Abstract

This invention relates to composite filtration media comprising (i) a functional filtration component and (ii) a matrix component, wherein said matrix component has a softening point temperature less than the softening point temperature of said functional filtration component, and wherein said functional filtration component is intimately bound to said matrix component;
and methods for preparing and using same. More particularly, this invention pertains to composite filter media and composite filter media products comprised of a functional filtration component, such as a biogenic silica product (e.g., diatomite) or a natural glass product (e.g., expanded perlite) which bears a distinguishing porous and intricate structure suitable for filtration, which is thermally sintered to a matrix component, such as an engineering polymer (e.g., glasses, crystalline minerals, thermoplastics, and metals) that has a softening temperature below that of the functional filtration component. The composite filtration media of the present invention offer unique properties such as increased permeability, low centrifuged wet density, low cristobalite content, and uniquely shaped particles (e.g., fibers).
