In the pursuit of enhanced product safety, particularly in materials susceptible to fire, the selection of effective additives is paramount. Antimony Trioxide (ATO) has long been recognized as a cornerstone synergist in flame retardant systems, essential for achieving stringent fire safety standards across numerous industries. NINGBO INNO PHARMCHEM CO.,LTD. stands as a premier manufacturer and supplier of high-purity Antimony Trioxide (99.8%), providing the essential building blocks for advanced flame retardant solutions. This article highlights the importance of ATO and the benefits of sourcing it from a trusted provider.

Antimony Trioxide (CAS No. 1309-64-4) is a fine, white powder that plays a pivotal role when combined with halogenated compounds. Its primary function is to amplify the flame retardant properties of these systems. Under thermal stress, ATO initiates a cascade of chemical reactions that interrupt the combustion cycle. It reacts with halogens to form antimony halides, which then act in the gas phase to scavenge highly reactive free radicals that propagate flames. Concurrently, it can promote char formation on the material’s surface, creating an insulating barrier that hinders heat and oxygen transfer. This dual-action mechanism significantly improves a material's fire resistance, making it an indispensable component for a wide range of products.

The applications for our high-purity Antimony Trioxide are diverse and critical. In the plastics industry, it is extensively used to enhance the flame retardancy of polymers such as PVC, PP, PE, PS, ABS, and PU. This is crucial for components in electronics, automotive parts, construction materials, and wire and cable insulation, where meeting fire safety regulations is mandatory. Beyond plastics, ATO also serves the rubber industry by providing fire resistance, and it is employed in paints and coatings as a white pigment and flame retardant. Its utility extends to glass manufacturing as a clarifier and to the ceramic industry for enhancing glaze properties.
