Title Tag: Precipitated Barium Sulfate – High Purity Functional Inorganic Filler for Coatings, Plastics & Printing Inks
Published Date: October 22, 2026
Shijiazhuang Huabang Mineral Products Co., Ltd launches high-quality precipitated barium sulfate, a premium inorganic functional filler engineered for global paint, coating, plastic, printing ink and powder coating manufacturers. Our precipitated barium sulfate features ultra-fine uniform particle size, high whiteness, low oil absorption and excellent chemical inertness. It can improve surface gloss, weather resistance and anti-settling performance of finished products, helping formulators reduce production cost while maintaining stable product quality. The product is available for bulk export. Each batch comes with full COA and MSDS documents to meet REACH compliance requirements.

This precipitated barium sulfate has high ISO whiteness, narrow particle size distribution. It does not interfere with pigment color development. When added into topcoat, powder coating and printing ink, it can enhance surface smoothness and high gloss performance. It is widely used in high-grade automotive coatings, industrial paints and architectural coatings.
Precipitated barium sulfate is insoluble in water, acid and alkali. It has outstanding resistance to UV radiation and weather aging. It can effectively extend the service life of coating films, and is ideal for outdoor coating systems requiring long-term durability.
With low Mohs hardness, it will not wear processing equipment during extrusion and injection molding. Adding precipitated barium sulfate into plastic and rubber can increase product density, improve rigidity, dimensional stability and sound insulation effect, commonly used in PVC, PP, PE profiles, sheets and rubber parts.
It is also suitable for adhesives, sealants, ceramic glazes and paper surface coating. Low heavy metal content makes it qualified for many environmental-friendly formulation systems.

Q1: What is the difference between precipitated barium sulfate and natural barite powder? A: Precipitated barium sulfate is chemically synthesized, with finer particle size, narrower particle distribution, higher whiteness and lower impurity. Natural barite is ground from mineral ore, with larger particle size. Precipitated grade is preferred for high-gloss coatings and fine ink systems.
Q2: Can precipitated barium sulfate improve the gloss of paint? A: Yes. Its ultra-fine uniform particles help form smooth coating surface, deliver excellent gloss and reduce surface defects, especially suitable for high gloss topcoat and powder coatings.
Q3: What is your packing and trade term? A: Standard package: 25kg multi-layer kraft paper bag with inner PE liner. We support FOB, CIF trade terms. COA and MSDS are supplied for each shipment for customs clearance.
Q4: Can you customize different particle size grades? A: We can provide custom D50 grades and surface modified precipitated barium sulfate. Free samples are available for customer lab formulation testing.
Global manufacturers of coatings, plastics and printing inks keep seeking stable, eco-friendly inorganic fillers. Our precipitated barium sulfate maintains excellent batch consistency and meets international environmental standards.
