Color type and color masterbatch are synonyms. Color masterbatch is referred to as pigment preparation, and it is a brand-new kind of unique colorant for polymer materials. Pigments, Colors, transporters, and additives comprise its three fundamental components. Color Masterbatch is an aggregate evenly disperses a consistent amount of pigment or dye in resin. This process is known as pigment concentration, and the total has higher coloring power than the pigment itself.
Ingredients of Colour Masterbatch:
Pigments or dyes:
There are two types of pigments such as organic pigments and inorganic pigments. The following organic colors are frequently employed, which include azo red, macromolecular red, macromolecular yellow, permanent yellow, permanent violet, and phthalocyanine red. Several inorganic pigments are commonly used, including cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.
Carrier:
Carrier is the masterbatch matrix. The compatibility of the two resins is best, but the carrier’s fluidity should also be considered. Special color masterbatches typically use the same resin as product resin and carrier.
Dispersant:
Promote uniform pigment dispersion and prevent pigment agglomeration. The dispersant’s melting point should be lower than the resin’s, and it should be compatible with the resin while also having a good affinity for the pigment. The most frequently utilized dispersants are stearate, low-molecular wax, and polyethylene.
Additives:
Unless the customer specifically asks for it, the above chemicals are typically not in color masterbatch for kinds such as flame-retardant, brightening, anti-bacterial, anti-static, anti-oxidation, and other varieties.
Uses of Color Masterbatch:
Improve The Dispersion Of The Pigment In The Final Product:
An aggregate known as a color masterbatch is created by distributing a highly consistent amount of pigment throughout the resin. In order to increase the pigment’s dispensability and tinting power, it must be polished during the color masterbatch production process. The carrier of the unique colour masterbatches matches the product’s plastic well. After heating and melting, the pigment granules can be thoroughly mixed into the product plastic.
Maintain The Colour Of The Product:
Resin particles are more accessible to meters, more precise, and comparable to masterbatch particles. When mixed with resin, the color masterbatch won’t stick to the container, and the mixing is more even. As a result, the consistency of the addition quantity can be guaranteed to ensure the stability of the product’s colour.
Contributing To The Pigment’s Continued Chemical Stability:
In direct contact with air during storage and use, the dye will oxidize and absorb water if utilized directly. Following the creation of the colour masterbatches, the resin carrier separates the stain from the air and moisture, potentially changing the pigment’s quality over time.
Final thoughts:
From the above mentioned, they will emphasize the importance of color masterbatch, its uses, and its advantages for many businesses. Combining additives and pigments enables colored plastics to acquire several additional properties.
