Specifications

Product Description
A-Type Silica Gel

Our A-Type silica gel contains fine pores & has large internal surface area, including spherical and lumpy or irregular shape with transparent or semitransparent appearance. It has high moisture absorbing capacity at low humidity.


B-Type Silica Gel

B-Type silica gel is milky white, transparent or translucent, spherical or lumps shape. B-Type adsorbs water vapor at very high humidity and releases it at very low humidity.
