Many masterbatches enterprise in the design of PE, PP, PERT, PEX color masterbatch on use of colorants insufficient understanding of, to the downstream customers caused by product discoloration problem, the fundamental reason is not clear, to the customer losses. So the design of color masterbatch for production of PE, PERT, PP, PEX, not only the pursuit of bright, to consider temperature - resistant, migration, fast, resistance to chemicals, toxicity, mixed and other factors. Plastic products enterprises in the selection of Color Masterbatch should also master some basic knowledge.
The precipitation problem will have quality problems in the blown film, CO extruded film products also. In the production of the product usually the ratio of raw materials for LLDPE 70% +LDPE30%, also have with metallocene increased membrane anti scratch and anti acupuncture. Selects the color masterbatch to consider matching problem, except of dispersibility and compatibility, heat resistance, light fastness, but also consider the precipitation problem, in which each link problems will influence the quality of the products. In particular, the production of vegetable packaging film, food packaging film, packaging film of children's activities, clothing membrane, sanitary napkins, diapers and other membrane materials, of masterbatch to avoid the precipitation of like is more important. In other words, blown film production enterprises to master certain knowledge of masterbatch, avoid problems at a loss, also can put forward the reasonable requirements of masterbatch production enterprises.
