  • Patent number: 6197099
    Abstract: A composite mixture of spherical objects and lubricant useful for its cushioning properties is disclosed and claimed. The composite mixture may be composed of microspheres typically less than 2000 microns in diameter with inert atmospheres sealed within their interiors and any of a variety of lubricants facilitating sliding and rolling movement between microspheres. Typically the composite mixture includes lubricant in a quantity sufficient to substantially coat the exterior surface of essentially all of the spherical objects, but in a quantity less than would cause dispersion of the spherical objects in the lubricant sufficient to physically separate the spherical objects from each other and substantially reduce the sliding and rolling contact of the spherical objects with each other. The preferred lubricant is a visco-elastic fluid that has a principle molecule and a cross-linking agent.
