  • Natural barium sulfate mesh is milledto a mean particle size between 8 and 12 microns. The product has a cream to off-white hue.


This product is a relatively soft industrial mineral with a high specific gravity. This property renders natrual barium sulfate an ideal weighting agent in paint, plastics and rubber.

Additionally, its light colour, low oil absorption and easy wettability in oils and resins permits natrual barium sulfate to be used in primers, paints, friction materials, rubber, carpet backing and radiation shielding for a variety of technical applications.

Natural barium sulfate is recognized for its radiation shielding properties allowing its use in X-Ray rooms, operating theaters and as a plaster adjunct for radiation emitting structures.
