Synthesis Process of Modified Nano Precipitated Barium Sulphate:

Produce the Nano barium sulphate with carbonate solution and sulfuric acid and coated with special technology.


  1. 1.The refractive index of this product is 1.64, same as most of synthetic resin, and the particle size is nano grade, good transmittance of visible light during 390~780nm, optical property is very good.
    2.With special surface coated technology, low oil absorption, good distribution, good affinity with many kind of resin, make the final product good mechanical property, improve the filling rate, reduce the final cost.
    3.High L value, could guarantee the final product high glossy and good brightness.
    4.Without halogen, could guarantee the final product safety and cleanliness.

Widely used in transparent filler masterbatch, car paints, ink and modified plastics.

Packing: 25kg/Bag.
