Evaluation of a Polyurethane/Polystyrene Composite Cushioning Material,

Abstract

An evaluation of a polyurethane/polystyrene composite cushioning material revealed that the dynamic cushioning characteristics of this material has a broader static stress range, for a specific peak acceleration, than some of the existing 2 pcf materials listed in the Military Handbook 304A, 'Package Cushioning Design'. Samples of materials identified as structural grade and cushioning grade together with intermediate grades of material formulations, were analyzed to determine the effect of the expanded polystyrene beads in the material formulation.
