Introduction
A type silica gel or silica gel A, is an amorphous, highly active adsorbent material with the narrowest pore size distribution. Silica gel A is a fine-pore silica gel, and its average pore size is 2~3 nm. Type A silica gel is considered the basic material for conventional white or transparent silica gel, as well as indicator silica gels.
Type A silica gel has a small pore size but a relatively large specific surface area, giving it a strong ability to adsorb water molecules, especially in low humidity conditions where it exhibits high hygroscopic efficiency.
Type A silica gel is the mainstay product among desiccant silica gels. It boasts strong moisture absorption and rapid drying speed, it is the standard material for drying industrial air and compressed air, so it is one of the most commonly used types of silica gel. In addition, type A silica gel is also applied in the moisture prevention and sealing of food, medicine and precision instruments, and as a substrate for color-indicating silica gel, etc.
