Precipitated Barium Sulphate
The refractive index of this product is 1.64, same as most of the synthetic resin.and the particle size is nano grade, good transmittance of visible light during390-780 nm, the optical property is very good.
With special surface coated technology, low oil absorption, good distribution,good affinity with many kinds of resin, make the final product good mechanicalproperty, improve the filling rate, reduce the final cost.
High L value, could guarantee the final product high glossy and good brightness.
Without halogen, could guarantee the final product safety and cleanliness.
Synthesis Process：
Produce the nano barium sulfate with carbonate solution and sulfuric acid andcoated with special technology.
Application Areas：
Transparent filler masterbatch Car Paints
