Abstract
A material for use in resilient conforming pads, cushions and the like and cushions filled with such material as described. The material comprises elastic gas-filled hollow microparticles cohered to a mass by a thermoplastic bonding agent semi-liquid at body temperature. The material is useful for providing contour-conforming resilient padding for garments, athletic equipment, prosthetic devices, surgical or vehicular cushions and the like. The gas-filled hollow particles each have a resilient gas-impermeable thermoplastic shell enclosing a quantity of a gas.
