PRODUCT INTRODUCTION
Product Introduction
Barium Sulfate · High Whiteness & High Density · Chemical Inertness · Low Oil Absorption

Barium sulfate (BaSO₄) is a white powder with a density of 4.5 g/cm³, featuring strong chemical inertness, good stability, acid and alkali resistance, high density, moderate hardness, high specific gravity, high whiteness, and the ability to absorb harmful rays (X-rays and γ-rays).

Hico barium sulfate offers 3 series and 9 models: Native barium sulfate is ground from barite, offering high cost-effectiveness; Native high-whiteness barium sulfate is purified, with whiteness ≥88~91 and oil absorption as low as 8-12; Precipitated barium sulfate is prepared by chemical precipitation, with whiteness ≥94~98 and the finest particle size down to 0.1μm.

Barium sulfate has a narrow particle size distribution, small specific surface area and base material dosage, improving gloss and fluidity; very low oil absorption increases critical material volume concentration, saving more resin base material; can be used as a spatial spacer to reduce titanium dioxide dosage and improve efficiency.
