竹原化学工業 List of Products and Services

"Barium sulfate" generally refers to the powdered form of the mineral barite, commonly known as natural barite, which is the ground product of barium sulfate (barite powder) and precipitated barium sulfate produced through chemical reactions. Due to its high specific gravity and its physical and chemical stability, it is widely used as an industrial raw material and inorganic filler in paints, plastics, and more. Precipitated barium sulfate can have its particle size controlled depending on the conditions during synthesis, allowing for the production of extremely fine barium sulfate. 【Features】 ■ High specific gravity (4.2–4.5) ■ Heat resistance (melting point 1580°C) ■ Chemical resistance (stable in acids and alkalis) ■ Radiation shielding *For more details, please refer to the PDF document or feel free to contact us.

The "NEOLIGHT series" consists of cubic colloidal calcium carbonate. It features extremely fine particles ranging from 0.03 to 0.15 μm (30-150 nm) and is of high purity. Surface treatment ensures high dispersibility. Functionalities can be imparted to the surface of colloidal calcium carbonate according to specific purposes, including improved dispersibility in solvents and resins, enhanced affinity and processability with solvents and resins, as well as the addition of viscosity and thixotropy. 【Features】 ■ Shape: Cubic ■ Extremely fine particles: 0.03-0.15 μm (30-150 nm) ■ Sharp particle size distribution ■ High dispersibility ensured by surface treatment ■ High purity *For more details, please refer to the PDF document or feel free to contact us.
