Home - Celatom® Diatomaceous Earth Product Portfolio | RBH Ltd Celatom® Diatomaceous Earth Range of diatomaceous earth (DE) functional minerals for filtration, filler, absorbent, carrier and performance additive applications across industrial, coatings, environmental and speciality liquid systems. CAS NUMBER: 61790-53-2 Request A Sample Names Diatomaceous Earth|DE|Kieselguhr Chemical formula SiO₂·nH₂O Product Overview Celatom® Diatomaceous Earth is a broad range of natural and flux-calcined diatomite products based on highly porous skeletal remains of freshwater diatoms. These grades are engineered to provide controlled porosity, high surface area and inert behaviour for demanding applications requiring filtration performance, filler functionality, fluid suspension aid, absorbency, carrier support and surface modification. The Celatom® range includes multiple grade families tailored to differing industrial demands: Mineral Natural (MN) grades provide natural DE with high purity for filler and carrier roles; Filter Natural (FN) grades are low crystalline silica, low permeability products optimised for fine filtration; Filter Pink (FP) grades deliver enhanced permeability performance for specific polish and industrial filter applications; Filter White (FW) grades offer a wide range of permeability for broad filtration control; Mineral White (MW) grades supply flux-calcined DE with enhanced brightness, opacity and multi-function additive behaviour for coatings, plastics, adhesives, rubbers and speciality liquid applications. Across the range, Celatom® products combine natural silica structures with variable porosity and particle size characteristics, enabling formulators to achieve effective liquid clarification, carrier function, friction control, anti-caking, bulk stability, and rheological influence in both aqueous and non-aqueous systems.
