Modified Nano Precipitated Barium Sulphate is a kind of the precipitated barium sulphate. It has high activation, ultrafine particle size, and can effectively improve the adhesion as well as other mechanical performances for the final products.


Modified Nano Precipitated Barium Sulphate is processed by delicate modification technology,it is widely used in high-end paints, inks, transparent functional filling masterbatches, automotive coatings, modified plastics, and so on.


  1. Small particle size less than 100nm,low scattering rate with very high transparency;
  2. High whiteness,it can maintain the stability of the color master for a long time;
  3. Low oil absorption,less carrier required,increases filler rate,thus reduce the cost;
  4. With the special surface modification technology,it has good affinity with various resins,it can reduce the addition of low molecular wax, and also improve mechanical performances;
  5. The high L value can guarantee high gloss and good brightness on the surface of the final products;
  6. Less impurity,toxic free and harmless,without halogen risk,it can ensure the final product safe and clean.
