synthetic barium sulfate
Product Features：
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.
Synthetic Barium Sulfate
Synthetic barium sulfate (BaSO₄) is a white, odorless, and chemically inert powder produced through a controlled precipitation process. Compared to naturally occurring barite, synthetic barium sulfate offers higher purity, consistent particle size distribution, and superior brightness. These properties make it an ideal functional filler in a wide range of industries.
Key Features:
High Purity: Free from harmful impurities and heavy metals
Excellent Whiteness & Brightness: Enhances visual appearance in end products
Narrow Particle Size Distribution: Improves dispersion and surface smoothness
Chemical Inertness: Stable in most chemical environments
High Density & Refractive Index: Offers optimal opacity and UV resistance
Common Applications:
Paints & Coatings: Improves gloss, weather resistance, and pigment dispersion
Plastics: Enhances rigidity, reduces shrinkage, and improves dimensional stability
Rubber: Provides reinforcement and maintains mechanical properties
Printing Inks: Ensures smooth texture and brilliant color reflection
Cosmetics: Acts as a safe, non-reactive filler for personal care formulations
Pharmaceuticals & Radiology: Used as a contrast agent for X-ray imaging (medical-grade only)
Synthesis Process：
Produce the nano barium sulfate with carbonate solution and sulfuric acid andcoated with special technology.
Application Areas：
Transparent filler masterbatch Car Paints
