🔍 What Is Modified Nano Precipitated Barium Sulphate?
Modified Nano Precipitated Barium Sulphate is a chemically synthesized powder composed of BaSO₄ particles in the nanometer range, treated with surface-modifying agents (such as silanes, fatty acids, or polymers) to improve compatibility with organic systems.
Unlike natural or micronized grades, this version boasts:
Narrow particle size distribution (~100-200nm)
High purity (≥98%)
Low oil absorption
Excellent thermal stability
With its inorganic-inert base and organic surface treatment, it bridges the gap between functionality and processability.
