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 growth rate of demand for color masterbatch in my country is about 20%. China is expected to become 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 color masterbatch market in Asia. There are 330 enterprises producing color masterbatches in my country, among 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, and the demand for color masterbatch in my country is less than 120,000 tons. Severe excess production capacity has led to the general underemployment of the domestic color masterbatch industry. In addition to factors such as excessive growth of new production equipment and insufficient product orders, the important factor is that domestic color masterbatch products have a single structure, incomplete varieties, and general-purpose products. The specific gravity, while the proportion of high concentration and ultra-high concentration, multifunctional color masterbatch and color masterbatch for fine denier fiber is relatively small. In contrast, countries with a high level of color masterbatch technology have a complete range 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 masterbatches for fiber, film, wire and cable, polyolefin color masterbatch, PVC color masterbatch, and injection molding products. Relevant experts believe that the color masterbatch will develop in the direction of multi-functionality, high color content and high technology content in the future, and the development of color masterbatch is accompanied by the improvement of production technology.
To make the pigments have better dispersibility in the product. In the process of masterbatch production, the pigments must be refined to improve the dispersibility and coloring power of the pigments. The carrier of the special color masterbatch is the same as the plastic of the product, and has a good match. After heating and melting, the pigment particles can be well dispersed in the plastic of the product.
It is beneficial to maintain the chemical stability of the pigment. If the pigment is used directly, the pigment will absorb water and oxidize due to the direct contact with the air during storage and use. After being made into a color masterbatch, the resin carrier separates the pigment from air and moisture. , can keep the quality of the pigment unchanged for a long time.
Guarantee the stability of the color of the product. The color masterbatch is similar to the resin particle, which is more convenient and accurate in metering. It will not adhere to the container when mixed, and the mixing with the resin is relatively uniform, so it can ensure the stability of the added amount, so as to ensure the color of the product of stability.
