Silica gel absorbent is a kind of hydrophilic polar absorbent mainly made from silica gel. Silica gel is a kind of rigid granulated silicic acid polymer that may has amorphous chain structure and reticular structure.
The nontoxic and tasteless substance has stable chemical property and will not react with any matter except caustic alkali and hydrifluoric acid.
According to the size of pore volume, silica gel can be divided into macroporous silica gel, B type silica gel, and fine pored silica gel, etc.
Due to its special chemical components and physical structure, silica gel absorbent has its particular characteristics, such as high absorption property, good heat stability, stable chemical prpperty, high mechanical strength, etc.
Silica gel absorbent is mainly used to separate the gas mixture from petroleum constituents.

About our Silica Gel Absorbent
As a professional silica gel absorbent manufacturer in China, we mainly provide B960, B980 and B990 aerosol silicon dioxide absorbent for enamel paper.
They have large volume and thus can achieve good oil-absorbing effect. Their pore volume can be 3.5~3.8ml/g.
The aerosol silicon dioxide absorbent has narrow particle size distribution, which can make the coating more smooth and clean. The particle size can be controlled within a certain range, through advanced process control and thorough inspection methods.
Our aerosol silicon dioxide absorbent for enamel paper has good water solubility. This can make the coating more evenly and oil absorption more thoroughly. Processed via special surface processing technology, our enamel paper aerosol silicon dioxide absorbent can disperse in water evenly, without agglomeration.
