Properties:
Antimony trioxide (English name Antimony trioxide) is a kind of pure white, the cubic crystal system of ultrafine powder, is one of the most stable of Antimony compounds. Molecular weight of 291.5, melting point 656 ℃, the cubic model (stable) density of 5.3 g/cm3. Antimony trioxide, antimony white, for both sexes oxide, insoluble in water, ethanol, dilute sulphuric acid and dilute nitric acid, but soluble in concentrated hydrochloric acid, sulfuric acid, tartaric acid and alkali solution.
Purpose:
1 antimony trioxide used in polyvinyl chloride, poly (PVC), polypropylene, polystyrene (PVC, ABS resin, polyester, polyurethane foam plastic products such as plastic, epoxy resin and phenolic resin and polypropylene, polyester and other synthetic fiber as a flame retardant synergistic agent. Flammable polymer according to certain proportion to join phosphorus-containing flame retardant and antimony trioxide association effect, can make the material burning oxygen index (OI, flame retardant effect is obviously enhanced, cost performance is good, is the most important inorganic flame retardant synergistic agent.
?2 passivation agent used as a rubber filler, petrochemical industry, glass clarify agent, coloring agent in ceramics, enamel, the production of optoelectronic components, solid lubricating materials and ship anti-fouling coating, and medicine, etc.
Packing:
Product use double bags, outer with outside composite paper-plastic bag, the inner with PE film bag, each bag net weight 25.0 kg, by playing into an tons a tray; High strength ton bag a ton a tray; Can also according to customer requirements for packaging.
