Polyvinyl Alcohol PVA in China
Nontoxic Polyvinyl Alcohol has biodegradable excellent performance, fully in line with modern society demands for environmentally friendly products, with good prospects for development. China is the largest country in the world PVA production capacity, production, consumption. Polyvinyl Alcohol domestic product differentiation rate is not high, the conventional product oversupply, while the larger part of the market demand for high value-added products have to be imported, for the future development of the domestic high-end products refined PVA has broad prospects.
Polyvinyl Alcohol production equipment and process complexity scale determines the stability of supply. Due to the long production process of Polyvinyl Alcohol, the number of devices and more complex production process, investment, technology and management is not easy to grasp, general corporate and investor difficult to produce.
Therefore, the state has not had a new factory building, just on the basis of the original device to transform the old supply -scale expansion of stability, to avoid disorderly competition in the market for the normal operation of the production provides favorable conditions.
Due to the rapid growth in consumption China Polyvinyl Alcohol, prices continued to rise, coupled with the rapid development in recent years, the domestic coal chemical industry, formed a gasification to methanol, methanol to acetic acid, acetic acid, calcium carbide acetylene and ethylene acetate, vinyl reproduction of Polyvinyl Alcohol product chain, making many coal chemical companies have development plans Polyvinyl Alcohol.
Growth in domestic GDP, increased textile exports, the rapid development of the construction industry, particularly the major downstream products remain relatively stable PVA fiber production growth, price volatility is not, for the formation of strong support polyvinyl alcohol industry.
There are usually two ways to produce Polyvinyl Alcohol. One is use ethylene as raw material, the preparation of Vinyl Acetate, and then prepared Polyvinyl Alcohol. The other is use Acetylene (divided into Calcium Carbide and Acetylene gas) for the preparation of raw material Vinyl Acetate, and then prepared Polyvinyl Alcohol. In Japan, the United States and other countries, usually produce Polyvinyl Alcohol used the ethylene as raw materials, namely oil and ethylene method. China has the most complete methods of production of raw materials of PVA.
