General Plastics Manufacturing Company offers unique open-celled flexible foams with engineered energy absorption properties. These foams allow users to design systems delivering good efficiency while absorbing energy at a consistent, controlled rate.

LAST-A-FOAM® high density flexible polyurethane foams are quite firm in relation to their density. They feature relatively flat static and dynamic stress versus deflection curves which allows these materials to absorb a great amount of impact energy without subjecting the equipment being protected to high stress levels.

LAST-A-FOAM® flexible and semi-flexible foams can be used in series or parallel to relieve static stress on flexible shock attenuation material, or to break up resonance or change shock pulse frequencies. Elevated temperatures have little effect on the performance of any of the LAST-A-FOAM® high density flexible foams with no long term effects up to 160°F and an approximate 10% reduction of firmness at the higher temperature. Reduced temperatures again have no long term effects, however, the foam can become significantly firmer at subzero temperatures. With the exception of intense UV radiation, LAST-A-FOAM® high density flexible foams are long lasting and relatively unharmed by environmental factors.
