Precipitated Barium Sulfate for Plastics
Barium sulfate is widely used as a functional filler in plastic masterbatches. It has high density, good chemical stability and excellent dispersion performance. It can increase the hardness, rigidity and weather resistance of finished plastic products, improve surface gloss and scratch resistance. Meanwhile, it helps reduce the production cost of masterbatches and maintains good processing fluidity during extrusion.
