    Three, product use:

    1. Plastic processors use it as a synergistic flame retardant in thermoplastics and thermosets, and its end uses are in industries such as transportation, building and structural materials, electrical appliances, wire and cable, and furniture;

    2. Rubber processors use it in rubber hoses, transmission belts, carpet backings and other rubber products that require flame retardancy;

    3. Automobile manufacturers use it in PVC seat covers, carpets and other rubber parts under the hood or in the car;

    4. Synthetic fiber producers use it indirectly as a treatment catalyst, and antimony oxide is very important for the esterification of high molecular weight polyethylene terephthalate resins and fibers;

    5. Glass producers use it as a redox clarifying agent. In the process of glass coloring, antimony oxide reduces some metals (including iron, manganese, and chromium), which can reduce the valence state to obtain stronger glass color;

    6. Ceramic and glaze producers use it as a bright and transparent white colorant mixed in glass or oil, which is widely used in cast iron oil-ceramic bathtubs;

    7. Paint producers use it for flame retardant color white 11, and combine it with other metals to form color yellow 41, 53 and 118;

    8. Paper product processors use it as an essential ingredient in flame-retardant paper, which can be used as household insulation products;

    9. Chemical producers use it to grow a special FDA-approved stabilizer (an antimony thiolate) for PVC, and it can also be used as an intermediate for organic and inorganic compounds, fluorescent Firelight producers use it to activate a calcium halophosphate phosphor;

    10. Solid lubricant producers use it as a synergist for molybdenum disulfide, which plays a role in the field of aerospace industry lubrication.

    four, product packaging:

    The net weight of each bag is 25KG.
