Angular, glassy crystals in white non-indicating and blue indicating, graded across six mesh ranges from 9–12 mm down to under 1 mm.
Bulk Silica Gel
Cobalt-free and DMF-free in both white and blue
The crystal form is the most economical way to buy silica gel in volume. Irregular angular granules pack densely and are ideal where the gel is being loaded into bags, breathers or bulk enclosures rather than dispensed into small sachets. Both the white non-indicating and blue indicating grades are supplied cobalt-free and DMF-free.
