Product Desciption

Brief Introduction to top quality micro bead silica egel



Type-A Silica gel is also called TS6 silica gel and finepored silicagel. It looks transparent or translucent
vitreous silica gel, in the shape of sphere and lumpiness.

What is strongly recommended is of spherical form, with particle-size as 2.0-5.0 mm, which is widely
used nowadays by our customers.

Main function:
Type A silica gel mainly indicates its special characteristics with loads of micro-pores in its inner structure,
which is why relevant humidity and odors whatever may be easily adsorbed.

Main use:
Type-A silica gel is frequently used for drying and moisture-resistance, also as catalyst carriers, adsorbents, separators and variable-pressure adsorbents, tiny package desiccant bag,etc.

Silica Gel comprises Type A (finepored type), Type B (widepored type)  Type C (widepored type)
regular and irregular granular.

For Type A regular (spherical form) granular, its particle size mm covers the following:

2.0-5.0 1.-3.0 3.06.0 0.2-1.0 0.5-1.0 mm

For Type A irregular (lumpy form) granular, its particle size mm covers the following:

0.2-1.0  1.4-4.0  1.0-3.15  1.5-3.15  3.0-6.0 etc
