The main component of silica gel is silica. It has the developed porous structure, non-toxic, odorless, stable chemical properties, strong moisture absorption and other advantages. Due to its wide pore size range, it can also adsorb Substances such as alcohol, ammonia, aromatics and olefins. At the same time, silica gel is also the only desiccant that has passed the US FDA certification and can be used in direct contact with drugs and food.
