Antimony trioxide is a synthetic inorganic substance in the form of white crystals. Its chemical inertness and flame retardant performance constitute its main application value. Antimony trioxide exerts an inhibitory effect by interfering with the combustion chain reaction. It is usually used as a synergist in combination with basic flame retardant materials to enhance the overall fire resistance. In the field of industrial synthesis, it is widely used in the modification and processing of polymer materials based on its economic and material adaptability advantages.
The requirements for flame retardant properties in the electrical manufacturing industry have prompted antimony trioxide to be introduced into product construction. In the thermoplastic housing, protective insulation layer or high-temperature contact components of some electrical appliances, a thermal protection barrier can be formed by compounding this substance with a plastic substrate, which can delay the development of fire by forming a carbonized layer when exposed to high temperatures. Such applications are usually targeted at parts of the equipment that are prone to local high temperatures or arc risks.
The current actual application scale is limited by the continued development of alternative technologies. Environmental regulations and toxicity disputes have prompted some manufacturers to explore antimony-free flame retardant solutions and gradually reduce the proportion of this compound used. In addition, the diversity of material matching schemes in electrical appliance manufacturing determines that the existence status of antimony trioxide has significant industry heterogeneity, and its existence can only be confirmed through specific product ingredient analysis.
