RS PRO Silica gel supplied in small packs that change colour from yellow to green to indicate the presence of moisture. These sachets have been designed specifically for the electronics industry and provide both moisture and electrostatic protection. The material is designed to absorb moisture from air, gases and liquids to prevent the relative humidity (RH) rising to a point when corrosion, fungal growth and optical smearing will occur.

Humidity indicating desiccators are hygroscopic (tendency to absorb moisture from the air) substances that protect against dampness, corrosion and contamination. The material is inert to most chemicals and therefore will not induce corrosion.

Can be used in packaging and transportation of electrical, electronic and mechanical components, communication equipment, adjacent to metallic structures, cable joints and hygroscopic powders.

RS PRO silica gel desiccant is an essential component for any device or equipment susceptible to moisture attack and ideal for a range of packaging requirements.
