Antimony trioxide is an inorganic compound with the chemical formula Sb2O3. Natural products called antimony, commonly known as antimony white, white crystalline powder. Melting point 655 ℃. Boiling point 1550 ℃. Soluble in sodium hydroxide solution, hot tartaric acid solution, bitartrate solution and sodium sulfide solution, slightly soluble in water 370±37 μg/L, dilute nitric acid and dilute sulfuric acid. There is a carcinogenic possibility. There are two kinds of preparation methods, dry and wet, which are mainly used for white pigments, paints and plastics, and can play the role of pigments and flame retardants.

Antimony trioxide Sb2O3, also known as antimony white, is widely used as an auxiliary flame retardant for various synthetic materials because of its excellent synergistic flame retardant effect when combined with halogen flame retardants. Polyvinyl chloride itself is a halogen-containing polymer, which makes the application of antimony trioxide in flame retardant PVC plastics special and more common.

Antimony trioxide is mainly used as a flame retardant component of synthetic materials. In addition, it can also be used as a high-grade glass clarifying agent for picture tubes, fluorescent tubes, coatings, pigment additives (to improve water resistance, color persistence and flame retardant), heat-resistant colorants and glaze agents for enamel, ceramics, glass, alkaline dye mordant, petrochemical and synthetic fiber industry catalysts and raw materials for the manufacture of antimony salts.

Antimony trioxide is one of the general flame retardant synergistic agents. It is used as an additive flame retardant. When used alone, the flame retardant effect is very small (unless the flame retardant polymer already contains halogen). When used in combination with halogen flame retardant, the efficiency of halogen flame retardant can be greatly improved. It is a general flame retardant for polyethylene, polypropylene, polyvinyl chloride, polyester, polystyrene, epoxy resin, polyurethane and other plastics.

Antimony trioxide (also referred to as antimony oxide, commonly known as antimony white) molecular formula: Sb2O3 molecular weight: 291.5 Antimony trioxide is one of the inorganic flame retardants that have been used for a long time. It is mainly used as a flame retardant synergist to cooperate with halogen-containing compounds. It plays a flame retardant role in their thermal decomposition process and can replace some halogen compounds. It can be applied to plastics, rubber, chemical fiber, enamel, pigment, paint, glass, glass, electronics and other industries.

3.5 zinc borate water molecular formula: 2ZnO • 3B2O3 • 3.5H2O molecular weight: 434.51. Zinc borate is an inorganic additive flame retardant, which is characterized by good thermal stability, I .e. flame retardant and smoke elimination. It can replace antimony trioxide in some products and can also be used in conjunction with other inorganic flame retardants with better effect. Anhydrous zinc borate molecular structure formula is 2ZnO · 3B2O3, white powder, excellent fluidity, temperature resistance to 600 ℃, low heat release rate. Very low water solubility, no migration, and excellent charring performance, can be compounded with other additives into halogen-free expansion flame retardant, can be used as a high processing temperature polymer (polyether ketone, polyalum, polyester, nylon, fluorine-containing polymer, etc.) excellent flame retardant and smoke suppression agent.
