One, what is the color master?

Color masterbatch is a new kind of special colorant for polymer materials. To put it simply, the masterbatch is a kind of aggregate made by the uniform attachment of a large amount of pigment or dye to the resin. Second, what are the basic components of the color masterbatch? The basic components of the color master are: 1. Pigments or dyes pigments are divided into organic pigments and inorganic pigments

The carrier is the matrix of the color masterbatch.

The special masterbatch generally chooses the same resin as the product resin as the carrier, and the compatibility of the two is the best, but at the same time, the fluidity of the carrier should also be considered. 3. The dispersant promotes the pigment to disperse evenly and no longer condense, and the melting point of the dispersant should be lower than that of the resin, and has good compatibility with the resin and good affinity with the pigment. * Commonly used dispersants are: polyethylene low molecular wax, stearate. 4. Additives such as flame retardant, brightening, antibacterial, antistatic, antioxidant and other varieties, unless the customer requests, under normal circumstances, the color master does not contain the above additives. Which varieties and grades are divided into three color masterbatches? The classification method of color masterbatch is commonly used in the following ways: according to the carrier classification: such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc. According to the purpose classification: such as injection masterbatch, blow molding masterbatch, spinning masterbatch and other special color heat resistance grade is generally suitable for the plastic used for products, at normal temperature, you can rest assured. Only in the following cases will cause varying degrees of discoloration, one is that the temperature is out of the normal range, one is that the downtime is too long. Masterbatch coloring has the following advantages compared with granulation coloring: coloring and product processing is completed at one time, avoiding the heating process of granulation coloring on plastics, which is good for protecting the quality of plastic products. Fourth, why use color masterbatch? The use of master color has the following advantages: 1. Make the pigment have better dispersion in the product: master color is a super constant pigment uniformly attached to the resin and made of aggregates. 2. Ensure the stability of the color of the product 3. Help to maintain the chemical stability of the pigment 4. Protect the health of the operator 5. Keep the environment clean, non-polluting utensils: 6. Simple process, easy to change color, save time and raw materials
