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 during 390~780 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 mechanical property, 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.

Synthesis Process

◆ Produce the nano barium sulfate with carbonate solution and sulfuric acid and coated with special technology.

Application Areas

Plastics

Modified nano precipitated barium sulphate can be used in polymers to make compound materials with high strength and toughness, such as polyethylene (PE), polypropylene (PP), polylactic acid (PLA), and polytetrafluoroethylene (PTFE). It can effectively improve various mechanical performances of the plastics.

Paints

Nano barium sulphate plays a vary important role in making coatings – improving the thickness, abrasion resistance, water resistance, heat resistance, surface hardness, and impact resistance of the coating film. Due to its low oil absorption and high filling capacity, it can be used in water-based coatings, primers, intermediate coatings, and oil-based coatings to reduce the production costs. It can also replace 10%~25% of titanium dioxide in water-based coatings to increase its whiteness while remain the coverage.

Paper

Nano barium sulphate can be used to make paper with its advantages of good physical & chemical stability, moderate hardness, high whiteness, and the ability to absorb harmful rays, etc. Its high oil absorption value helps the paper absorb ink; the small particle size makes the paper more flat, and causes less wear on the machine.
