Loading... Please wait...Loose Silica Gel (Bulk): Silica Gel can adsorb up to 40% of its weight in moisture and has the highest absorption capacity of any commercially used desiccant. Our loose silica gel beads are Self Indicating and mixed with Non Indicating Silica Gel at a ratio of 95% white 5% blue. The blue beads change to pink indicating the silica gel has become exhausted and should be replaced or regenerated.
