Product Overview

Microblanc® — High-Density Barium Sulphate

Microblanc® STD is a micronised barium sulphate (BaSO₄) produced at our South African production partner's Johannesburg processing facility — the same partner supplying our full mineral range. Its defining characteristic is high specific gravity (SG 4.10 g/cm³) — the highest of any mineral in the Elixir range — combined with BaSO₄ 93%, low oil absorption, light colour and easy wettability in oils and resins.

Microblanc®'s specific gravity (SG 4.10 g/cm³) sits below the SG 4.20 minimum specified for standard drilling-grade barytes, so it is best suited to its established use as a weighting agent in paints, primers, plastics and rubber, in friction materials and in radiation shielding applications.

  • ◆SG 4.10 g/cm³ — below the SG 4.20 minimum for standard drilling-grade barytes; suited instead to filler and radiation shielding applications
  • ◆High specific gravity SG 4.10 g/cm³ — the heaviest mineral filler in the Elixir range. Ideal as a density-enhancing filler
  • ◆BaSO₄ 93% — barium sulphate content (SiO₂ <1.0%, CaO <3.0%)
  • ◆Low oil absorption 12% — efficient filler loading with low resin demand
  • ◆Easy wettability in oils and resins — for a variety of technical applications
  • ◆Radiation shielding properties — used as a plaster adjunct for radiation-shielding structures
  • ◆d50 10.2μm — fine micronised grade
