What is Hydrophobic Fumed Silica?
Hydrophobic Fumed Silica (hydrophobic fumed silica), also known as Silphobic, is a highly dispersed fine powder composed mainly of silicon dioxide (SiO₂). It is produced by the gas phase method and has an extremely high surface area and unique chemical properties, making it widely used in various industries.
Product Features
1. **Hydrophobic**: The surface of Hydrophobic Fumed Silica has been specially treated to have excellent hydrophobicity, which can effectively prevent the adsorption of moisture. This makes it able to provide excellent moisture resistance in products such as coatings and sealants.
2. **High Strength and Stability**: This material has good mechanical strength and thermal stability, can maintain its performance under high temperature conditions, and is suitable for demanding industrial environments.
3. **Particle size and specific surface area**: Hydrophobic Fumed Silica's particle size is usually between 5-50 nanometers, with a large specific surface area (about 200-400 m²/g), which makes it excellent in thickening and strengthening applications.
4. **Compatibility**: It is compatible with a variety of organic and inorganic materials and is widely used in the formulation of a variety of substrates.
Application areas
- **Coatings and inks**: As a thickener and flow control agent, it improves the performance of coatings and inks.
- **Adhesives and sealants**: Improve thermal stability and water resistance, and enhance product durability.
- **Plastics and rubber**: Improve the physical properties of materials, increase tear resistance and abrasion resistance.
- **Cosmetics**: Commonly used to enhance product texture and improve spreadability.
Advantages
- **Improve product performance**: Due to its excellent physical and chemical properties, Hydrophobic Fumed Silica can significantly improve the performance of the final product and meet high-standard market demands.
- **Environmentally friendly**: As an inorganic mineral material, its relatively low environmental impact during production and use makes it a sustainable choice.
Conclusion
Hydrophobic Fumed Silica (Silphobic) is a versatile material that plays an important role in multiple industries due to its excellent properties.
