Specifications

1. direct silica gel manufacturer
2.Turning from original color to another after absorbing moistures.

Characteristics
Shape: glass-like pellets or lumps.
Color: blue or light blue.
Including blue gel indicator, chromotropic silica gel and blue silica gel.
Turning from blue to red after absorbing moistures.
