Precipitated barium sulfate is a high-purity inorganic functional filler and extender pigment synthesized by chemical reaction. It is one of the most widely used inorganic raw materials globally, second only to titanium dioxide and iron oxide pigments. As a high-quality white inorganic pigment and filler, it is an essential raw material in building materials, coatings, plastics, rubber, ink and papermaking industries. It possesses core advantages such as environmental safety, high whiteness, weather resistance, acid and alkali resistance, and high cost-effectiveness. It features ultra-fine particle size, low oil absorption and excellent chemical stability, being a key raw material for high-end industrial manufacturing.
- Meticulous craftsmanship: Two production paths ensure controllable and traceable quality
- Natural mineral processing
Purified and processed from natural barite ore through crushing, grinding, flotation and impurity removal, retaining natural mineral stability, with affordable cost. It is suitable for general scenarios with high cost-effectiveness requirements, such as ordinary building materials, low-grade coatings and common plastic filling.
- Chemical synthesis
Employing precise processes such as chemical precipitation, filtration, washing, drying and ultra-fine grinding. Raw materials can utilize industrial by-products to achieve "waste-to-treasure" transformation, aligning with green production trends. The synthesized products exhibit high purity , uniform particle size, high whiteness and strong performance consistency, meeting the stringent requirements of high-end coatings, food contact materials, medical supplies and high-grade plastics.
- Core Features: Six Major Advantages Underpin "Abundant Value"
- Environmentally friendly and non-toxic, compliant and worry-free
Free of heavy metals and harmful substances, complies with EU REACH, RoHS and Chinese national standards, suitable for use in children's toys, cosmetics, food contact materials, medical and daily plastic products.
- Weather-resistant and lightfast, long-lasting and stable
Extremely strong UV resistance and aging resistance, will not yellow, fade or chalk for many years of outdoor use, suitable for high-temperature and humid rainy environments, making it a "long-life filler" for building exteriors and outdoor facility coatings.
- Acid and alkali resistant and corrosion resistant
Outstanding acid and alkali resistance, perfectly compatible with cement and lime systems; stable to strong acid, alkali and industrial chemical corrosion, making it the first choice for anti-corrosion coatings and chemical engineering materials.
- High whiteness and excellent hiding power
High whiteness and fine texture, with good extinction and filling performance. A small amount can improve coating fullness and covering effect, effectively replacing part of titanium dioxide, reducing material costs and maximizing cost-effectiveness.
- Good dispersibility and convenient construction
Superfine powder, easily dispersed evenly in water-based and solvent-based systems, suitable for various processing techniques such as coatings, concrete, plastics, rubber and ink production.
- Batch stability and controllable quality
Reputable manufacturers adopt the ISO 9001 quality management system, ensuring consistent whiteness, particle size and performance in each batch, avoiding production losses caused by color difference and unstable quality.
- Empowering all industries: From basic building materials to high-end manufacturing, covering all sectors
- Building Materials Industry
Colored concrete, floor tiles, roofing tiles: Improve compactness and weather resistance, keep stable color for a long time against sun and rain;Interior and exterior wall coatings, putty: High whiteness, good filling performance, environmentally friendly and crack-resistant after construction;Roads and infrastructure: Applied in traffic coatings and wear-resistant materials to enhance aging resistance and structural durability.
- Plastics and Rubber Industry
Pipes, toys, cables, shoe soles: High temperature resistant, dimensionally stable, meets environmental protection standards, suitable for high-grade plastic products and rubber accessories.
- Industrial Coatings and Corrosion Protection
Automotive paints and industrial coatings: Used as filling and extinction raw materials to improve coating hardness and durability;Shipbuilding, bridges, and steel structures: Core filler of anti-corrosion coatings to resist sea winds and moisture erosion and extend service life.
