Composition：silicon stannate

Chemical formula：SiSnO₄

Application：The new inorganic environment-friendly halogen-free flame retardant can promote partial cross-linking and carbonization of the material to form a dense protective layer of carbon coke. This layer of coke can effectively block the release of volatile decomposition products and play a physical shielding role. It can be used as synergistic with halogen-based flame retardants. It plays the flame retardant role by reducing the thermal decomposition temperature of antimony oxyhalide (produced by the reaction of halogen with antimony trioxide), thus significantly improving the flame retardant efficiency, which makes it an efficient and inexpensive alternative to antimony trioxide.
