With an extreme uniform and intricate network of pores, molecular sieve offers ultimate moisture absorption solutions. This makes this especially preferable in the industrial sector where there is a constant need to adsorb gases and liquids. These adsorbents are a synthetically manufactured form of Zeolite, and feature innumerable empty cavities, which is what endows it with the highest adsorption capacity in comparison with other desiccants.

However, it is this very quality that also makes it one of the most expensive adsorbents available today. This desiccant is derived from substances such as calcium alumina silicate or sodium potassium. Most China molecular sieve manufacturers offer standard prepackaged molecular sieves for industrial use. However, if you require personalized solutions, these can be availed too. For this you would need to enlist the services of a reputable desiccant manufacturing firm.

Just like silica gel, this particular desiccant also comes in the form of granular beads, but they bear a pinkish tinge.

Characteristics and Uses of Molecular Sieve

Here are some other notable features of these desiccants or sieves:

  • They can either be used individually or custom blended with some other desiccants to give you an optimal adsorption solution.
  • Different desiccants have different adsorption capacities. In the case of a molecular sieve, you can expect it to adsorb moisture or gas up to 20 times its own weight.
  • Since it is one of the most aggressive desiccants available in the market today, it costs significantly more than its other counterparts.
  • Where tight humidity control is needed, there couldn’t be better option than this particular desiccant. That’s precisely why it’s used in places such as museums to protect invaluable artwork from the adverse effects of moisture and humidity. The right use of this desiccant can allow you to bring down the relative humidity to as low as 10%.
  • A number of pharmaceutical companies make use of molecular sieves to protect packaged drugs and antibiotics from humidity, especially during the transportation and warehousing stages of the distribution cycle.
  • The efficacy and suitability of this desiccant is determined by its pore size. These pore sizes are measured in Angstroms. The common pore sizes are 3A, 4A, 5A, 8A and 10A.

Wrap Up

So, right from protecting expensive artwork to pre-purification of water to absorbing carbon dioxide, there are several industrial applications in which this desiccant is widely used. Since this desiccant is odorless, it can also be used with pharmaceutical products. In addition, with a melting point that is slightly less than 2900 degrees Fahrenheit molecular sieves are very suitable for use in high temperature applications. They are also used in chemical reactions since they are stable. However, as safe as this desiccant is, one should always wear a dust mask and gloves while handling it.
