Molecular Sieve 4A to keep your Products Moisture Free

We all know the importance of keeping moisture out of certain foods and pharmaceuticals. One of the most effective methods of doing so is with the use of molecular sieves. There are also several liquids and gases that interfere with their composition when they come in contact with them.

The Importance of Molecular Sieve Desiccants

Molecular sieve desiccants have a much more powerful action when it comes to keeping unwanted liquids and gases when they are packed. The other well-known desiccants are comprised of either alumina or silica gel, but they are no match when compared to the potential that molecular sieves 4A have. They have one of the most effective dryings and absorbing properties known in the industry.

Molecular sieves are especially famous for their water purifying properties. Being very small in size, they have huge absorbing qualities. When water passes through them, its molecules get caught in the tiny pores and allow only clean and pure water to pass through, absorbing all the impurities. This is also the case with many other liquids and gases where high purity is essential.

Molecular sieves come in various sizes and specifications; each one of them is used for a particular purpose. They can be classified as 3A, 4A, 5A and 13x categories. Each one of them has a special role to play and can be used to perform various drying, purifying or absorbing applications.
The Special Features of Molecular Sieves

One of the most important features of molecular sieves is that they have the special ability to absorb about 22% of their original weight of gases and liquids. Using the adsorption process, molecular sieves are one of the cheapest and most convenient forms of keeping moisture and toxic gases out of many chemical processes, or during the final packaging stages.
The desiccant packets made from molecular sieves offer maximum protection from moisture and are very versatile in their applications. They also offer the best value for money for this purpose. One of the important factors is that they offer an atmosphere for products that require a very low RH level (Relative Humidity). They are especially suited where very high temperatures are involved. They are also very easy to use, as they are packed very conveniently in nontoxic or reactive packing materials like polyester or polyethylene bags. Tyvek or cotton bags are also used to suit the end process.
