The main component of silica gel desiccant is SiO2, the appearance is transparent or translucent solid sphere, the microporous structure of SiO2 has formed capillary absorption and condensation to strong moisture absorption, moisture absorption after not deliquescence. Comply with HG/T2765 (Chinese chemical industry standard) and JIS-Z-0701 (Japanese industrial specification standard).

1. Physical adsorption, the reaction is mild, safe and reliable.

2. Innocuous and harmless, no odor, no harm to human health;

3. The chemical properties are stable and have strong mechanical strength.

4. The particles are uniform and surface dry, and there is no obvious change in appearance before and after use.

5. Reusable, after moisture absorption, dry and renewable;
