Silicon Dioxide 10kg

Whatsapp Order

Silicon Dioxide (SiO₂), commonly known as silica, is a naturally occurring inorganic compound found abundantly in the Earth’s crust. In its refined, powdered form, it is used as an anti-caking agent, filler, absorbent, and thickener across a wide range of industries. It is odorless, tasteless, chemically inert, and stable under normal conditions. Packaged in 10kg units, silicon dioxide is highly versatile and widely accepted for use in food, pharmaceutical, cosmetic, and industrial applications.
