· Meets FDA specifications for contact with food and drugs.
· Provides superior adsorption. Remains dry at maximum saturation.
· Silica gel can adsorb 15% of its weight in water vapor in 2 hours.
Silica-gel absorbent is a high-activity absorbent, which is the result through chemical reaction between sodium silicate and sulfuric acid and then ageing and sour bathing. Silica-gel is an amorphous substance. It features a stable chemical property and never reacts with any substance except the alkali and hydrofluoric acid. Because of chemical composition and physical structure of silica-gel, it possesses many advantages as desiccant. For example, high absorption capacity and non-shape changing. It is a non-toxic, odorless and green-environmental material.
