Masterbatch compared to other dyes, its dispersion, stability, operability is good for all of us to see, and its color of the bright and beautiful is captured the hearts of the masses. Then all this good, where is it? This is to start from the basic composition of masterbatch it!

The main component of masterbatch is composed of excessive chemical additives, carrier resin and dispersant. The masterbatch is a collection of supercharged pigments (dyes) that are uniformly attached to the resin. The masterbatch is mainly composed of a pigment, a dispersant and a carrier resin.

Masterbatch main ingredients:

01

Pigments or dyes: Pigments are also 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.

The same time as
Carrier: The carrier is the matrix of the masterbatch. Special color masterbatch generally choose the resin with the same resin as a carrier, the compatibility of the two best, but also consider the carrier's activity.

03

Dispersant: The evacuation agent promotes the average evacuation of the pigment and does not agglutinate. The melting point of the dispersant should be lower than that of the resin and has excellent compatibility with the resin, and the pigment has a good affinity.

The most commonly used dispersant is: polyethylene (PE) low molecular weight wax, stearate.

04

Additives: such as fire-retardant, brightening, anti-bacterial, anti-static, anti-oxidation and other varieties, unless the customer made a request, under normal circumstances the masterbatch does not contain the above additives.

As the pigment in the storage and use of direct contact with the air, so there will be moisture absorption, oxidation, agglomeration and other phenomena, the direct use of plastic products in the surface of the color point, hue dark, easy to fade color, and in the mixed Dusty, affecting the health of the operator.

The masterbatch in the production process through the mechanical processing, the pigment was refined, the pigment and resin carrier, dispersant fully mixed, so that the pigment and air, water isolation, thereby enhancing the pigment weather resistance, improve the The pigment dispersion and color strength, hue bright. As the masterbatch and resin particles similar shape, so the measurement is more convenient and accurate, mixed will not adhere to the container, thus saving the time to clean containers and machines and cleaners used in raw materials.
