Attapulgite
Attapulgite is a kind of crystalloid hydrous magnesium-aluminum silicate mineral, having a special laminated chain structure in which there is a crystalline lattice displacement existed. Thus it makes the crystals contain uncertain quantities of Na+, Ca+, Fe3+ and Al, and present in the shape of needles, fibers or fibrous clusters. Attapulgite has very good colloidal properties such as: specific features in dispersion, high temperature endurance, salt and alkali resistance, and also high adsorbing and de-coloring capabilities. Furthermore, Attapulgite has certain plastic and adhesive characters. Its ideal molecular formula is: Mg5Si8O20(HO)2(OH2)4 4H2O.

Drilling
MegaGel-30 Grade Attapulgite clays are swellable clays like Bentonite, although more are in needle shape. MegaGel-30 Grade Attapulgite, unlike Bentonite, will swell in salt water and is used in special salt water drilling mud for off shore oil drilling. Like many clays, they can be considered as charged particles with zones of + and - charges. MegaGel-30 Grade Attapulgite clays are agglomerated bundles of clay particles between 20 and 100 micrometers long and below 1 micrometer in diameter. Most grades contain up to 25% non-Attapulgite material in the form of carbonates and other inclusions. Despite this, they are a beneficial ingredient of cementitious tile adhesives in competition with polyacrylates and starch ethers. The advantage of MegaGel-30 is that their performance is not temperature sensitive and they have lower water demand. This grade is having free ions in an aqueous system to work. MegaGel-30 is a approved exfoliated Attapulgite where the clay has been chemically and mechanically purified into discrete particles about 2 Microns diameter. This material has special viscosity modification properties with high solid aqueous systems that cannot be matched with any other ingredients.
