What are the three major types of desiccants?
1) Montmorillonite Clay- A calcium aluminum silicate type of hydrous clay which is ground, processed and bagged. It is a naturally occurring non-hazardous substance. Clay,the least expensive of all desiccants, is used in most industrial applications requiring humidity control. 2) Silica Gel- A form of silica manufactured from sodium silicate and sulfuric acid. Like Clay, Silica Gel is non-hazardous and is capable of adsorbing 40% of its weight in water vapor at 100% humidity. Silica Gel has a porous molecular structure that closely resembles a sponge, and has the highest capacity of any commercial desiccant for moisture adsorption. 3) Molecular Sieve- A manufactured crystalline version of Zeolite containing a network of uniform pores and empty cavities. Molecular sieve is derived from sodium, potassium or calcium alumina silicate. It is a non-hazardous material. Molecular sieve is the desiccant of choice for the most demanding and unique applications. Molecular sieve is the most aggres
