Fumed Alumina

Henan Xunyu Chemical

Base 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
