The white silica gel in amorphous crystals (granules) has a standard granulometry variable between 3 and 6 mm. It is the classic white silicagel without any color indicator, so it is a product that is not able to change color to signal the transition from dry and new to wet and exhausted.
The white silica gel in granules looks the same as normal coarse cooking salt. It is a product that in industrial applications is particularly suitable for use in gas, air and filter treatment plants in general, while bearing in mind that not being able to turn in color the level of exhaustion of the product can only be verified by weighing.
The white spherical silica gel has the same characteristics of the classic silica gel in granules, the standard granulometry is 2.5-5 mm. The difference lies in the shape of the crystal that is in spheres (or beads). The spherical white silica gel is particularly suitable for drying flowers and plants, since the beads, being perfectly smooth and rounded, can not cause damage to the plant.
The spherical white silicagel is devoid of any color indicator, so it is a product that is not able to change color to signal the transition from dry and new to wet and exhausted.
The brown silica gel is a particularly valuable product as it is equipped with a chromatic indicator that allows the product to signal the change of state from dry and new (amber yellow) to wet and exhausted (light blue). It has a standard granulometry variable between 3 and 6 mm. The color indicators are made of harmless substances (cobalt free) and the product is DMF free. The silicagel brown is in granules and is particularly suitable for all industrial applications where the product must be inserted in filters or air or gas circulation systems in general, as the relatively wide interstices present between the material allow better circulation of air.
Silica gel orange is a dehydrating product with a chromatic indicator and characterized by spherical crystals (beads). Compared to brown silica gel, orange is characterized by a lower density because spherical crystals occupy a reduced amount of volume at the same weight. The Orange silicagel, thanks to the presence of the chromatic indicator, is widely used in many sectors of application, especially at the industrial level and museum conservation. The product has an inert color indicator, harmless and totally cobalt free and DMF free. The standard granulometry is 2.5-5 mm.
