Fumed Alumina
Henan Xunyu ChemicalBase on fumed silica product, Xunyuchem developed the fumed alumina product. XYAL100 is a high purity aluminium oxide. It has high BET surface area and positive surface charge, which brings powerful functions in different applications.
Application and Functions
- Lighting industry: Fumed Alumina acts as binder between fluorescent materials, fluorescent materials and glass, makes them bidden together; as protect layer, keeps mercury from permeating into the fluorescent materials and glass, improve the lighting effect and extend the product lifetime
- Powder coating, toner: increase the flowability and charge ratio
- Photographic paper: increase the lustre and impressionability
- PP & PE: used as anti-blocking agent, prevent the plastic layer from bonding
