Orange Silica Gel

Short Description:

The research and development of this product is based on blue gel color-changing silica gel, which is an orange color-changing silica gel obtained by impregnating fine-pored silica gel with inorganic salt mixture. environmental pollution. The product has become a new generation of environmentally friendly products with its original technological conditions and good adsorption performance.

This product is mainly used for desiccant and indicating the degree of saturation of desiccant and the relative humidity of sealed packaging, precision instruments and meters, and moisture-proof of general packaging and instruments.

In addition to the properties of blue glue, orange glue also has the advantages of no cobalt chloride, non-toxic and harmless. Used together, it is used to indicate the degree of moisture absorption of the desiccant, so as to determine the relative humidity of the environment. Widely used in precision instruments, medicine, petrochemical, food, clothing, leather, home appliances and other industrial gases.
