Choose Taixing for reliable antimony trioxide and other different types of . These products, with the chemical formula Sb₂O₃, can be used as flame retardants in plastics, textiles, and coatings. During thermal decomposition, they suppress flames by releasing water vapor and diluting flammable gases, thus improving fire safety.
Antimony trioxide is a white crystalline powder, an inorganic compound with good physical stability. Its density is between 5.2 and 5.4 g/cm³, which is a relatively heavy inorganic substance. The particle size is relatively fine, usually between 0.2 and 2 micrometers. It can be customized at Taixing according to actual needs. Smaller particle size helps with uniform dispersion in polymers and also allows for better reaction with the substrate.
Antimony trioxide has a high melting point, around 650°C, making it very suitable for use in high-temperature processing or high-temperature environments.
We can provide antimony trioxide with very high purity, ≥99.5%, and high whiteness, which does not affect the appearance of the polymer after addition, so you can use it with confidence.
Antimony trioxide itself is not a standalone flame retardant, but it is an important flame retardant synergist. We can also provide flame retardant solutions combining it with halogenated flame retardants or some phosphorus-based flame retardants.
When combined with halogenated flame retardants, such as Taixing's other product, , it reacts with the HBr produced by the decomposition of the halogenated flame retardant to generate highly volatile and highly flame-retardant antimony halide. This gas, once in the combustion zone, can more effectively capture highly reactive free radicals, resulting in higher flame retardant efficiency than when DBDPE is used alone. Furthermore, through synergistic use, the amount of halogenated flame retardant used can be reduced.
If you are looking for a customized flame retardant solution with phosphorus-containing compounds, antimony trioxide acts more like a solid-phase charring catalyst, promoting the formation of a char layer, especially for intumescent flame retardant systems, acting as a second layer of protection.
