英文名称：High Light Barium sulfate
Molecular weight: 233.39 (according to the 1979 International Atomic Scale)
White powder, relative density 4.0-4.5, insoluble in water, acid, alkali and other solvents, but soluble in strong acid and concentrated sulfuric acid. Heat resistant, acid resistant, alkali resistant, non-toxic, tasteless can be used in contact with food products.
Good dispersion, high whiteness, good leveling. It has excellent light resistance, weather resistance and acid resistance. It has good chemical inertness and moderate surface energy, so that it has good dispersion and affinity with other media as a functional filler. And with all the color has good compatibility. Can replace part of the precipitated barium sulfate, titanium dioxide, active silica and other high-priced raw materials, reduce costs. It is an environmentally friendly material that can absorb harmful rays.
High-gloss barium sulfate is produced by special chemical synthesis process, special filtration technology and special surface treatment technology. It has the characteristics of high whiteness, no black particles, and good dispersion. This product is a white powder substance, non-toxic, tasteless, insoluble in water, acid, alkali and organic solvents, only soluble in hot concentrated sulfuric acid, and does not react with any gas. Therefore, it is a product with excellent weather resistance and corrosion resistance.
1, high whiteness, and titanium dioxide use coordination.
2. The particles are small and uniform, and the particle size distribution is narrow, which is similar to that of imported titanium dioxide.
3. After special surface treatment, it has good dispersion and high affinity with resin.
4, in the titanium dioxide particles between the isolation, so that titanium dioxide particles to protect each other
Hold a certain distance, give full play to the performance of titanium dioxide, improve the efficiency of the cover.
5, the product is pure, does not contain black particles, to ensure the purity of the product.
1, plastic, with good dispersion, can enhance the hardness and rigidity of plastic, maintain the surface gloss and brightness of plastic, especially suitable for the manufacture of high-gloss PP and nylon parts of home appliance shell.
In terms of powder coatings, it can enhance the leveling and gloss retention of powder coatings, and has good compatibility with all pigments.
