ABOUT MASTERBATCH


Polymer Usage History:
Usage of polymer has historically been have a lot of up-downs. By late discover of natural polymer and its development, it has been needed masterbach additives that polymer can be used for commercial usage and purposes. Additionally, both, the natural and artificial polymers need additive masterbach for dispersion. In this stage, both additive masterbach and resin are mixed in order to get to the standard application, and by adding these additives they can be used and ordered by customers.

What Is Masterbach?
In the polymer industry, masterbach is an intermediate element in order to get to the different desirable color that to be used as granule by compounding with raw materials for getting to the final products.
Masterbach Diversity/types: color masterbach, additive mastaerbach, expletive masterbach. These kind of masterbach are used by mixing with raw materials foundation, in order to get to the desirable and final products, based on the especial formula.

Masterbach Ingredient:
Pigments: they are color powder (pigment), mineral material (such as dioxide titanium and red iron oxide), or organic staple (like green Phthalocyanine) mixing with different percentages and diversity of color shade, and in most time, it is used in form of component in order to get to the final products in the masterbach formula.
Polymer Matrix: whereas pigment role is providing color and getting involve with raw materials in the first stage, it should be compound with a polymer based. Chosen a polymer based in PET matrix, is depend on the final product or raw materials that the color masterbach should be mixed.
Synergetic (adaptive) elements: with regards to the two mineral phases of (pigment) and organic phase (based polymer) and their antipiracy, there is needed an intermediator material for a proper mixing in the process of producing masterbach by the extruder machine. There need this dispersion to be happen very carefully, because these elements help the dispersion of pigments to be in a proper way. On the other hand, one of the procedures for development of the polymer industry is using additive masterbaches for getting to the best result of a chemical and even physical process of the final products.

Details of additive Masterbach:
1-Agent, it is in form of mineral material such (optical brightener), and anti-blocking and chemical, like (anti-static) which we could get to the desirable purposes by chosen the right agent.
2-Addaptive materials: in the adaptive materials formula, they are used additive and adjustments in order to get to the good result in the process of receiving to the final product.
3- Functional materials: Any additive masterbach is very important agent for plying its role in the product. So it is based on the proper polymer chosen for mixing agent and adaptor in order to get to the final proper product. The agents are so sensible and destroyer, they may be getting to the reciprocal results, therefore, there should be used adequate polymer for providing proper product to the market.

Specification of a Qualified Masterbach:
The important elements for chosen a proper masstarbach are as bellows:
-chosen pigment (color powder) famous proper agent,
-chosen a polymeric basic which can have a good mixing with additives and pigments.
-masterbach technical specifications: including dispersion capability in the process of using, moisture percentage (having drying and proper gassing process), melting degree, the same size, and brightness of the granules).
-low usage percentages,
-non-difficulty of grueling, structure effectiveness, impression on the products, good dispersion

Masterbach Using priority:
-Easiness of using in the process and resolving difficulties of using masterbaches and additives, getting to the best quality assurance,
-Color good mixing, elements better stability
-Improvement of melting process and mixing,
-Easy and low pricing of transportation and also proper using with Dozein systems,
-More cleanness of working environments, non- dissemination of powder in the air, keeping personnel healthy, preventing of recessional disease and poising materials,
-Percentages of color masterbach is based on the shape and forms,

Quantity or Weighting Percentages of Using Masterbaches:
Firstly, it is based on the number of existing agents and pigments, whatever using percentage is more, masterbach percentages decrease, and it is suitable for end-user. Therefore percentages and also quality of the additive elements is very important. Guarantee of the products (part), or filling, packing film (customer's elegance), important standards covering and passing the light from the products, in general. Additives percentages is from: 0.5% (in lubricants and anti-oxidants) up to 50% (in some delaying flame and carbonite calcium mastarebaches) also general percentages in the color masterbaches is different between %1 t0 2%.
