Attapulgite, a naturally occurring mineral, is a crystalline hydrated magnesium alumino silicate with a three dimensional chain structure that gives it unique colloidal and sorptive properties. Fully hydrated attapulgite grades thickens liquids without swelling. Highly thermally activated grades combine high surface area with porosity to optimize sorptivity.
The Attapulgite thickeners effectively form thixotropic colloidal gels in ionic and non-ionic aqueous solutions. They also develop thixotropic gels in most organic liquids to develop thickening and/or suspension properties when dispersed with various cationic or non-ionic surfactants. All Attapulgite products provide thixotropic viscosity in liquid systems and are not impacted by extreme changes in pH or temperatures. Contrary to many commercial thickeners, the Attapulgite products are able to build viscosity in the presence of very high salt concentrations.
