Antimony Trichloride is an inorganic compound universally used as a synergist in flame retardant formulations, particularly in halogenated plastics such as PVC and ABS. The Cl3Sb enhances the flame retardancy of polymers by interacting with halogenated compounds, improving thermal stability and smoke suppression. Also referred to as (Trichlorostibine, Antimontrichlorid, Caustic antimony, it is supplied in technical grade for industrial polymer applications. And particularly used as a reactant in many organic reactions. We are among the trusted Antimony Trichloride manufacturers and suppliers worldwide, with reliable lead times and global supply capability.
