Applications

  • Rubber accelerator – a thiazole accelerator for natural and synthetic rubbers (NR, SBR, BR, NBR), often used with a second accelerator.
  • Intermediate – the starting material for MBTS, CBS, TBBS and other benzothiazole accelerators.
  • Mineral flotation – a collector for sulphide and oxidised sulphide ores.
  • Lubricant additive – antioxidant and extreme-pressure component in lubricants and greases.

Packaging and documentation

  • 25 kg PP/PE bags and 1000 kg jumbo bags; palletised for container shipment.
  • Per-batch certificate of analysis (COA) and safety data sheet (SDS).
  • Keep sealed and dry; store away from oxidising agents.
