When aggressive moisture adsorption is required in industrial or commercial applications, molecular sieves are often used. Molecular sieves can be obtained by a molecular desiccant supplier. These powerful desiccants can be used to remove any traces of moisture from a given environment; providing the right quantity is used.
Some of the common examples of the use of such a desiccant would be in electronic products as well as pharmaceutical products where any traces of moisture could harm the circuits.
What gives this desiccant a high adsorption quality is the presence of an intricate network of pores and empty cavities where moisture or vapors can be adsorbed. The pore sizes of this desiccant are measured in a unit called Angstroms.
Molecular sieves are available in versions such as 3X, 4X, 5X, 10X, etc. The higher the numerical value, the better are the adsorption capabilities. The chemical name of this desiccant is Synthetic Sodium Potassium or Calcium Aluminosilicate.
There are several desirable attributes of this particular desiccant that make it an ideal choice for use in demanding applications. Here are a few traits of this desiccant:
Considering these points, it is clear that molecular sieves are one of the easiest to handle desiccants.
However, given their aggressive adsorption properties, they are also among the more expensive molecular desiccants to purchase. This desiccant is normally sold in the form of beige beads or opaque tan. When packed in the adequate materials, these molecular desiccant packets can be kept along with different products.
Several firms are engaged in continued research relating to newer applications of this desiccant. Since molecular sieves have the ability to absorb up to 20% of their own weight, they can be used for extended moisture control applications. Some studies have shown that these desiccants can be effectively used in various applications to bring down the relative humidity to as low as 10%.
