Color masterbatch is a mixture of resin and a large amount of pigment (up to 50%) or dye to form a high concentration color. Color masterbatch, also known as color variety, is an aggregate made by uniformly attaching super constant pigments or dyes to a resin.      

         The basic components of the color masterbatch are:

        1. Pigments or dyes: Pigments are also divided into organic pigments and inorganic pigments. Common organic pigments include phthalocyanine red, phthalocyanine blue, phthalocyanine green, light fast scarlet, macromolecular red, macromolecular yellow, Yonggu yellow, Yonggu purple, azo red, etc. Common inorganic pigments include cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.

        2. Carrier: It is the matrix of the color master batch. Special color masterbatch generally selects the same resin as the product resin as the carrier, with the best compatibility between the two, but also considering the fluidity of the carrier.

     3. Dispersant: Promotes uniform dispersion of pigments and no longer agglomerates. Dispersants should have a lower melting point than resins, good compatibility with resins, and good affinity for pigments. The most commonly used dispersants are polyethylene low molecular wax and stearate.

     4. Additives: Varieties such as flame retardant, brightening, antibacterial, anti-static, antioxidant, etc. Unless requested by the customer, generally the color masterbatch does not contain the above additives. There are several commonly used methods for classifying color masterbatches based on their variety and grade:  

Classified by carrier: such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc.

Each variety can be divided into different levels, such as:

       1.Advanced injection color masterbatch: used for cosmetic packaging boxes, toys, electrical casings, and other advanced products.

       2. Ordinary injection color masterbatch: used for general daily plastic products, industrial containers, etc.

       3. Advanced blown film color masterbatch: used for blow molding and coloring of ultra-thin products.

       4. Ordinary blown film color masterbatch: Coloring with blow molding of dry general packaging bags and woven bags.

       5. Spinning masterbatch: Used for spinning and coloring textile fibers. The masterbatch pigment has fine particles, high concentration, strong coloring power, good heat and light resistance.

       6. Low grade color masterbatch: used to manufacture low-grade products with low requirements for color quality, such as trash cans, low-level containers, etc.

       7. Special color masterbatch: It is a color masterbatch manufactured using the same plastic as the carrier according to the plastic variety specified by the user for the product. PPABS is selected as the carrier for PP masterbatch and ABS masterbatch, respectively.

          Universal color masterbatch: Some resin (often low melting point PE) is also used as a carrier, but it can be used for coloring other resins besides its carrier resin.

          The heat resistance level of specialized color masterbatch 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.

       9. Compared to granulation coloring, masterbatch coloring has the following advantages:

           9.1. Coloring and product processing are completed in one go, avoiding the heating process of granulation and coloring on plastic, which is beneficial for protecting the quality of plastic products.  

           9.2. Simplify the production process of plastic products.    

           9.3 It can save a lot of electricity.
