Knowledge of Color Masterbatch Details

1、 What is color masterbatch?

Color masterbatch is a new type of polymer material specific colorant. Simply put, color masterbatch is an aggregate made by uniformly attaching super constant pigments or dyes to a resin. 2、 What are the basic components of color masterbatch? The basic components of color masterbatch are: 1. Pigments or dye pigments are further divided into organic pigments and inorganic pigments

2、 The carrier is the matrix of the color masterbatch.

Special color masterbatch generally selects the same resin as the product resin as the carrier, with good compatibility between the two, but also considering the fluidity of the carrier. 3. The dispersant promotes the uniform dispersion of pigments and no longer agglomerates. The melting point of the dispersant should be lower than that of the resin, and it has good compatibility with the resin and good affinity with the pigment* The commonly used dispersants are polyethylene low molecular wax and stearate. 4. Additives such as flame retardant, brightening, antibacterial, anti-static, antioxidant, etc., unless requested by the customer, generally do not contain the above additives in the color masterbatch. 3、 What are the varieties and grades of color masterbatch? There are several commonly used classification methods for color masterbatches: classification by carrier: such as PE color masterbatch, PP color masterbatch, ABS color masterbatch, PVC color masterbatch, EVA color masterbatch, etc. Classification by use: special color masterbatches such as injection color masterbatch, blow molding color masterbatch, spinning color masterbatch, etc. The heat resistance level is generally suitable for the plastic used in products, and can be used with confidence at normal temperatures. Only in the following situations can it cause varying degrees of discoloration: firstly, the temperature exceeds the normal range, and secondly, the shutdown time is too long. Compared with granulation coloring, masterbatch coloring has the following advantages: coloring and product processing are completed in one go, avoiding the heating process of granulation coloring on plastic, and is beneficial for protecting the quality of plastic products. 4、 Why use color masterbatch? The use of color masterbatch has the following advantages: 1. Improving the dispersibility of pigments in products: Color masterbatch is an aggregate made by uniformly attaching super constant pigments to a resin. 2. Ensure the stability of product color 3. It is conducive to maintaining the chemical stability of pigments 4. Protect the health of operators 5. Keep the environment clean and do not contaminate utensils: 6. Simple process, easy color change, saving time and raw materials
