Description

Product Introduction:

Color-changing silica gel is primarily used to absorb moisture and prevent rust in instruments, meters, equipment, and other devices under sealed conditions. At the same time, its color change from blue to red upon moisture absorption provides a clear visual indication of the ambient relative humidity. When used in conjunction with conventional silica gel desiccants, it helps monitor the desiccant’s moisture‑absorption capacity and assess the relative humidity of the surrounding environment. As a packaging‑grade silica gel desiccant,

It is widely used in precision instruments, leather goods, footwear, apparel, food, pharmaceuticals, and household appliances, among others.
