Antimony Trioxide
Antimony trioxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions with hydrolysis.
The main application is as flame retardant synergist in combination with halogenated materials. The combination of the halides and the antimony is key to the flame-retardant action for polymers, helping to form less flammable chars. Such flame retardants are found in electrical apparatuses, textiles, leather, and coatings.
Antimony trioxide Mflam ATO is a white fine powder and the main crystal structure is of cubical shape.
What is Antimony trioxide?
Antimony trioxide is an additive flame retardant, which is often used with other flame retardants and smoke suppressants, and the synergistic effect can be produced between the components.
At the initial stage of combustion, antimony trioxide is first melted, forming a protective film on the surface of the material to isolate the air, and reducing the combustion temperature through the internal endothermic reaction.
At high temperatures, antimony trioxide is vaporized, diluting the oxygen concentration in the air and thus playing a flame retardant role.
1.High quality with best price
Widely used in PVC, PP, PE, PS, ABS, PU and other plastics as flame retardant, high flame retardant efficiency, small impact on the mechanical properties of the substrate (such as; Fire-resistant uniforms and gloves, fire-resistant electronic equipment enclosures, fire-resistant carriages, fire-resistant wires and cables, etc.).
Used as filler and flame retardant in rubber industry
Used as enamel covering agent in enamel and ceramic products
Non-magnetic ceramics used in the fabrication of pressure sensitive ceramics and magnetic head parts in the electronics industry
Used as a white pigment and flame retardant for paints in paint industry
Used as a catalyst for organic synthesis
