Evaluation of 'Packcrest' Number 1008 Cushioning Material

Abstract

A new cushioning material concept, involving the combination of polystyrene beads with a matrix of polyurethane foam was evaluated to determine whether the union of these two materials would provide any synergistic benefits. The shock absorbing properties of the material was evaluated using standard dynamic cushioning tests. The test data, plotted in the form of peak acceleration versus static stress curves was compared with conventional polyurethane and polystyrene cushioning materials. The test results indicated that no significant improvement in shock absorbing properties was achieved by the combination of the two materials.
