Product Description
EINECS No.: 231-545-4 Hydrophilic Fumed Silica Fumed Silica Nano Silica High Quality
Fumed silica (CAS number 112945-52-5), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles.
The versatility of our fumed silica is related to its wide range of surface areas and aggregate structure, both of which lead to unique performance benefits, including:
- Anti-settling, thickening and sag resistance
- Scratch and abrasion resistance
- Free-flow and anti-caking
- Corrosion resistance
- Enhanced adsorbency
- Reinforcement
Hydrophilic fumed silica function and application:
- Improve film physical and mechanical properties;
- Cardiac improve film adhesion and flexibility;
- Cardiac viscoelastic can improve rubber, elastomers, reinforcement;
- Derive the defoaming role of defoaming agent;
- Cardiac improve coating surface hardness, resistance to scratch;
- His film and elastomer in preventing adhesion;
- Adsorbent and carrier;
- Ink-jet printing coating;
- Senior dental material filler;
- Catalyst carrier, significant thermal insulation, used in low temperature and high temperature insulation.
