ULTRALIGHT FLOWABLE MATERIALS AND ARTICLES OF MANUFACTURE INCLUDING SAME

摘要

An ultralight flowable material comprises a plurality of macrospheres having an average diameter of about 150 microns or above, and a lubricant. An amount of the lubricant in the ultralight flowable material is sufficient to substantially coat the exterior surfaces of essentially all macrospheres, but less than an amount to cause dispersion of the macrospheres in the lubricant. An article of manufacture includes a flexible container and an ultralight flowable material contained within the flexible container. The ultralight flowable material may comprise a plurality of spherical objects and a tacky lubricant in an amount to substantially coat the exterior surfaces of essentially all spherical objects but less than an amount to cause dispersion of the spherical objects in the tacky lubricant. The spherical objects comprise macrospheres, microspheres, or a combination thereof.

1. An ultralight flowable material, comprising:
a plurality of macrospheres having an average diameter of about 150 microns or above; and a lubricant in an amount substantially coating the exterior surfaces of essentially all macrospheres of the plurality and without causing dispersion of the plurality of macrospheres in the lubricant; wherein the ultralight flowable material has a specific gravity of 0.17 or less.
