Blue Silica Gel

Blue silica gel desiccant beads are divided into two types: cobalt chloride-containing and silica chloride-free. The index and color rendering are the same, except that the composition content is different, making both suitable for indicating silica gel bulk applications where visual humidity monitoring is required. Because some countries have strict restrictions on the use of cobalt chloride components. Siliplus, as one of the leading blue silica gel manufacturers, launched two products with different content. They can all change from blue to pink. When the color of silica gel blue beads is pink, it means that the desiccant needs to be replaced again. When sourcing indicating desiccants for export markets with compliance requirements, buyers often compare qualified silica gel blue manufacturers to ensure stable color change performance and consistent product standards.
