Antimony oxide itself usually renders no flame inhibition properties to polymers, but it is known as a synergist for halogen compounds. The above reactions are considered to be as follow; *Br content, including 50-70% TBA derivative and Oligomer type. According to FLAME RETARDANT THEORY: Antimony oxide by itself is not a fire retardant, and the halogens by themselves, mainly bromine and chlorine, are weak fire retardants. It must be used in conjunction with a halogen source, for example, a brominated flame retardant.
