1 Industry Background and Development
Polyvinyl alcohol (PVA) is a water-soluble high molecular polymer made by alcoholysis polymerization of vinyl acetate (VAM). It has unique properties, good strong adhesiveness, film flexibility, smoothness, Oil resistance, solvent resistance, colloidal protection, gas barrier properties, abrasion resistance, and water resistance with special treatment.
PVA has a wide range of uses. Downstream products include vinylon, paints, adhesives, fiber stocks, paper treating agents, emulsifiers, dispersants, films, medical materials, and construction automotive modified materials. Applications include textiles, food, and pharmaceuticals. , construction, wood processing, papermaking, printing, agriculture, metallurgy and other industries. New products and applications are still under constant development.
The performance of PVA is determined by its degree of polymerization, viscosity, and degree of alcoholysis. In general, the degree of polymerization is directly proportional to the viscosity index. Low-viscosity conventional grades such as 1799, 1899, 1788 are mainly used in downstream products such as emulsifiers, dispersants, fabric slurries, vinylon fibers, etc. High-viscosity grades such as 2099, 2299, 2499, etc. Highly demanding adhesives, cement improvers, architectural coatings, etc.
At present, the development trend of the world PVA industry is to develop at both high and low polarities, that is, the development of highly refined products with high degree of polymerization (high viscosity) and high degree of alcoholysis, and special products with low degree of polymerization and low degree of alcoholysis, the former being high Labeling adhesives, high-strength and high-filament fibers, cement reinforcements and other fields have good performance, while the latter are used for water-soluble adhesives and water-soluble fibers that have special requirements.
The PVA industry in China used Vinylon as the main target consumer market for a long time. In recent years, with the relative shrinkage of Vinylon consumption and the development of industrial applications, PVA non-fiber applications have been developed. A series of major strategic measures launched by the country in recent years to develop the central and western regions, build infrastructure and nurture the construction and real estate industries will effectively promote the further expansion of PVA industry applications. Table 1 shows the applicable fields of PVA product grades and representative brands.
