SORBSTAR blue indicating silica gel packets are highly effective desiccants and deliver superior moisture absorption performance. It is designed to protect your products from moisture damage during storage and shipping.
It is made from 100% premium-grade virgin silica gel formulated with a cobalt chloride indicator and packaged in resealable moisture barrier bag.
Unlike standard white silica gel, these packets contain a moisture indicator—cobalt chloride—which changes color from blue (dry) to pink (saturated), clearly showing when the desiccant needs replacement.
Color Indicator Function – Beads turn from blue to pink as they absorb moisture:
Blue: dry, RH ≤ 20%
Gradual color change begins from RH ≥ 20%
Fully pink at RH 50%–60% (saturated)
