Silica Gel

Running offers a variety of silicon gels, including white silica gel, blue silica gel and yellow silica gel products for a large number of dehydration applications, such as fluid cracking catalyst, catalyst carrier, packaging desiccant, compressed air dryer and others. The silica gel’s color will change after absorbing water: blue silica gel and yellow silica gel turn pink and dark green respectively, when saturated.

Our silica gels are available in two types: bead or granular, depending on customer needs. If you are a desiccant retailer, we also offer customized packaging services.

1. Silica gel does not react with chemicals, and it is tasteless, odorless, non-toxic, and non-corrosive.
2. Silica gel is highly porous and is capable of absorbing large amounts of water due to its large internal surface area.
3. Silica gel acts as a desiccant even when fully saturated with water.

    1. 3A Normal Molecular Sieve3A normal molecular sieve can be used to dry petroleum pyrolysis gas and unsaturated hydrocarbon materials, such as ethylene, propylene, butadiene, acetylene and more, or benzene, toluene, xylene and other solvents, such as methanol and ethanol. Also, it helps dry carbon dioxide gas in food grade, coal oil and jet fuel.
    1. 3A-XH Molecular Sieve Desiccant for Refrigerants3A-XH molecular sieve desiccant for refrigerants is silica aluminates in potassium and sodium form with a pore opening of 3 angstroms or 0.3 nm. It is a generic kind of desiccant, which can be classified as three types of molsieve adsorbent, XH-7 type, XH-9 type and XH-11 type.
