Precipitated Barium Sulfate for Filler Industry

Molecular formula: BaSO4
HS code: 28332700
CAS No.: 7727-43-7
EINECS No: 231-784-4

PRODUCT DESCRIPTION:

Precipitated barium sulfate is a kind of material with environmental protection function due to its strong chemical inertness, Tire and rubber, insulation rubber, rubber plate, adhesive tape, engineering plastics can enhance the product anti-aging performance and climate resistance, the product is not easy to aging or embrittlement, and can significantly improve the surface finish, reduce the production cost. As the main filler of powder coatings, it is the main means to adjust the increase rate of powder bulk density.

ADVANTAGES:

Barium sulfate is commonly used as a filler for plastics to increase the density of the polymer in vibrational mass damping applications. In polypropylene and polystyrene plastics, it is used as a filler in proportions up to 70%. It has an effect of increasing acid and alkali resistance and opacity.

Barium Sulfate can effectively increase crystalline of thermoplastic polymer, so as to improve the strength and geometrical stability of products, Rubber Grade, Engineering plastic, polyphenylene sulfide (PPS) plastics,.
