1.Antimony trioxide for Cable Material reacts with halogen flame retardants (such as chlorinated paraffins, decabromodiphenyl ether) to form SbCl₃ and SbOCl. In the gas phase,antimony trioxide for Cable Material captures free radicals (·H, ·OH) and interrupts the combustion chain reaction, enabling the wires and cables to pass through strict flame retardant tests such as UL94 V-0 and IEC 60332.
2.Plastic grade antimony trioxide is an electrically neutral inorganic substance. It is uniformly dispersed in cable materials such as PVC/PE, without affecting the volume resistivity (≥ 1×10¹² Ω·cm), and meets the insulation standard of GB/T 8815.
Key Benefits of Flame Retardant Antimony trioxide powder in Wires and Cables
Plastic grade antimony trioxide (Sb₂O₃) is a key flame retardant synergist widely used in the wire and cable industry. When combined with halogenated flame retardants, antimony trioxide for Cable Material significantly enhances fire resistance, ensuring compliance with stringent safety standards such as UL94, IEC 60332, and RoHS. This article explores the role, benefits, and applications of antimony trioxide for Plastic in wire and cable formulations.
1. Superior Flame Retardancy at Low Loading
Only 3-5% flame retardant Antimony trioxide powder is needed to boost halogenated flame retardants, reducing material costs while maintaining high efficiency.
Antimony trioxide for Plastic Enables oxygen index (LOI) values above 30%, ensuring self-extinguishing properties.
2. Excellent Electrical Insulation Properties
Unlike some organic flame retardants, Plastic grade antimony trioxide does not degrade volume resistivity (≥10¹² Ω·cm) or dielectric strength, making it ideal for high-voltage cables.
3. Thermal Stability for Processing
With a decomposition temperature >400°C, antimony trioxide for Plastic remains stable during PVC/XLPE extrusion (typically 160-200°C).
Plastic grade antimony trioxide Prevents premature degradation compared to hydrated fillers like aluminum hydroxide (ATH).
4. Cost-Effectiveness
Antimony trioxide for Plastic More economical than phosphorus-based or intumescent flame retardants, making it the preferred choice for mass-produced cables.
| Item | Appearance | Antimony Trioxide (Sb2O3) | Density | Sb2O3 content | Other content(ATH/MDH/DBDPE/CaCO3 /Zinc borate) |
| Antimony composite powder-80 | White powder | 99.80% | 3.73g/cm³ | 80% | 20% |
| Antimony composite powder-90 | White powder | 99.80% | 3.73g/cm³ | 90% | 10% |
Flame retardant Antimony trioxide powder remains a critical component in flame-retardant wire and cable formulations due to its cost-efficiency, synergistic effects, and electrical insulation properties.
