Colorful Silica gel and Color-changing Silica gel.

（Silica gel with Alumina, Fragrant silica gel, Orange silica gel.）

（1）Silica gel with Alumina.

Silica gel with Alumina is light yellow, its chemical molecular formula is: SIO₂.nAl₂O₃.mH₂O. It is chemically stable and insoluble in any solvent.

In comparison with Fine-pored silica gel, the adsorption capacity of fine-pored Silica gel with Alumina is quite the same when used at low relative humidity(RH=10%,RH=20%),while its adsorption capacity at high humidity (RH=80%,RH=90%) is about 25% higher than that of Fine-pored silica gel. Its thermal stability is over 150℃ higher than that of Fine-pored silica gel(200℃)Silica gel with Alumina is mainly used for the dewatering of natural gas, adsorption and separation of light hydrocarbon at variable temperatures. It may also be used as catalyst and catalyst carrier in petrochemical industry, industrial drier, liquid adsorbent, gas separator and Cat sand.

（2）Fragrant Silica gel.

Fragrant Silica gel is made by further processing the common silica gel. It not only has high adsorption capacity, but also has colorful appearance and joyful fragrant smell.

According to the different kind of essence, Fragrant Silica gel are categorized into fruit series, flower series and wonderful series.

Fragrant Silica gel is used in car, hotel, wardrobe, kitchen and toilet to absorb the peculiar smell/ moisture and release various pleasent fragrance. It can also be used in high grade fashionable dress, leather and jewelry.

（3）Orange Silica gel.

It is developed on the basis of Blue Silica gel Indicator. It adopts a new type of composite dyeing agent that is nontoxic. In this way, it prevents the environment pollution caused by dyeing agent from the very beginning. With its unique technique and adsorption performance, it has become a new type of environmental friendly product.

Varieties:
