LAST-A-FOAMŪ TF-5070-series flexible high-density polyurethane foams are formulated to absorb large amounts of energy while protecting payloads from high stress levels. These polyether formulations exhibit great durability and resistance to environmental factors while maintaining consistent performance. LAST-A-FOAMŪ TF-5070-series foams are available in several types and densities, many of them relatively flame-resistant.
LAST-A-FOAMŪ TF-5070-series foam is available in 9 to 15 lbs/cubic foot density. Each of these foams demonstrate relatively "flat" load-deflection curves, which means they absorb energy while exposing delicate parts to consistent lower-level stresses.
In aerospace applications LAST-A-FOAMŪ TF-5070-series and EF-4000 foams have both been used extensively as "spring-damper" shock isolation systems to protect missiles in underground silos and nuclear submarine launch tubes. Minuteman, Peacekeeper, and Trident programs all have used these foams.
In construction applications, LAST-A-FOAMŪ TF-5070 foams have been used as shock-isolation systems for earthquake-prone buildings and vibration-damper pads for mechanical equipment.
A related product, LAST-A-FOAMŪ TF-6070, is available for those applications where flame-retardant foam is not required. This material has slightly different physical property and performance characteristics (when compared to TF-5070). Please contact General Plastics Manufacturing Company for more details on this foam product.
