Orange Silica Gel Deccicant

Products introduction:

Characteristics: Orange silica gel classified by shape:orange silica gel beads and granules. Its main content is silicon dioxide and it can change color to show the relative humidity in the air. Compared with blue silica gel, orange silica gel doesn’t contain cobalt chloride , so it’s non-toxic and harmless.

Product Details

Application:

The product can be used alone or be mixed with other silica gel to dry and indicate the humidity. It’s widely used in precision instruments, Pharmaceutical industry, petroleum industry, chemical, Food, Clothing, Leather industries, household appliances industry etc. Orange silica gel has a strong capacity of absorption of moisture. During the process of absorption moisture, the appearance of the color changes obviously according to the hygroscopic capacity.So it’s often called “ humidity indicator.”
