Base on fumed silica products, Xunyuchem developed the fumed alumina product. XYAL100 is a high purity aluminum oxide. It has a high BET surface area and positive surface charge, which brings powerful functions in different applications.
Application and Functions
- Powder coatings: Improve chargeability and flowability
- Li-ion Batteries: Increase the safety and life-time of ceramic coating for separators in Li-ion Batteries;
- Thermal insulation material: Shows high thermal and
chemical stability in Thermal insulation material,e.g. Vacuum insulation plate, etc; - Silicone and Composite materials: As filler for control density,heat conductivity and dielectric charateristics;
- Photo Paper: Provide high gloss and excellent printing;
- Melt-blown fabric of Mask: Used in electret masterbatch for improve the charge stability for better filtration efficiency of Mask;
