AEROSIL® fumed silica – Beneficial for optical properties
AEROSIL® fumed silica offers far more than brilliant prospects
Smooth, glossy surfaces
Keep a clear vision with AEROSIL® fumed silica
AEROSIL® fumed silica keeps silicone rubber colorless and ultra-transparent, yet allows for easy dyeing.
Ultra-transparent silicones are used for medical purposes, e.g. in tubes and catheters, but also for products of daily use such as baby bottle teats or diving goggles. AEROSIL® types with a highly specific surface area (e.g. AEROSIL® 300, AEROSIL® 380) are particularly suitable for these purposes.
The transparency of a silicone system can also be permanently improved by modifying the silica with functional silanes. AEROSIL® R 106 or AEROSIL® R 812 S are examples of modified, ultra-hydrophobic products that enable highly transparent applications.
Evonik also offers a number of functional silanes under the brand name Dynasylan®.
