Silica Gel for Moisture Control & Filtration 

Type E silica gel is a fine-pore desiccant that adsorbs and retains moisture. It is well suited to maintaining low-humidity conditions (0–30% relative humidity), where fine-pore gel retains moisture more effectively than wide-pore grades, and contains no color indicators. Gremarco impregnates Type E silica gel into filter media, so the desiccant is bonded to the substrate rather than supplied loose.

Silica gel desiccant media is a filtration material that adsorbs water vapor to control humidity in air and gas streams, protecting sensitive products, components, and enclosed environments from moisture damage.

Silica gel media is commonly used in electronics enclosures, pharmaceutical and food packaging, laboratory instrumentation, compressed air drying, and HVAC and industrial moisture control systems.

Yes. Silica gel media can be supplied in different substrates, thicknesses, sizes, and converted formats depending on application requirements.

Yes. In many applications silica gel can be regenerated by heating to 290–440°F to drive off adsorbed moisture, restoring adsorption capacity and allowing reuse.

Gremarco impregnates high-purity Type E silica gel — minimum 99.6% silica content, chemically inert, non-toxic, non-corrosive, and odorless — into filter media substrates. This fine-pore desiccant is well suited to maintaining low-humidity conditions and can be regenerated at 290–440°F for reuse in many applications. Combined with multiple substrate options, custom formats, and in-house converting, this lets us match the media precisely to your application.
