1. Product description:

Polyvinyl alcohol is a solid, which can be in the form of white powder, flakes or flocs. The glass transition temperature is 60~85℃. Polyvinyl alcohol contains many alcohol groups, is polar, and can form hydrogen bonds with water, so it can be dissolved in polar water. Polyvinyl alcohol is also soluble in hot hydroxyl-containing solvents such as glycerin, phenol, etc., but insoluble in general organic solvents such as methanol, benzene, acetone, and gasoline. Classification according to the degree of polymerization can be divided into ultra-high degree of polymerization (molecular weight of 250,000 to 300,000), high degree of polymerization (molecular weight of 170 to 220,000), medium degree of polymerization (molecular weight of 120,000 to 150,000) and low degree of polymerization (molecular weight of 2.5 to 35,000) ). The degree of alcoholysis generally has three types: complete alcoholysis (98-100% alcoholysis), partial alcoholysis (87Chemicalbook-89% alcoholysis) and 78% alcoholysis. In the product brand, the thousands and hundreds digits of the degree of polymerization are generally placed on the front, and the degree of alcoholysis is placed on the back. For example, polyvinyl alcohol 17-99 means that the degree of polymerization is 1.7k and the degree of alcoholysis is 99%. Application Polyvinyl alcohol (PVA) is a water-soluble polymer with a wide range of uses. PVA can quickly dissolve in water to form a stable colloid. Its performance is between plastic and rubber. In addition to being used as a fiber raw material, it is also used in large quantities. It is used in the production of coatings, adhesives, paper processing agents, emulsifiers, dispersants, films and other products. The application range covers textile, food, medicine, construction, wood processing, papermaking, printing, agriculture, steel, polymer chemicals and other industries .
