Product Overview

MicroTalc® — Verified Talc for Demanding Applications

MicroTalc® is a range of micronised talc grades produced at our South African production partner's Benrose, Johannesburg processing facility — the same partner supplying our full mineral range. All grades are quality-controlled for chemistry, loss on ignition (LOI <6.0%) and particle size, and — most critically — the talc raw material is tested quarterly by an independent laboratory for asbestos (NIL detected) and heavy metals.

With 5 grades spanning a d50 range from 8.6μm to 12.1μm, MicroTalc® serves industrial filler applications across paints, industrial coatings, plastics compounding, rubber and construction.

  • ◆NIL Asbestos — raw material tested quarterly by an independent laboratory
  • ◆Heavy metals — screened quarterly; arsenic, cadmium and mercury below the laboratory quantitation limit (approx. 25 mg/kg)
  • ◆Mohs hardness 1 — the softest mineral on the Mohs scale; low wear on processing equipment
  • ◆Platey morphology — reinforcing function in plastics, barrier properties in paints
  • ◆Hydrophobic surface — ease of dispersion in dry powder formulations
  • ◆Electrical resistance (dielectric strength), UV and acid resistance
  • ◆5 grades providing formulation flexibility from fine to medium particle size range
