Barite Powder for Plastics

Product Characteristics

• Superfine particle size with a narrow and uniform distribution
• High purity with minimal impurities
• High whiteness for improved product appearance
• Excellent dispersibility in polymer systems
• Resistant to agglomeration for stable processing performance

Product Properties

Barite powder is a non-toxic white inorganic powder that is insoluble in water. It is soluble in concentrated sulfuric acid and slightly soluble in boiling hydrochloric acid. The material has stable chemical properties and can be reduced to barium sulfide when heated with carbon.

As a functional filler, barite powder improves the mechanical strength, weather resistance, and surface gloss of plastic products, making it ideal for high-performance polymer applications.

Applications / Usage

Barite powder is widely used as a filler in the following plastics:

• Polypropylene (PP)
• Polyvinyl Chloride (PVC)
• Acrylonitrile Butadiene Styrene (ABS)
• Polyamide (PA)
• Polyethylene Terephthalate (PET)

It enhances dimensional stability, surface finish, durability, and overall performance of plastic products.
