Desiccants (Silicagel / Weissgel) by TROPACK Packmittel GmbH

Desiccants as loose/bulk goods

Our highly activated desiccants come in various forms, including bulk. Be it silica gel, molecular sieves, Rubingel, orange gel, Envirogel or clay, all desiccants are also available as bulk goods in various packaging sizes – from small 1-kg tins, to barrels and drums, to big bags.

TROPACK desiccants use physical forces to integrate moisture into their structures, which consist of layers, pores and channels. Desiccants are not water-soluble. Desiccants with special properties and different shapes and grain sizes can be tailored to your specific purpose.

Silica gel / White gel

Silica gel is an amorphous and porous form of silicon dioxide that is widely used as a desiccant to adsorb moisture. This silicon dioxide has a very high SiO2 content, and is produced through a controlled chemical reaction between sodium silicate and sulphuric acid.

Silica gel does not form any vapour, is completely odourless, and does not corrode metals.

Our silica gel is FREE from dimethyl fumarate.

Microporous silica gel

Microporous white silica gel is used as “standard silica gel” to sharp-dry air. The large inner surface with the tiniest pores can adsorb up to approx. 36% of its own weight in moisture.

At 23°C and 40% RH (test conditions as per DIN 55473), silica gel adsorbs approx. 25% of its own weight.

Its high adsorption capacity means silica gel is commonly used in  places with limited space where maximum moisture needs to be adsorbed with minimal desiccant, and thus particularly in pharmaceutics, diagnostics and industry.

Forms and graining:

  • Form: Granulate, beads or crushed beads
  • Graining: 0.2 – 5 mm

Macroporous silica gel

Macroporous white gel is ideal for absorbing water in liquid form.

It is commonly used in places where water can appear in an air or gas flow. It serves as a buffer gel here, and is often placed as an initial barrier in front of microporous silica gel.

Silica gels can be fully regenerated when heated to approx. 150°C.

Silica gel with indicator

White silica gel is also available with colour indicators. These indicator gels enable highly accurate visual checks of the desiccant’s saturation level. The change in the indicator’s colour tells users when the silica gel needs to be replaced.
