Barium Sulphate

---

■ Brief Introduction

Barium sulfate is a white powder with advantages such as strong chemical inertness, good stability, acid and alkali resistance, high density, moderate hardness, high specific gravity, high whiteness, and the ability to absorb harmful rays (X-rays and γ-rays) and other advantages.

■ Product Features

• Narrow particle size distribution, a small specific surface area and base material dosage, improve gloss and fluidity.

• Excellent chemical inertness, acid, alkali and salt resistance, high temperature resistance, aging resistance, corrosion resistance, good weather resistance.

• Improve the strength and aging resistance of products.

• Ultra fine barium sulfate can be used as a spatial spacer to reduce the dosage of titanium dioxide and improve the efficiency.

• Very low oil absorption, increase critical material volume concentration, save more resin base material.
