One of the major growth drivers for Antimony is its dominant role in flame-retardant applications. Antimony trioxide is widely used as a synergist in flame-retardant systems for plastics, textiles and electronics—helping materials meet stringent fire-safety regulations. 
In parallel, lead-acid batteries continue to incorporate antimony in alloy grids for improved mechanical strength and life-cycle performance. Even as newer battery chemistries emerge, the legacy infrastructure for lead-acid remains sizable—thus sustaining demand for antimony. Combined, these application areas underpin a steady demand base for this critical material.
