Product Description
Quality Hydrophilic Fumed Silica (EC-number: 231-545-4)
hydrophilic fumed silica products are used around the world to meet challenging performance requirements. Due to their unique particle characteristics, our hydrophilic fumed silicas provide superior performance benefits for many types of applications
HONON SILICON fumed silica can enable:
◆ Efficient thickening
◆ Low oil bleed
◆ Good reversibility
◆ No dropping point
◆ Water resistance
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.
