Silica Gel White Desiccant
Economical high-capacity packaging desiccant
White silica gel beads and granules with up to 40% moisture adsorption for packaging protection.
Product Overview
White silica gel is a porous, chemically inert silicon dioxide that physically adsorbs moisture without changing form or reacting with the protected goods. It adsorbs up to 40% of its own weight in water vapor, protecting electronics, leather, pharmaceuticals and food from humidity damage during storage and shipping.
Our white silica gel is offered as beads (2-4mm) and granules (1-3mm), with FDA-compliant grades for food contact and cobalt-free formulations suitable for environmentally sensitive markets.
