Sabari® 40A series barite has a specific gravity of 4.35-4.40 g/cm³. Manufactured from carefully-selected high-purity raw materials, it features ultra-fine particle size, extremely low electrical conductivity and excellent chemical stability.

For electronic inks and PCB solder-mask inks, its ultra-fine, narrowly-distributed particles ensure smooth high-precision printing and sharp line definition, effectively avoiding printing defects caused by impurity contamination. Superior insulating performance and chemical-corrosion resistance satisfy stringent high-reliability requirements of the electronics industry.

It has outstanding chemical inertness and remains stable in ink systems without sedimentation or flocculation, guaranteeing consistent printing quality and batch-to-batch uniformity.
