## Fumed Silica: Versatile Additive for Enhanced Performance
Sensilchem's Fumed Silica is a synthetic, amorphous silicon dioxide, manufactured through the flame hydrolysis of silicon tetrachloride. It presents as a white, colloidal micro-particle powder with primary particle sizes ranging from 5-40 nm. Renowned for its exceptional properties, fumed silica is an indispensable additive across numerous industries, offering superior thixotropy, reinforcement, thickening, and anti-settling characteristics. It is insoluble in most solvents and liquids, except hydrofluoric acid and concentrated bases.
### Key Features & Benefits:
* **Excellent Thixotropy & Thickening:** Effectively controls viscosity and prevents sagging in liquid systems, ideal for paints, coatings, and adhesives.
* **Superior Reinforcement:** Enhances the mechanical strength, hardness, and durability of silicone rubber, plastics, and other materials.
* **Anti-Settling Properties:** Prevents pigment and filler sedimentation, ensuring homogeneous formulations and extended shelf life.
* **High Purity & Surface Area:** Offers a large surface area for chemical reactions and adsorption, enhancing product stability and performance.
* **Versatile Applications:** Suitable for a wide range of uses, from silicone rubber and coatings to pharmaceuticals and cosmetics.
### Applications:
Sensilchem's Fumed Silica is widely applied in:
* **Silicone Rubber & Sealants:** As a reinforcing filler to improve strength, hardness, and tear resistance in RTV and HTV silicone rubber, and various sealing materials.
* **Adhesives & Gels:** Controls viscosity, prevents sagging, and enhances bond strength.
* **Printing Inks & Toners:** Improves print quality, prevents pigment settling, and enhances toner flow.
* **Plastics:** Increases toughness, strength, and provides insulation properties.
* **Gel Batteries:** As a composite material to improve electrolyte retention and battery performance.
