Nowadays, plastic products are more and more widely used in various industries. In order to eliminate the pollution caused by dust emission and improve the production environment in the plastic processing process, color masterbatches are more and more favored by users. The masterbatch also contributes to colorant dispersion and color consistency, which is beneficial to improving product quality and equipment utilization.

Below we introduce the application of several masterbatches in different industries.

Application of masterbatch in packaging film: plastic film is soft, transparent, and has a low density, which can reduce packaging weight and facilitate transportation, and has certain strength and aesthetics. Therefore, plastic packaging materials have replaced traditional packaging materials. Color masterbatch is used in a large amount in polyethylene blown film. According to the different processing conditions of different resins, the general requirements for its masterbatch are good dispersibility, less impurities, no discoloration, and bright colors.

Application of color masterbatch in cast composite film: cast film has the characteristics of good plasticization, smooth surface and good mechanical strength. Its processing temperature is relatively high, so the pigment used in the masterbatch is required to have good heat resistance and no migration.

Application of color masterbatch in blister sheet: The main color of blister product is transparent and various white, but there are also a small amount of ivory yellow, brown and other color masterbatches in the blister sheet to be uniformly dispersed, without impurities and Moisture.

Application of color masterbatch in packaging container (hollow blow molding): In the hollow blow molding process, the processing and application of color masterbatch should be considered, and special attention should be paid to pigment dispersion, heat resistance, chemical resistance, and light resistance. Properties such as sex and toxicity.

Application of masterbatch in foam molding process: If the process is directly colored with pigments, a large number of pores will be generated on the surface of the product after foaming, which will affect the value of the product. At present, a large number of masterbatches have been used, which has become a new category of masterbatch applications. . In the process of use, pay attention to the dispersibility of the masterbatch, and there should be no impurities in the masterbatch.

Application of color masterbatch in the injection molding process: different plastics have different molding temperatures, so the pigment requirements in the color masterbatch are also different. In the use of injection molding, pay attention to the dispersibility of the masterbatch, and use a carrier with good compatibility.
