Pyrogenic Silica Powder

High Surface Area Pyrogenic (Fumed) Silica for Specialty Applications

Product Summary

Pyrogenic Silica Powder — Pyrogenic Silica Powder, also known as fumed silica, is an ultra-fine amorphous silicon dioxide produced through a high-temperature flame hydrolysis process. It is characterized by extremely high surface area, low bulk density, and strong thixotropic and reinforcing properties. Pyrogenic silica is widely used as a rheology control agent, anti-caking additive, and reinforcing filler in high-performance industrial and specialty formulations.

Applications

  • Paints & CoatingsUsed as a rheology modifier to control viscosity, prevent sagging, and improve storage stability.
  • Adhesives & SealantsEnhances thixotropy, strength, and consistency in adhesive and sealant systems.
  • Silicone Rubber & ElastomersActs as a reinforcing filler to improve tensile strength, tear resistance, and mechanical performance.
  • Pharmaceutical & Personal CareUsed as a glidant and flow aid in tablets, powders, and cosmetic formulations.
  • Food & Nutraceutical (Selected Grades)Applied as an anti-caking agent and flow enhancer in powdered food products.
  • Chemical & Industrial FormulationsUsed as a carrier, thickener, and stabilizing agent in specialty chemical formulations.
  • Ink, Toner & Printing ApplicationsImproves dispersion, flow properties, and print quality in inks and toners.
  • Export Supply for Specialty ManufacturersSupplied in bulk quantities to global manufacturers across coatings, elastomers, pharma, and specialty chemical industries.
