Product Description
Introducing barium sulfate into the coating of paper production can increase its gloss and fluidity, such as art paper and medium white transparent colored paper. The titanium dioxide part can be replaced with double barium sulfate without losing its gloss.
Natural Barium Sulfate
Natural barium sulfate, also known as barite powder, physical barium, or heavy barium, is made from natural barium sulfate ore (barite) through processes such as cleaning, polishing, and drying. Its chemical properties are very stable, insoluble in water, and resistant to acid, alkali, and non-toxic. It is widely used in the industrial field.
Precipitated Barium sulfate
Precipitated barium sulfate is a white amorphous powder with a relative density of 4.50 (15 ° C) and a melting point of 1 580 ° C. Because it has a high refractive index (1.63 ~ 1.65), it shows a whiter color and has a certain hiding power. It is almost insoluble in water, ethanol and acids, and soluble in hot sulfuric acid. It can be easily mixed with, calcium carbonate or metal nitrate. It can be reduced to with carbon at high temperatures. It is an important basic chemical raw material, the main uses: used as paint, paint, ink, plastic, rubber and battery raw materials or fillers; Surface coating agent for image printing paper and copper sheet paper; Sizing agent for textile industry; As a clarifying agent in glass products, it can play the role of defoaming and increasing luster. It can also be used as a protective wall material against radiation, and is also used in porcelain, enamel and dye industries

With the characteristics of low cohesion, low light dispersion and fine particles, barium sulfate is recommended for topcoats to increase surface hardness and color stability.
Barium sulfate has high filling properties and can be used in all coating series, such as primers, high-build coatings, etc. Its low specific surface area, particle size distribution and easy flowability make barium sulfate have low wear during processing. For its properties, barium sulfate is recommended for the surface layer of automatic primers, maintaining good uniformity and smoothness even at high fill levels.

Barium sulfate is used as a filler to increase the hardness of silicone rubber and reduce its elasticity. Barite powder below 500 mesh can be widely used in rubber products as filler to reduce costs, improve product hardness, acid and alkali resistance, and water resistance, and has a good reinforcing effect on natural rubber and synthetic rubber.
Used in the production of paper coatings, the introduction can increase its gloss and fluidity, such as white transparent colored paper in art paper. The titanium dioxide part can be replaced with double barium sulfate without losing its gloss. High-fineness barite powder can also be used as filler and coating filler for white paper and copper paper to increase whiteness and surface coverage. Product specifications: 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1250 mesh, 1500 mesh, 2000 mesh, 2500 mesh, 3000 mesh, 4000 mesh, 5000 mesh, 6000 mesh.
Thermal conductivity and ease of flow can reduce the injection molding time. Barium sulfate can be used as a nucleating agent to improve its strength and thermal stability. It can be used as a filler for plastic ABS raw materials to make the product shiny and bright, while also improving the product's strength, stiffness and wear resistance.
Barium sulfate has high purity, fine particle size and uniform distribution. It has excellent properties such as chemical inertness, acid resistance, high temperature resistance, corrosion resistance, high whiteness, high refractive index, and easy dispersion. It also has strong radiation absorption function and is used as an extender pigment. It is widely used in various types of advanced coatings, paints, inks and other industries. It is also widely used as filler in plastics, rubber, ceramics and friction materials. In addition, barium sulfate is used in drainage pipes, speakers, and stereos to effectively isolate noise and noise; when used in the casings of home appliances, it can provide high gloss, good color, scratch resistance, and good dimensional stability.
