Product Description

Silica gel white/orange/blue supplier in China-Qingdao Tongzhou New material Co., Ltd

Product Description

Silica gel is a highly active adsorption material, which is usually made from the reaction of sodium silicate with sulfuric acid after a series of post-treatment processes. Silica gel belongs to amorphous substance. Its main component is silicon dioxide, content is more than 98%, insoluble in water and any solvent, non-toxic, odorless, stable chemical properties.
