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 also custom-formulate appropriate flexible foam systems to make the exact part you need. All of our flexible foams are intumescent and meet a variety of industry flammability requirements.

LAST-A-FOAM® rigid CFC-free polyurethane foam sheets, boards and products are cost-effective, versatile, strong and durable. They are American manufactured using our unique chemical formulas to be exceptionally uniform and consistent in all physical properties. You will find a wide spectrum of formulations in multiple densities. All of our rigid foams are “closed cell” and thus do not absorb water. These materials are available in sheets or blocks.

Our polyurethane foam sheets, blocks and mold forms are available in high density and flame-retardant versions. We have the ability to align HDU foam properties with your specific needs – and help you contain material and manufacturing costs. All of our rigid foams have excellent intumescent properties and meet a variety of industry flammability requirements.
