In the modern materials world, fire safety and mechanical durability are non-negotiable standards. Antimony Trioxide (ATO) from IRM is a leading solution, acting as a “gold” catalyst that optimizes performance characteristics for plastics, rubber, and high-end textiles.

Why is IRM’s ATO the preferred choice of global manufacturers?

We do not simply supply chemicals—we deliver purity and superior efficiency through strict technical specifications:

  • Optimal Whiteness: Ensures no color alteration in final products, even in light-colored or transparent plastics.
  • Ultra-fine particle size: Strictly controlled at micron level, enabling perfect dispersion in polymer matrices, enhancing flame retardancy without compromising mechanical properties.
  • Purity 99.5% – 99.9%: Completely eliminates harmful impurities, meeting the strict standards of semiconductor and electronics industries.

Versatile Solutions for Every Industry

Antimony Trioxide is one of the most important antimony compounds thanks to its exceptional versatility:

Sector

Role of IRM ATO

Value Delivered

Plastics & Polymers

Works with halogens to create gas-phase flame-retardant mechanisms

Prevents flame spread, protecting electronics and interior materials

Textile Industry

Flame-retardant treatment additive for curtains, aircraft/car seat fabrics

Enhances user safety while maintaining fabric softness

Glass & Ceramics

Fining agent in glass melting; opacifier in ceramic glazes

Synergistic Protection Mechanism

The true power of Sb2O3 lies in its synergy capability. When combined with halogen compounds, ATO generates free radicals that suppress flames at the ignition stage. It is an essential “weapon” in manufacturing household appliances and advanced electronic components, ensuring compliance with international fire safety certifications such as UL94.

“The quality of ATO determines the credibility of the final product. At IRM, we control every micron of particle size to guarantee absolute safety for your business.”
