Color Masterbatch: It is a colorant, usually in the production of thermoplastic products, according to the need to add different colors of masterbatch. Different materials and different colors to fill the proportion is not the same, as far as I know, not more than 10%.
 
   The basic requirements for plastic colorants:
 
(1) Good heat resistance (thermal stability)
 
(2) Good light resistance (light stability)
 
(3) good dispersion (that is, to cover the large)
 
(4) to be non-migratory (including solvent resistance)
 
(5) have a good tinting power
 
Masterbatch generally consists of three parts, the colorant carrier dispersant, through the high-speed mixer after mixing, crushing, extrusion into granulation, masterbatch in the plastic processing process, with high concentrations, good dispersion, clean And other significant advantages.
The use of color masterbatch has the following advantages:
1. make the pigment in the product has a better dispersion
Colorants in the production process to be refined on the paint to improve the pigment dispersion and color strength. The carrier of the special color masterbatch is the same as the plastic variety of the product, and has good matching. The pigment particles can be well dispersed in the plastic of the product after heating and melting.
2. It is beneficial to keep the chemical stability of the pigment
Direct use of paint, because the storage and use of the pigment in the process of direct contact with the air, the pigment will occur due to water absorption, oxidation and other phenomena, and made color masterbatch, the resin carrier will be pigment and air, water separation, can make the quality of the pigment long change.
3. To ensure the stability of the product color
Color Masterbatch particles and resin particles similar to the measurement is more convenient and accurate, the mixture will not adhere to the container, and the resin mixture is more uniform, so you can ensure the stability of the added amount, so as to ensure the stability of the product color.
4. Protect the health of the operator
Pigments are generally powdery, add and mix easily when flying, the body will be inhaled after the impact of the health of the operator.
5. Keep the environment clean
6. easy to use
The basic ingredients of the color masterbatch are:
Pigment or dye
Pigments are divided into organic pigments and inorganic pigments
Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, light red, macromolecule red, macromolecule yellow, permanent yellow, permanent purple, azo red and so on. Commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow and so on
2. carrier
Is the matrix of masterbatch. Special color masterbatch generally choose the resin with the same resin as the carrier, the compatibility of the two best, but also consider the carrier of mobility.
3. Dispersant
So that the pigment is evenly dispersed and no longer agglomerate, the melting point of the dispersant should be lower than the resin, and the resin has good compatibility, and the pigment has a good affinity. The most commonly used dispersant is: polyethylene low molecular weight wax, stearate.
4. Additives
Such as fire-retardant, brightening, anti-bacterial, anti-static, anti-oxidation and other varieties, unless the customer request, under normal circumstances the masterbatch does not contain the above additives.
What are the varieties and grades?
Color Masterbatch classification methods commonly used are the following:
By carrier classification: such as PE Color Masterbatch, PP Color Masterbatch, ABS Color Masterbatch, PVC Color Masterbatch, EVA Color Masterbatch and so on
According to the use of classification: such as injection masterbatch, blow molding masterbatch, spinning masterbatch and so on. Varieties can be divided into different grades
 
Toner: The company uses the world famous factory pigments, has been identified by SGS institutions, non-toxic in line with international standards. And configure MINOLTA computer color, color and other series of equipment. The company has more than experienced color matching technology, and the establishment of a professional customer service team, for color problems tracking service, all day to meet customer requirements for pigment toner, can be widely used in plastic blow molding, injection molding, plastic toys, electronics, electronics , Auto parts, wire and cable, home appliances shell, engineering plastics raw materials, silicone materials and other fields.
 
Toner is a common name for pigments and dyes. Toner series products include organic pigments, inorganic pigments, dissolved dyes, fluorescent pigments, pearlescent pigments, etc., widely used in plastics, paints, coatings, textiles, cultural and educational supplies and other industries.
 
An organic pigment
 
The general characteristics of organic pigments are: hue clear, good transparency, strong coloring, decentralized performance, resistance to migration, heat resistance, light resistance slightly worse, but with the development of new advanced organic pigments, so in plastic, paint, organic The application of pigments is becoming more and more extensive.
 
Two inorganic pigments
 
Inorganic pigments are usually metal oxides, sulfides, sulfates and other salts to carbon black, commonly used iron oxide yellow, iron oxide red, iron black, ultramarine, cadmium red and so are inorganic pigments, its production in natural, So there is a good heat resistance, light resistance and migration, cover ability, can be used for any plastic.
 
Three weight
 
 
 
According to the manufacturer of the composition of the weight, according to 25KG raw material units set the minimum purchase volume, and the toner does not depend on the weight to set the amount of raw materials that do not have different colors, each powder weight inconsistent, such as: TPE, PVC rubber PP, ABS, PS white, light gray relative to the proportion of heavy toner, and light, transparent color powder is the lightest proportion, usually used in small pieces of toner products, engineering plastics, transparent color , Silver.
