| Desiccant |
| A desiccant is a hydrating agent which attracts moisture from the atmosphere. It adsorbs and holds particles of water to itself by physical bonds or absorbs H2O to itself which is chemically integrated into another.This kind of desiccant is mainly used in shipping container. |

It is a naturally occurring mineral that is purified and processed into either granular or beaded form. As a desiccant, it has an average pore size of 2 angstroms and has a strong affinity for moisture molecules. Silica gel performs best at room temperature(20~32¡æ) and high humidity(60~90%). It will drop the relative humidity in a container down around 40% RH.

Its appearance is that of small gray pellets. Clay is a good basic desiccant that works satisfactorily below 50¡æ. Above 50¡æ, there is a possibility that the clay will give up moisture rather than pulling it in. The upside to clay is that it is normally the least expensive desiccant.

Molecular sieve is a synthetic desiccant that has a very strong affinity for moisture molecules. The pore size on the molecular sieve particles can be controlled by different manufacturing process. It can be used for picking up specific gases as well as moisture. Molecular sieve can hold moisture to temperatures well past 450¡ãF (230¡ãC). Because of its high affinity for moisture, molecular sieve is able to bring the relative humidity in packages down as low as 10% RH.
