Product Description Polyvinyl alcohol (PVA)Introduction:Polyvinyl alcohol is a solid that can be white in powder, flake or flocculent form. Glass conversion temperature 60 ~ 85oC. Polyvinyl alcohol contains many alcohol groups, has polarity, and can form hydrogen bonds with water Chemicalbook, so it can dissolve in polar water. Polyvinyl alcohol can also dissolve in hot hydroxy solvents such as glycerol, phenol, etc., insoluble in methanol, benzene, acetone, gasoline and other general organic solvents.Packing: 25KGS in a kraftbag, each kraftbay has a plastic bag inside.Usage: Polyvinyl alcohol (PVA) is a widely used water-soluble polymer, PVA can quickly dissolve in water, forming a stable colloid, performance between plastic and rubber, in addition to fiber raw materials, but also widely used in the production of coatings, adhesives, paper processing agents, emulsifiers, dispersants, films and other products. The application scope covers textile, food, medicine, construction, wood processing, paper making, printing, agriculture, steel, polymer chemical and other industries.
