White Carbon Black/Precipitated Silica
1.thixotropic agent &antisticking agent
2.High specific area
3.High oil absorption

White Carbon Black/Precipitated Silica

Features: 

  1. Good flow ability and high oil absorption precipitated silica. Recommend to use as carrier application. Good function to transfer any kind of liquid to free flow powder ,wildly use in feed industrial ,rubber aids agent ,coating powder aids agent and pesticide industrial .
  2. High oil absorb super fine silica ,sued as flow agent and anti caking agent in food and other fields .Toothpaste thickener .In a variety of liquid can be used as a thixotropic agent and thickening agent . Application :used as antisticking agent in food industrial and toothpaste thickener.
  3. A kind of silica produced by gel process with very high specific area and oil absorption ,which can party replace fumed silica in the silicon rubber goods by its good dispersion and matting property.
