tan powder??
Filter Aid, Celite AW Standard Supercel? is used for general filtrations. It is also used as a functional filler in paints, plastics, paper, rubber, adhesives, catalysts, agricultural chemicals, pharmaceuticals and other chemicals, and a mild abrasive in polishes and cleaners. It is also used in clarifying liquids and oils, as an efficient thermal insulator; in manufacture of heat insulators, fire brick, and fire- and acid-proof packing materials; as an absorbent; in absorbent dynamite; as a solid carrier in chromatography; pozzolanic admixture in concrete mixes.??
Diatomite: A whitish powdered mineral consisting mainly of silica (silicon( IV) oxide) derived from the shells of diatoms. It is used to make fireproof cements and as an absorbent in the manufacture of DYNAMITE.?? ??
Celpure? P65 (Diatomaceous earth, DE) is natural amorphous silica formed from the fossilized skeletons of diatoms. It is extracted, crushed, dried and calcined with or without flux material. DE is widely used as filler in construction materials, paints and as an anti-caking agent for agricultural chemicals. It has high water and oil absorption ability. The potential toxicity of different samples of DE has been assessed. DE is also employed as an adsorbent for column chromatography.???
Diatomaceous earth: Diatomaceous earth kills and repels insects, including bed bugs, fleas, cockroaches, and carpet beetles, by dehydrating them, rather than chemically poisoning them, and has been used since early times. It is also used as a filtering agent and as a filler in construction materials, pesticides, paints, and varnishes. The calcined version (which has been heat treated) is the most dangerous and contains crystallized silica, and should be handled as silica.???
