| Application | when used as a clarifier, the effect is particularly good with the use of nitrate. It can also be used to produce antimonate glass with good infrared transmission performance (3 μm) and low melting point (softening temperature 270~370 C) welding glass used in the electronics industry. In the enamel and ceramic industry is often used as a low-temperature glaze opacifying agent, underglaze color, glaze color, the composition of the glaze, antimony Blue, alkali yellow, white, green one of the components of the glaze. |
| flame retardant | flame retardants are a class of additives that improve the flame resistance of flammable polymers. The mechanism of flame retardant is very complex, and the flame retardant effect is achieved through various ways. Antimony oxide has little flame retardant activity when used alone, but has a synergistic effect when shared with halogen. Since polyvinyl chloride is a halogen-containing resin, flame retardancy can be obtained by using antimony oxide alone. When antimony oxide and chlorinated paraffin are used together, the flame retardant effect will be better. However, the use of antimony oxide after the product is opaque, so to a certain extent, limiting its use. The effective amount of antimony oxide is 1-5PHR, and the usual amount is 2-3PHR. At present, foreign countries have developed antimony oxide for transparent products such as Nyacol. |
| Main application | antimony oxide is widely used as flame retardant in pvc, pp, pe, ps, abs, pu and other plastics, the flame retardant efficiency is high, and the influence on the mechanical properties of the substrate is small (e. G., fire-resistant uniform and gloves, flame-retardant electronic equipment shell, flame-retardant cabin, flame-retardant wire and cable, etc.). In the rubber industry as fillers and flame retardants in enamel, ceramic products used as enamel covering agent in the electronics industry for the production of pressure-sensitive ceramics and magnetic head parts with non-magnetic ceramics in the coating industry as paint white pigments and flame retardants used as catalysts for organic synthesis of glass, used as glass fining agent in glass products |
