Fumed Silica
Fumed silica, also known as pyrogenic silica, is an extremely versatile material with a wide range of applications due to its unique properties, such as high surface area, low bulk density, and excellent thixotropic behaviour.
Fumed silica is favoured for its non-toxic nature, chemical inertness, and ability to enhance the performance of various products across industries.
Use of Fumed Silica
1 / Thickening and Thixotropy
-
Paints and Coatings: Acts as a thickener and anti-settling agent, improving the stability and flow properties.
-
Adhesives and Sealants: Enhances viscosity and prevents sagging or dripping during application.
-
Cosmetics and Personal Care: Used in creams, lotions, and gels to provide the desired texture and stability.
2 / Reinforcement
Rubber and Silicone Elastomers: Improves tensile strength, tear resistance, and abrasion resistance in products like tires, seals, and gaskets.
3 / Anti-Caking and Free-Flow Agents
-
Food Industry: Prevents caking and enhances the flow of powdered products like spices, milk powder, and salt.
-
Pharmaceuticals: Maintains the free-flowing nature of powders in tablets and capsules.
4 / Insulation
-
Aerogels and Thermal Insulation Materials: Used in high-performance insulation due to its low thermal conductivity.
-
Fireproof Materials: Included in fire-resistant composites and panels.
9 / Electronics
-
Encapsulation and Insulation: Provides electrical insulation and protection in electronic devices and circuits.
5 / Abrasive and Polishing Agent
-
Paints and Coatings: Acts as a thickener and anti-settling agent, improving the stability and flow properties.
-
Adhesives and Sealants: Enhances viscosity and prevents sagging or dripping during application.
-
Cosmetics and Personal Care: Used in creams, lotions, and gels to provide the desired texture and stability.
6 / Rheology Control
Rubber and Silicone Elastomers: Improves tensile strength, tear resistance, and abrasion resistance in products like tires, seals, and gaskets.
7 / Filler and Additive
-
Plastics and Resins: Enhances mechanical properties and reduces shrinkage in molded products.
-
Construction Materials: Improves the durability and workability of concrete and grouts.
8 / Anti-Reflective Coatings
-
Optical Applications: Used in coatings for lenses and screens to reduce glare and enhance clarity.
10 / Specialty Applications
-
Catalysts: Acts as a support material in catalyst production.
-
Nanotechnology: Used in producing nanoparticles and other high-performance materials.
