Antimony Trioxide-Free Flame Retardant Solutions
Why Antimony Trioxide-Free Solutions Matter
Antimony trioxide-free flame retardant solutions provide a safer and more sustainable alternative to traditional ATO-based systems. By leveraging catalytic carbonization, gas-phase radical trapping, and condensed-phase protection, these ATO replacement formulations significantly reduce or eliminate antimony trioxide while maintaining exceptional flame-retardant performance. The system improves char layer stability, enhances LOI values, and effectively suppresses flame spread with lower additive loading.
Compared with conventional ATO formulations, ATO-free solutions dramatically lower toxic emissions and smoke density, helping manufacturers meet stringent environmental policies such as RoHS and REACH. The improved dispersion and compatibility of the formulation allow polymers to retain mechanical strength, color stability, and processing performance. This makes ATO replacement technologies ideal for electronics, home appliances, automotive plastics, and applications requiring safer and high-efficiency antimony-free fire protection.
Key Advantages of ATO Replacement Technology
Safer and Reduced Toxicity
ATO replacement systems eliminate heavy-metal risks and significantly lower toxic and corrosive gas emissions during combustion.
Enhanced Char Formation Efficiency
The synergistic catalytic design accelerates polymer charring and forms dense carbon layers that block oxygen and suppress flame propagation.
Superior Dispersion & Mechanical Retention
Compared with conventional ATO blends, optimized ATO-free formulations offer better polymer compatibility, ensuring minimal impact on strength, toughness, and color stability.
Better Combustion Efficiency With Lower Loading
ATO replacement solutions achieve comparable or improved LOI and UL94 V-0 ratings at reduced additive levels, improving cost-performance balance.
