Desiccants come in various forms, they can be made utilizing agents, such as montmorillonite clay or silica gel, molecular sieve, and more.

Typically used in transport, storage or maintenance of materials and products, desiccants are used to keep everything from gym shoes to military munition dry.

Desiccants are Aimed to Combat:

  1. 1. Internal packaging water vapor in the air
