The precipitated
barium sulfate has strong chemical inertness, good stability, acid
and alkali resistance, moderate hardness, high whiteness, high gloss
and the ability to absorb harmful x, γ-ray, as well as other
advantages. It is an environmentally friendly functional material. It
is widely used for a variety of coatings (water-based, oil-based and
powder coatings, such as automotive paint, wood paint, exterior wall
paint, anticorrosive paint, high-gloss paint, electronic ink and
printing ink, etc.), modified plastics (PA, PBT, PET, PC, POM, PMMA,
PP, ABS, PE, PS, automotive plastics, appliance housings, films and
building materials, plastics, etc.), rubber, elastomers, paper,
cosmetics fillers. It can also be used as the agent for **** stomach
when swallowed (called barium meal), the battery cathode expansion
rod, the glaze materials to manufacture ceramic and enamel, the
surface coating agent of printing paper and coated paper, the sizing
agent used in textile industry, the clarifying agent for glass, and
it can play part of defoaming and increasing the gloss effect. As an
anti-radiation protective wall material, it can be used in nuclear
facilities, atomic power plants and X-ray laboratories, etc. to
provide a good shielding effect. With the X-ray developing feature,
it can be used in the medical developing fiber and the children’s
toys. For drains, speakers and audio, it can effectively cut off the
noise. It can also be used in the synthesis of pharmaceutical
chemicals, and the flavors and pigments industry.
★ONMILLION
Products Features
The world’s highest whiteness
ONMILLION precipitated barium
sulfate has a high whiteness. Its L° value is generally higher than
99.5, the hue is bluish phase, and the b value is generally -0.20 or
so. Therefore, ONMILLION precipitated barium sulfate has high purity,
good weather resistance, acid and alkali resistance. It can keep
color neutral without affecting the downstream products while
guaranteeing the stability of the color.
Extremely good dispersion and stability at the international level
After a special surface
treatment, ONMILLION precipitated barium sulfate obtains a very good
dispersibility, and its blade fineness can reach 5μm or less, so the
coatings modified by ONMILLION precipitated barium sulfate has very
high gloss and thixotropy. In addition, it helps the pigment
dispersion, reduce the amount of pigment, and shorten the milling
time with cost savings.
Internationally advanced and leading particle size
distribution control technology
ONMILLION
precipitated barium sulfate has a narrow particle size distribution, and its particle size is controllable, so ONMILLION
precipitated barium sulfate has low
oil absorption, good gloss, and can be effective in reducing the VOC content. In addition, it can be prepared into thin coating products
with good processing stability. It has the function of reducing costs
and protecting the environment.
