The Chinese Government environment protection agency has shut down many silica gel manufactures. There is now a severe silica shortage effecting prices and supply.
There are several excellent replacements for silicagel. For example Activated Clay, such as our Ecobag desiccant, which has a higher absorption rate and a lower price.
The more high end solution is a Calcium Chloride based desiccant, such as our IPD, with the highest absorption rate.
