Antimony Trioxide

The main purpose
1. For a variety of resins, synthetic rubber, canvas, paper, paint and other flame retardants, petrochemicals, synthetic catalysts. For the manufacture of mordant, white agent, antimony salt is synthesized. Enamel industry as additives to increase the opacity of enamel and surface gloss. Glass industry as a bleaching agent instead of arsenious acid. Pharmaceutical, metallurgical, military and other.
2. Antimony trioxide flame retardant additive belonging, often with other flame retardants, smoke suppressants and use, between the component may produce a synergistic effect. Antimony trioxide in the early stages of combustion, first molten material isolated from the air surface protective film is formed by an internal endothermic reaction, reducing the combustion temperature. Antimony trioxide is gasified at a high temperature, dilute the concentration of oxygen in the air, and thus play a flame retardant.
3. The polycondensation catalyst used in the polycondensation terephthalate in an amount of about 0.03%. Also used as various resins, synthetic rubber, canvas, paper, paint and other flame retardants. Antimony trioxide is also a good masking agents, used as a white paint pigment. For the manufacture of mordant, white agent, antimony salt is synthesized, glass industry substitute arsenic trioxide is used as decolorizing agent.
4. For fireproof coatings, paints, enamels and glass industry and preparing antimony potassium tartrate. Also used as a mordant.
