【Industry Standard 2-4 mm】 High-quality silica gel uses physical adsorption. It has a strong moisture absorption capacity and both chemical and physical stability. It's cannot use for flower drying.
【Indicating Silica Gel Beads】 Indicating silica gel has an indicating function. The state of moisture absorption can be judged by the change of colors. At 25°C, Rh20%, the silica gel will start to change color after absorbing moisture and completely changes color after absorbing moisture under the condition of RH50%-60%.
【Rechargeable -- 2 Ways】: 1. Placing in Oven for 0.5 to 2 hours at 200 to 250F ; 2. Placeing in microwave for 10 Minutes at Defrost Mode; Can not over 250F and depending on the beads' condition, they may take shorter than the recommended time;
【Premium Silica Gel】 It is also non-corrosive, non-toxic, and harmless. The silica gel can be reused after being reactivated. It can replacement desiccant for air dryers and compressors;
