In this type all the particles of Silica Gel are impregnated with an indicator. When free from moisture the particles are blue silica gel or orange silica gel. As they are put to use, the particles take up moisture, Silica Gel gradually turns pink or green and gives a ready indication that it has done. Its work and requires replacement or regeneration. The above product is free from foreign impurities such as Chlorides, Sulphates and other organic matter and has high absorption efficiency.
