Masterbatch from a high proportion of pigments or additives and thermoplastic resin, a good dispersion of plastic coloring agent, the resin selected by the colorant has a good wetting and dispersion, and with the coloring materials have good compatibility. It has excellent coloring effect, convenient for automatic metering and transportation, energy saving, no dust, no pollution and other advantages, in plastics, paints and other materials in the application of color.
Development of Masterbatch
In other countries in Asia, the annual growth rate of masterbatch is about 7% to 9%, but the annual demand growth rate of masterbatch in China is about 20%. It is expected that China will become the fastest growing masterbatch demand market. Especially color and add masterbatch, our country depends on imports. China has become the largest producer and consumer of Masterbatch market in Asia. At present, our country masterbatch production enterprises have more than 400, mainly distributed in Guangdong, Zhejiang, Jiangsu, Shandong, Beijing, Shanghai, Hunan, Hebei and Tianjin and other provinces and cities, they belong to various industrial systems, of which the annual production capacity of more than 1000 tons of enterprises have more than 50, all over the country. and national color Masterbatch total demand less than 120,000 t, production capacity is serious surplus, leading to domestic masterbatch industry generally underemployment, market competition is very fierce. And these many masterbatch manufacturers, the quality of the few, and small and medium-sized enterprises and individual companies accounted for a large proportion. Excessive production capacity, in addition to the rapid growth of new equipment, product orders and other factors, such as the main factor is the domestic color Masterbatch product structure single, variety is not complete, general-purpose products accounted for a large proportion, and high concentration and ultra-high concentration, multi-functional masterbatch and fine denier fiber masterbatch accounted for less proportion. Anti-color Masterbatch high technical level of the country, pigments, dispersants and other raw materials, such as complete, has formed a series and specialized product structure. Foreign Masterbatch market is mainly concentrated in Western Europe, North America and Japan, the production of color Masterbatch enterprises are multinational companies or the world's top 500 enterprises, such as the United States Hanna, Poiyone, BASF, Hoechst, Rui soil Ciba-geigy, giarant and other companies, annual output of more than 1 million tons, Western Europe accounted for more than 50%, Hanna Company sales of 140,000 tons a year.
