BLIT Chemical manufacturer Antimony Trioxide CAS 1309-64-4, also known as Sb₂O₃, is a widely used inorganic flame retardant synergist designed to enhance the performance of halogen-based flame retardant systems. It is supplied as a high-purity white fine powder with excellent dispersion, thermal stability, and chemical consistency.

Antimony Trioxide does not act as a primary flame retardant but works synergistically with brominated and chlorinated flame retardants. During combustion, it reacts to form antimony halides, which effectively inhibit flame propagation and reduce heat release. This mechanism significantly improves fire resistance in plastics, rubber, coatings, and textile applications.

Thanks to its fine particle size and controlled purity, Antimony Trioxide from BLIT Chemical ensures reliable processing and consistent performance across a wide range of industrial formulations. It is commonly used in PVC, engineering plastics, cable insulation, adhesives, and coatings where fire safety compliance is essential.
