Antimony Trioxide Division

ANTIMONY TRIOXIDE: CATALYST GRADE

A high Purity grade used as a catalyst in the manufacture of Polyester (PET) Chips/Fiber/Yarn.

ATO accelerates the rate of esterification reaction & maintains the colour of the Polymer.

Salient Features of ATO Manufactured by IOCL are:

  • High Purity
  • Low Impurity Level of Heavy Metals like Pb, As Fe etc.
  • High solubility in Ethylene Gylcol
  • High ‘L’ & Low ‘b’ values

ANTIMONY TRIOXIDE: FLAME RETARDANT GRADE

ATO acts as a synergist with halogen containing compounds to impart Flame Retardancy in various Plastics.

Low addition levels of ATO effectively reduce the overall dosage of the Flame Retardant additives thereby reducing the deterioration of the physical properties of the plastics.

Applications: PVC, FR / FRLS Power Cables * Conveyor Belts * Unsaturated Polyester Resin * Masterbatches & Compounds
