Product Description

Product Description

1.Silica Gel Desiccant is a kind of odorless, tasteless, non-toxic, high activity absorption material with strong adsorption capacity.
2.It has a stable chemical property and never reacts with any substances except the Alkai and Hydrofluoric-acid, safe to be used with foods and pharmaceuticals.
3.Silica Gel Desiccant whisks away moisture to create aprotercyive environment of dryair for safe storage.

Application

1. Mainly used for moisture absorption and rust prevention of instruments, meters and equipment under closed conditions.  

2. Used with ordinary silica gel desiccant, indicating the degree of moisture absorption of desiccant and judging the relative humidity of the environment.  As a desiccant for packaging, silica gel is widely used in precision instruments, leather, clothing, food, medicine and household appliances.  

3. Because of its food-grade use, silica gel can be used to make baby pacifiers and other products in direct contact with the human body. In addition, silica gel can also be used to produce condoms and breast implants.  

4. Common materials for making blood pumps.
