All silica gels show the same behavior in water absorption. Only the differences at high loads can be justified by the varying maximum loadings. However, this maximum loading is well above the time of color change and is secondary to use in aeration dryers.
The loadings of the color envelopes vary greatly. The silica gel KC dry beads OC achieves the color change at the lowest loadings. As a result, the service life, the breakthrough curve and the water absorption take the lowest values. In contrast to this is the silica gel orange-colorless. This silica gel reaches the color changes only at high loads. This results in a long service life, a high breakthrough curve and a large amount of registered water. The orange-green and blue-pink silica gels have comparable properties in color change.
