Silica gel desiccant is a high-activity absorbing material in the form of granules or spheres of various sizes.
Its chemical name is Silicon Dioxide (SiO2). It is odorless, tasteless, and non-toxic. Silica Desiccant offers an excellent capacity for physical dehumidification because of its good absorbability, chemical stability, wide surface area and high mechanical strength.

1)Moisture absorption rate over 30%;
2)No physical forms changed after moisture absorbing, nontoxic, no harm, no pollution;
3)Good heat stability, strong mechanical strength;
4)Widely used in shoes, hats, leathers, handbags, food, medicine, metals, toys, bamboo and wood, instruments, electronics, etc.
