Molecular Sieves 3A

Back

Molsieve 3A manufactured by GMGBC is a crystalline Alumino Silicate with SiO2, Al2O3 in 2:1 ratio. It is formed by an extensive cross-linking of AlO4 and SiO4 tetrahedral, resulting in a uniform pore opening of 0.3 nm. GMGBC manufactures Molsieve 3A in the form of extruded pellets and spheres with state-of-the-art technology. The products have at least equal to and, in some cases, better properties than what have been specified in the Bureau of Indian Standards: BIS 14211:1994. Specifically, Molsieve 3A has very high water adsorption capacity and mechanical strength, and at the same time very low attrition loss. GMGBC uses clays from their own mines for manufacture of this product, ensuring better control and uniformity in the quality of final product.

Applications

Cracked Gas and Olefins drying, liquid or gas Propylene drying, drying of organic liquid like Methanol, Olefins, Ethanol, insulating glass manufacture, drying of CO2, Solvents, Reactant Mixtures, Gases and Liquid in the pharmaceuticals, paints, chemicals and allied industries.
