The Basics of Silica Gel

Silica gel is a form of silicon dioxide, a naturally occurring mineral. It is most commonly found in a granular, porous form that is perfect for adsorbing moisture. Silica gel does not dissolve in water or react with most substances, which makes it ideal for various applications where moisture control is essential.

• Composition: Made from sodium silicate.
• Properties: Non-toxic, non-flammable, can adsorb moisture equivalent to 40% of its weight.

Common Uses of Silica Gel

Silica gel packs an impressive punch when it comes to protecting products from humidity and moisture.

Industrial Uses

Industries rely heavily on silica gel to maintain the integrity and longevity of their products.

• Electronics: Protects circuit boards, semiconductors, and other sensitive components from moisture.
• Pharmaceuticals: Ensures that medicines and vitamins stay dry to maintain their efficacy.
