What is Silicon Dioxide?
Silicon Dioxide (SiO2), commonly known as Silica, is one of the most abundant compounds on earth and an essential industrial raw material in its synthetic amorphous form. Polychem Industries supplies synthetic amorphous Silicon Dioxide produced via precipitation or fumed processes — distinct from crystalline silica (sand/quartz) — in the form of an extremely fine, lightweight white powder with a very high surface area.
We supply Precipitated Silica and Fumed Silica grades to rubber manufacturers, paint and coating companies, food processors, cosmetic formulators, and pharmaceutical companies across India and internationally. Its unique combination of high surface area, reinforcing ability, and thickening properties make it indispensable across diverse industrial sectors.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Industrial / Food Grade | White amorphous powder | 98–99.8% depending on grade | Industrial / FSSAI | Rubber, paints, food anti-caking, cosmetics, pharma |
Applications & Uses
Rubber & Tyre Industry
The largest application globally. Precipitated Silica is used as a reinforcing filler in tyre treads (especially "green tyres"), rubber compounds, and footwear, improving wear resistance, rolling resistance, and wet grip performance.
Paints, Coatings & Inks
Used as a matting agent, anti-settling agent, and rheology modifier in paints and coatings. Controls gloss level, prevents pigment settling, and improves scratch resistance in industrial and architectural coatings.
Food Anti-Caking Agent
Food Grade Silicon Dioxide (E551) is used as an anti-caking and free-flow agent in powdered foods including spices, soup mixes, salt, and powdered beverages, preventing clumping caused by moisture absorption.
Cosmetics & Personal Care
Used as a thickener, anti-caking agent, and mattifying agent in cosmetics including face powders, toothpaste, and skincare formulations. Provides oil absorption and a smooth, silky after-feel.
Pharmaceutical Excipient
Used as a glidant and flow aid in tablet and capsule manufacturing, improving the flow properties of powder blends during high-speed tableting and ensuring uniform fill weights.
Adhesives & Sealants
Used as a thixotropic thickening agent and reinforcing filler in silicone sealants, adhesives, and specialty rubber compounds, providing anti-sag properties and improved mechanical strength.
