Method of Generating a Dispersion of Deagglomerated Barium Sulphate in Plastics or Plastics Precursors |
摘要 |
The invention discloses a method of incorporating deagglomerated barium sulphate having an average primary particle size of less than 0.5 mum and coated with a dispersant into plastics or precursors of plastics, for example into polyols. The deagglomerated barium sulphate is dispersed in an organic solvent, the dispersion is incorporated into the plastic or the precursor of the plastic, and the solvent is evaporated off.
