Polymer grade (PG) montmorillonites are high purity aluminosilicate minerals sometimes referred to as phyllosilicates. They are intended for use as additives to hydrophilic polymers such as polyvinylalcohols, polysaccharides and polyacrylic acids. When fully dispersed in these host polymers they create a new category of composite materials called nanocomposites.
Loading Levels
PG montmorillonites are used at loading levels ranging from 5-25% depending upon the degree of hydrogen bonding with the host polymer and the requirements of the application.
Morphology and Structure
Montmorillonites have a sheet-type or platey structure. Although their dimensions in the length and width directions can be measured in hundreds of nanometers, the mineral’s thickness is only one nanometer. As a result individual sheets have aspect ratios (L/w) varying from 200-1000, with a majority of platelets in the 200-400 range after purification. The theoretical formula and structure for montmorillonite are:
This exact formula is never seen in nature because central metal ions (A13+ and Si 4+) in the interior crystal lattice have been substituted for lower valance ions such as magnesium, iron, manganese and occasionally lithium. Substitution creates a charge imbalance on the flat surfaces of each platelet. The negative charge imbalance is neutralized by adsorption of hydratable cations, most notably sodium and calcium.
Adsorbed cations can be intentionally substituted by other hydratable cations including organic cations. The degree of potential substitution is expressed as cation exchange capacity, measured in milliequivalents of substitution per 100 grams of mineral. 
Purity and Color
All PG grades are purified to a level greater than 98% montmorillonite. Admixture minerals are generally those with specific gravities similar to montmorillonite and include albite, calcite, dolomite, orthoclase and quartz. Color varies between grades.
Color is the result of substitution by iron, titanium and manganese within the lattice structure and depends on the level of substitution and valence states of the cations. Because these metals occupy the central coordination positions within the structure, they cannot be economically removed.
Availability
PG montmorillonites are available in 20 kgs (44 lbs) bags or drums and one metric ton bulk bags.
Montmorillonite products are divided into inorganic montmorillonite and organic montmorillonite. Among them, inorganic montmorillonite includes sodium based montmorillonite and lithium based montmorillonite, with high purity and good consistency, which can meet various modification needs; Organic montmorillonite is modified with organic treatment agents that have good temperature resistance and high purity for different applications, which can fully utilize the role of montmorillonite
