Silica gel beads like those used in VaporBeads™ are a highly effective, non-toxic desiccant that are used to control humidity levels in a wide range of applications. These beads can be used to maintain desired humidity levels in food packaging, electronics, museums and other industries where moisture needs to be kept at an optimal level. Silica gel beads can absorb up to 40% of their weight in moisture and give off minimal amounts of dust when handled correctly. The high absorbent properties of these beads make them an ideal solution for humidity control in many applications - including humidors!
The graph above illustrates the moisture capacity with relative humidity. As you can see, silica gel is superior with regards to its sorptivity.
