white silica gel

Type A silica gel, also known as fine-pore silica gel or narrow pore silica gel. It is milky white, translucent, spherical material. It is odorless, non-toxic, and poses no harm to the environment. Type A silica gel features small pores and a large specific surface area, making it suitable for high adsorption at low humidity. It demonstrates excellent adsorption performance in environments with relative humidity ranging from 20% to 50%, especially characterized by fast adsorption speed at low relative humidity.
