121

WSF-1121 Series

This is a tough integral-skin polyurethane foam system that can be pigmented and in-mold painted for a lasting finish.
