Features & Benefits of Hydrophobic Fumed Silica LC-HFS500

It has excellent reinforcement performance when applied to the filling amount of silicone rubber.
Improve the free flowability of powder coatings.
The extremely low thickening effect and excellent operability make it have a high filling amount in polymers.
Has low thickening and good dispersibility in defoamers, improves defoaming speed, and prolongs defoaming time.
After deep processing, the structure is stable, and long-term storage can maintain the low moisture absorption rate of the powder.
Improve the powder coating rate of powder coating
As a dispersant in dry changing pigments and other pigments
Used as a reinforcing agent in plastic products and polymer materials
