 VOLCLAY ® H P M - 2 0 Volclay® HPM-20 is a high-purity, air-classifed sodium bentonite that is selectively-mined. It consists of micronized particles and supplied as a free-fowing powder. This high-purity montmorillonite is typically used where small particle size is required for pesticide and fertilizer applications. Purity Hydrous aluminum silicate, air purifed to concentrate the fnest montmorillonite fraction from the bentonite ore. Contains traces of feldspar, quartz, calcite
