Silica (SiO₂), also known as silicon dioxide, is a naturally occurring compound found in sand, quartz, and other minerals. In industrial applications, precipitated silica and fumed silica are the most widely used synthetic forms.
White, fine powder – unlike Carbon Black, silica is white and non-staining
Reinforcing filler – improves mechanical properties of rubber compounds
Low rolling resistance – enhances fuel efficiency in tires
High surface area – improves strength and tear resistance in elastomers
Chemical inertness – resistant to many chemicals and high temperatures
Rubber & Tire industry – as a reinforcing filler, especially in “green tires” to reduce fuel consumption and increase wet traction
Plastics & Coatings – as a thickener, anti-blocking, or matting agent
Adhesives & Sealants – improves rheology and durability
Food & Pharma – used as an anti-caking agent in powders
Electronics & Specialty – used in polishing slurries, insulation, and high-tech materials
