A detailed introduction to color masterbatches!

color masterbatches, also known as color seed, is a new type of colorant specifically designed for polymer materials. It is an aggregate obtained by uniformly loading an excessive amount of pigment or dye onto resin. Here is a detailed introduction about it:

Composition of components

Pigments or dyes: They are the core substances that give colors to products and can be classified into organic pigments and inorganic pigments. Commonly used organic pigments include phthalocyanine red, phthalocyanine blue, phthalocyanine green, etc., while inorganic pigments include cadmium red, cadmium yellow, titanium dioxide, carbon black, etc.

Carrier: It is the base of the color masterbatch. Generally, the same resin as the product resin is selected as the carrier, and the compatibility between the two is the best. At the same time, the fluidity of the carrier should also be considered, such as polyethylene, polypropylene, etc.

Dispersant: Its function is to promote the uniform dispersion of pigments and prevent them from coagulating. Its melting point should be lower than that of the resin, and it should have good compatibility with the resin and a good affinity for pigments. The most commonly used dispersants are low-molecular-weight polyethylene wax and stearate.

Additives: such as flame-retardant, brightening, antibacterial, antistatic, antioxidant and other varieties. Unless requested by the customer, the above-mentioned additives are generally not contained in the color masterbatch.

Characteristics

Excellent dispersibility: By adopting advanced production techniques and highly efficient dispersants, pigments are uniformly dispersed in the carrier resin. When mixed and processed with the base material, it can ensure uniform color distribution and avoid problems such as color spots and color patches.

High stability: It has good heat resistance, light resistance and weather resistance, can withstand high-temperature conditions in different processing techniques, and the color is not easy to fade. Some high-quality masterbatches also have migration resistance and are less likely to contaminate other items that come into contact with them.

Good compatibility: It has excellent compatibility with various base materials and can play a role in different types of plastic, rubber, chemical fiber and other products without affecting the physical properties and processing performance of the base.

Classification

General-purpose color masterbatch: Suitable for a variety of plastic substrates, it has wide applicability and can be used for coloring various plastics such as polyethylene, polypropylene, and polystyrene.

Specialized color masterbatches: Designed for specific plastic substrates, they offer better compatibility and coloring effects. For instance, specialized color masterbatches for polypropylene exhibit superior coloring performance and stability in polypropylene products.

Functional color masterbatch: In addition to the coloring function, it also has specific functions, such as UV resistance, anti-static, flame retardancy, etc. Uv resistance color masterbatch can effectively prevent plastic products from aging and discoloring when used outdoors.

Application field

Plastic industry: Widely used in various plastic products, such as plastic films, plastic pipes, home appliance casings, automotive interior parts, etc. Adding anti-ultraviolet functional color masterbatches to plastic films can extend their service life. The casing of household appliances uses high-gloss and anti-static functional color masterbatches, which not only enhance the appearance texture but also prevent dust adhesion.

Rubber industry: It can endow rubber products such as tires, shoe soles, and sealing rings with rich colors. Meanwhile, by adding corresponding functional color masterbatches, such as anti-aging and wear-resistant functional color masterbatches, the performance of rubber products can be enhanced and their service life can be prolonged.

In the chemical fiber industry: In the spinning and coloring of chemical fibers, the use of color masterbatches can produce various colored and special-function chemical fiber products, such as fibers with UV resistance and moisture absorption and sweat-wicking functions, which are used in the fields of textile and clothing, home textiles, etc.

Jiangsu Pulaike Hongmei Masterbatch Co., Ltd was established in 1990. It is one of the leading enterprises in China that has been engaged in the research and development, production, sales and service of high molecular composite coloring materials for a relatively long time. Currently, it is one of the larger polyolefin masterbatch producers in East China. With its strong technical strength, excellent product quality and good brand image, Hongmei Color Masterbatch will continue to stay close to the market, meet customer needs, maintain its long-term prosperity and lead the development of the industry.
