St. Louis Group is one of the largest volume suppliers of antimony trioxide (ATO) in the US market. We are vertically integrated with mining and production operations in Bolivia and have contract manufacturing operations in China. Specialty dispersions and masterbatches are available upon request.
FireGard® SA has very low reactivity, low opacity, and affords excellent physical properties in thermoplastics and engineering resins, such as polyamide & polyester. It is not listed under California Prop 65 and has similar effectiveness to ATO.
