The development history of color masterbatch
Color masterbatch is a new plastic and fiber coloring product developed in the 1960s. It is a composite of polymers obtained by uniformly loading pigments into resins. The color masterbatch is mainly composed of three parts: colorant, carrier and dispersant.

According to relevant information, the average annual growth rate of demand for color masterbatch in other countries in Asia is about 7%-9%, but the average annual demand growth rate for color masterbatch in my country is about 20%. China is expected to be the fastest growing market for masterbatch demand. Especially for color and additive masterbatch, our country has to rely on imports. my country has become the largest producer and consumer of the color masterbatch market in Asia. There are 330 enterprises producing color masterbatch in my country, of which there are 300 plastic-grade color masterbatch factories and 30 fiber-grade color masterbatch factories. These color masterbatch factories are mainly distributed in Fujian, Guangdong, Shandong, Zhejiang, Jiangsu and Shanghai. , Liaoning, Tianjin, Beijing, Hebei and other provinces and cities. There are nearly 50 enterprises with an annual production capacity of more than 1,000 tons of color masterbatch in my country. The national color masterbatch production capacity is 300,000 tons per year. In 2001, the demand for color masterbatch in my country was less than 120,000 tons. The serious excess of production capacity has led to the general under-operation of the domestic color masterbatch industry. In addition to factors such as the rapid growth of new production facilities and insufficient product orders, the important factors are that the domestic color masterbatch products have a single structure, incomplete varieties, and a large proportion of general-purpose products. The proportion of high concentration and ultra-high concentration, multifunctional color masterbatch and color masterbatch for fine denier fiber is less. On the other hand, countries with a high level of masterbatch technology have complete varieties of raw materials such as pigments and dispersants, and have formed a serialized and specialized product structure. In terms of variety development, my country's color masterbatch manufacturers have developed color masterbatch for fiber, color masterbatch for film, color masterbatch for wire and cable, polyolefin color masterbatch, PVC color masterbatch, and color masterbatch for injection molding products. Relevant experts believe that the color masterbatch will develop in the direction of multi-functionality, high color content and high-tech content in the future, and the development of color masterbatch will be accompanied by the improvement of production technology.
