  Cas No. :10279-57-9 FEATURES AND BENEFITS
  
  Fumed silica process is to reuse the byproduct of silicon tetrachloride during the production of Polysilicon by adopting AEROSIL method, achieveing the close-loop circle during the process of Polysilicon-production and completely solving the environmental problem of silicon tetrachloride.
  
  Gas-phase white carbon black has wide industrial applications. It is fine reinforcing agent, filler and lubricant for the production of light-colored rubber and plastic products. It is an anti-settle agent for coatings, an ink dripping-preventing agent, a reinforcing filler for printing ink and bonding agent, and also the filler for synthetic resin, fiber, reinforced plastic, paper fiber, abrasive and paraffin. And it is also an anti-adhesive agent for White paint, pesticide and resin film. It is a dispersed matrix material of powder fire extinguishers and it is also used in the production of lubricant, so it is called “industrial Monosodium glutamate”.
