Discover our Type B Silica Gel Separators in bags of 20kg or 500kg. Cobalt-free blue silica gel for effective moisture absorption.
Blue silica gel is a type of desiccant that changes color from blue to purple to light pink as it absorbs moisture. It can indicate the humidity level of the environment and the need for replacement. It can be used alone or with Type A Silica Gel.
Blue silica gel is mainly used for absorbing moisture and preventing rust in instruments, gauges, and equipment in enclosed conditions. It changes color from blue to red to visually indicate the relative humidity of the environment. It is commonly used in packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household appliances.
