Antimony trioxide (Sb₂Oₑ) is an important inorganic compound and is widely used in flame retardants, catalysts, glass industry, pigments and other fields. High flame retardancy performance (core advantage) Halogen synergistic effect: Synergistic effect with halogen-based flame retardants (such as bromides, chlorides) significantly improves flame retardancy efficiency and reduces the amount of flame retardant used.
Gas-phase flame retardant mechanism: During combustion, antimony compounds (such as SbCl₃) are released to capture free radicals and interrupt the combustion chain reaction.
- Plastics (such as PVC, PP, ABS, polyester)
- Rubber (Wires and cables, automotive parts)
- Textiles (Flame-retardant fibers, fireproof coatings)
