Ethoxy (pentafluoro) cyclotriphosphazene is mainly used in electronic components (flame retardant additives for battery electrolytes, battery recycling fluids and flame retardant circuit board substrates), and can also be used to synthesize materials with high flame retardancy (flame retardant silicon core cluster tubes for communications, polyethylene/polycarbonate composites and inorganic/organic composite building materials). It is widely used in chemical production, electronic devices, multifunctional materials and other fields.
