2017 Development of Polyvinyl Alcohol Industry Market
According to the "China polyvinyl alcohol market operation situation and Investment forecast report (2017 edition)" published by the wood Information consultation, polyvinyl alcohol (PVA) is a water-soluble macromolecule polymer made from vinyl acetate (VAC), which is between plastic and rubber. According to its application field, products can be divided into two categories: fiber and non fiber. Because polyvinyl alcohol has unique adhesion, flexibility, solvent resistance, smoothness, oil resistance, gas resistance, wear resistance and special treatment of water resistance, etc., can be used in the production of paints, emulsifiers, dispersants, adhesives, paper additives, films and other products, in the textile, food, leather, construction, medicine, wood processing, paper, printing, agriculture and metallurgy industries have a wide range of applications.
At present, the global production of PVA in the major countries and regions a total of more than 20, the total production capacity of about 1.5 million T, since 2005, although slightly increased but lower. The Asia-Pacific region is the main production area of PVA products, while the remaining capacity is mainly from North America and Western. In the world's total production capacity of PVA, about 80% of production capacity from China, Japan and the United States, including the representative of the main manufacturers in Japan, Coca-Cola Company, China Petrochemical Group, China Chemical Group and Anhui-Victoria Group.
At present, the 3 enterprises with the largest production capacity of polyvinyl alcohol are China Petrochemical group Sichuan Vinylon Plant, Anhui Anhui Wigau New Materials Co., Ltd. and Shanxi three-dimensional group Co., Ltd., production accounted for 40% of the national total.
Although China's PVA industry after decades of development has made great progress, product variety is increasingly rich, but in the high precision, high value-added products and foreign industry compared with the larger gap. How to improve the technical level of high precision products and increase the added value of products is the main problem faced by PVA production enterprises in China, to improve the competitiveness of domestic PVA products in the international market, technological innovation is imperative.
