Overview
Fumed Silica (ALITA-200)
Category：Auxiliary MaterialsCode：FUMED SILICA ALITA-200
Features
ALITA-200 is a hydrophilic fumed silica with a specific surface area of around 200 m²/g. Key properties include:
- Reinforcing Filler: Ideal for elastomers.
- Rheology Control: Acts as an efficient thixotropic agent.
- Anti-Settling & Anti-Sagging: Excellent thickening agent for liquid systems.
- Free Flow Aid: Prevents caking in powders.
- High Transparency: Maintains the visual clarity of the system.
