Product Description Product DescriptionSodium metabisulphite is a white or yellow crystalline powder or small crystal with a strong SO2 odor, a specific gravity of 1.4, soluble in water, and the aqueous solution is acidic. When it is in contact with a strong acid, it releases SO2 to form a corresponding salt. When it is left in the air, it oxidizes. It is Na2S2O6, so the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.Standard:FCCCAS NO.:7681-57-4M.F.:Na2S2O5Specification: Tech. grade/Food gradeAppearance:White crystalline powderApplication: (1) Food Grade: Bleach agent (e.g. candies, cake, bamboo shoots, etc);, Loose agent (e.g. bread, cracker etc); Antisepticand germicide (e.g. fruit juice, tinned food, brews, the cereals food is defended storage etc); lnhibitor and freshen agent(e.g.daylily, seafood, fruit and vegetable etc).(2)Industry Grade: Mordant of printing and dyeing, Dechlorinate of textile afterbleaching, Sulphonated agent and reducer of chemical industry and pharmacy, Bleach of paper pulp, bamboo and timbelbleach of Stap, Treatment agent of waste water, Rubber solidifying agent Perfume industry is served as hydro carbonperfume aldehyde The hide profession employ to do to molt dose and pliable dose and wearproof dose, sewagetreatment, and so on .
