Silica Gel Tyvek Packets can absorb large amounts of water and other substances such as HC1, CO2, C12, or aromatics. Silica Gel is odorless, tasteless, and chemically inert. This makes it a non-corrosive and non-toxic method of moisture control, especially since it will not react to other chemicals and keeps its size and shape. In this way, Silica Gel packets can limit the growth of mold and prevent spoilage or other damage. Silica gel packets have extensive use as a moisture absorber in everything from electronics to medicine. In particular, these desiccant packets are used in compressed air systems. By flowing compressed air through a gel packet, it is possible to prevent moisture buildup and subsequent breakdowns. This applies in industrial settings and railway locomotives. Similarly, high frequency radio and satellite transmission systems rely on a moisture absorber in conjunction with a compressed air system to prevent signal degradation. The desiccant packets gel is also useful in museum and libraries, where it serves as a preservation tool. By keeping moisture out of the air, these desiccant packets protect the integrity of the items being stored, many of which are susceptible to damage due to age. Other uses include cat litter and long term storage.
