Color-changing silica gel breather valve desiccant 3-5mm blue color-changing silica gel Blue silica gel has the adsorption and moisture-proof function of fine-pore silica gel. Its characteristic is that during the moisture absorption process, it turns purple as the moisture absorption increases, and then turns light red. It can indicate the humidity of the environment and visually show whether the silica gel needs to be replaced or regenerated.

Applications

1. Mainly used for moisture absorption and rust prevention of instruments, meters, equipment, etc., under sealed conditions, while also intuitively indicating the relative humidity of the environment through its color change from blue to red after moisture absorption.

2. Used in conjunction with ordinary silica gel desiccants to indicate the moisture absorption level of the desiccant and determine the relative humidity of the environment.

3. As a packaging silica gel desiccant, used for precision instruments, leather, shoes, clothing, food, household appliances, etc.

Characteristics

The main component of color-changing silica gel is silicon dioxide, which has a strong adsorption effect on water vapor in the air. At the same time, it displays different colors based on the amount of moisture it contains, changing from blue before moisture absorption to light red as moisture absorption increases.
