In the realm of material science and manufacturing, ensuring the fire safety of plastic products is paramount. This is where specialized additives like Antimony Trioxide (Sb₂O₃) play a critical role. As a trusted manufacturer and supplier of Antimony Trioxide, we understand the precise needs of the plastics industry. Our high-purity Antimony Trioxide, available as a fine white powder, is a cornerstone ingredient for achieving superior flame retardant properties, especially when synergized with halogen-containing compounds. If you are looking to buy Antimony Trioxide for your formulations, understanding its function is key to optimizing your products.

Antimony Trioxide's efficacy as a flame retardant synergist is well-documented. When combined with halogenated flame retardants, it forms a highly effective system that interrupts the combustion process. During a fire, Antimony Trioxide first melts, creating a protective barrier on the material's surface. This barrier physically isolates the material from oxygen. Concurrently, it undergoes an endothermic reaction, absorbing heat and lowering the combustion temperature. At even higher temperatures, Sb₂O₃ vaporizes, diluting the oxygen concentration in the surrounding air. This multi-faceted approach significantly inhibits flame propagation, making plastics safer for a wide range of applications, from electronics casings to construction materials.

The demand for reliable Antimony Trioxide continues to grow, driven by increasingly stringent fire safety regulations worldwide. As a leading Antimony Trioxide supplier in China, we are committed to providing consistent quality and competitive Antimony Trioxide price points. Our product, with CAS number 1309-64-4, is not only valued for its flame retardant capabilities but also finds use as a catalyst in petrochemical processes and synthetic fibers, and as an opacifying agent in the glass industry. Manufacturers seeking to enhance product safety and performance can confidently source our high-purity Antimony Trioxide.
