Transformer desiccant 0.5kg/bottle, blue to pink, 3-5mm

Color-changing silica gel possesses the adsorption and moisture-proof properties of fine-pore silica gel. Its distinctive feature is that during the moisture absorption process, it gradually turns light blue as moisture absorption increases, eventually becoming light red or light pink. It can indicate environmental humidity and visually show whether the desiccant needs replacement.

Blue silica gel has the adsorption and moisture-proof effect of narrow pore silica gel, It is characterized by the moisture absorption process, it can become Light blue with the increase of moisture absorption, and finally become light red or light pink. It can indicate the humidity of the environment and also visually show whether a new desiccant needs to be replaced.

Color-changing silica gel is widely used for moisture-proof packaging in transformers, electrical cabinets, precision instruments, leather products, clothing, and household appliances. It can be used alone as a desiccant or in combination with fine-pore silica gel.
