Silica gel desiccant is made of high-quality silica gel raw materials, and after multiple steps of screening to ensure that each silica gel particle is clean and dust-free, and the particles are uniform. The moisture absorption is stable and the moisture absorption speed is fast. The adsorption rate is as high as 35%, the state does not change before and after use, physical adsorption, mild reaction, non-toxic and harmless. The silica gel desiccant can be reused by drying at high temperature after absorbing moisture.
