High Density Flexible Foam

General Plastics’ open-cell flexible polyurethane foams deliver efficiency while absorbing energy at a consistent, controlled rate. Our flexible foam sheets can be used in series or in parallel to relieve static stress on flexible shock-attenuation material. They can also break up resonance or change shock-pulse frequencies. Elevated temperatures have little effect on the performance of LAST-A-FOAM® flexible foams: There are no long-term effects up to 180°F, with an approximate 10% reduction of firmness at the higher temperature.

These flexible foams can withstand temperatures up to 160°F and reduced temperatures, although at subzero the foam can become significantly firmer.

LAST-A-FOAM flexible foam products are available as sheets, blocks and molded parts. We can assist in part design, tool design, mold-tooling manufacturing, and production of parts through all phases to completion. We also custom-formulate appropriate flexible foam systems to make the exact part you need.

LAST-A-FOAM© EF-4000 Series

FLEXIBLE FOAM SERIES Manufactured in densities of 3 to 7 lbs. per cubic foot, this series offers superior vibration isolation and cushioning for loads in the 0.1 to 2.0 psi static stress load range.

LAST-A-FOAM© TF 5070 Series

FLEXIBLE FOAM SERIES 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.


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


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

FOAM-COMB© Honeycomb Gap Seals

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