Barium Sulfate: Pigment Aid, Filler, and Enhancer in Multiple Industries

Barium Sulfate: Pigment Aid, Filler, and Enhancer in Multiple Industries

Barium sulfate acts on titanium dioxide and pigments as gaskets in plastics to reduce the amount of pigment added and save about 10% of the cost.

Applying barium sulfate (about 25%) to the surface of PP is similar to ABS, and does not affect the existing characteristics of PPV, providing gloss and high hardness surface.

Barium sulfate can reach a filling rate of 80% of its weight. It can be used in drainage pipes, speakers, and audio to effectively isolate noise and noise. Barium sulfate can be used in curtains to increase weight. It can be used in the shell of household appliances to improve gloss, hue, surface scratch resistance, and dimensional stability.

Ultra-fine barium sulfate has an excellent isolation effect between particles of white or colored pigments, keeping the pigment particles at a certain distance from each other, improving pigment efficiency. In particular, the barium sulfate particles are tiny and have excellent performance. They can free the mesh gaps formed by titanium dioxide in inks and coatings, greatly improving the weather resistance of inks and coatings and improving the quality of paints. In addition, they have very few impurities and will not react chemically with organic substances in inks and coatings.

It can be used for acid-resistant rubber products and general products. It can also be used as a surface coating agent, sizing agent, weighting agent, etc.

Precipitated barium sulfate with a particle size of 0.7μm can resist flocculation and separate pigments, thereby reducing the amount of pigment to an extremely low value. Because in fact, the 0.7μm precipitated barium sulfate has no effect on viscosity
