Attapulgite is a naturally occurring mineral that has distinct colloidal and sorptive properties due to its three-dimensional chain structure. It is a crystalline hydrated magnesium aluminum silicate. Attapulgite grades that are fully hydrated thicken liquids without swelling. Highly thermally activated grades combine high surface area with the porosity to optimize sorptivity. The Attapulgite thickeners effectively form thixotropic colloidal gels in ionic and non-ionic aqueous solutions. for more information visit: https://20nano.com/attapulgite-thixotropic-thickeners-and-rheology-modifiers/
