Advantages of Black Masterbatch

What is the black masterbatch?

The most shiny black masterbatch in Iran with Germany’s super shiny technology. The glossiness of this product revives waste materials in products such as garbage bags, injection parts and polymer sheets, as well as second-hand granules, and has a significant effect on the attractiveness and shine of new and luxury products. has more

Advantages of black masterbatch

  • Very low consumption percentage (700gr per 100kg)

  • Uniform spread and very high dispersion and prevent streaking

  • Absolute black color and complete coverage without passing light

  • Unique gloss for the first time in Iran

  • Polypropylene bags

  • Types of sheets

  • Car parts

  • Specialized compositions and…

Application of black masterbatch

  • Packaging films (types of nylon and garbage bags)

  • All injection parts

  • Disposable dishes

  • Polyethylene pipe and fittings and tip tape

Why use Armen Polymer black masterbatches?

  • The production of this masterbatch is done with fully customized machines and it has the ability to mix 50% of carbon black and pigment in the base polymer.

  • In Armen black masterbatch, polymer smoke and pigment are in a very fluid polymer matrix for further mixing.

  • In the formulation of this product, the help of specialized processes has been used in order to better combine and prevent clouding and airiness of the final product.

  • The consumption percentage of black masterbatch even in very low micron films is 700 per hundred kilograms.

  • The color of the final product is absolute black.

  • In customized grades, optimized pigments are used instead of carbon black, and the result is a super black product with a very high gloss and eye-catching.

  • The reason for the difference in the temperature of use and melting of black pigments and polymer is to prevent the destruction of the polymer and the weakening of the properties of the final product, the second generation antioxidant has been used in the black masterbatch.

  • Dyeing of your products takes place during the process with lower temperature and pressure.

  • Samples are sent and shipped for free.

  • Shipping is free.

Following the introduction of black masterbatch in the second part, we discuss the production process of black masterbatch in Armen Polymer Company.
Referring to some of the complications of the black masterbatch

  • Low coverage and use of high percentages for coloring

  • Creating dark and light streaks in the product

  • Create grains on the surface of the product

  • Getting the die and filters

  • Cloudiness and airiness of the final product

  • Polymer base incompatibility (wrong choice of polymer base)

  • Lack of gloss and eye-catching product

  • High cost price assuming the same raw materials but not having a proper process

The main stages of black masterbatch production

  • Formulation implementation stage

  • Feeding stage

  • Integration and mixing stage

  • Cooling and packaging

The implementation phase of the black masterbatch formulation

In the RD unit of Armen Polymer Group, with years of study and trial and error, in order to produce black masterbatch, first the suitable carbon black with the following specifications is selected.

  • The mesh is very high in soot

  • The percentage of purity and coloring of soot

  • Considering the effect of soot on the coefficient of elasticity (product elasticity)

  • Considering the effect of soot on tear and tension

  • Considering the impact of soot on product sewing and printing

Keep in mind that in addition to the role of coloring in some products such as water, gas and oil transmission pipes, soot plays the role of anti-UV against the sun’s rays, that is why black Meastricht is used, and also products such as

  • Ivory for tires

  • Types of tubes

  • Pressure and heat sensitive parts

  • Airplane tires

In addition to the selection of carbon black, the percentage of carbon black in the masterbatch and integration with the base resin is also determined according to the conditions and production technology. For the first time in Iran, Armen Polymer Company has been able to produce quality black masterbatch with 60% carbon black by strengthening the mixing department and auxiliary equipment of the production line. After carbon black, the selection of polymer raw materials or polymer base (polymer matrix) is done based on the following considerations.

  • Polymer base with suitable MFI

  • Compatible melting temperature

  • Good elasticity

  • Distribution power in the raw materials of the final product

Selection of very useful additives in the production of black masterbatch

  • Additive for compatibilizing and connecting the carbon black part with the polymer matrix

  • Mfi Suitable

  • Processing aid suitable

  • Optical brightener addtive

  • Antistatic to remove static electricity from the surface of the material and prevent dust and hair from being absorbed into the product

  • Antioxidant to prevent polymer degradation and loss of product properties

Feeding stage in masterbatch production

In this section, the components of the formula are coordinated according to the output flow rate of the device, the type of feeding and its methods are important and effective strategies in product quality.

Mixing and integration stage

The most important factor in the production of black masterbatch is the mixing stage and it is done in the following ways

  • Banbury mixers

  • Mixing extruder twin screw machine

Considering the importance of Banburi mixers as the best mixing method, especially in high percentages of soot, we will briefly introduce it.

Important parts of the Banburi device

  • Feeding part

  • Mixing part

  • Engine part

Banburi feeding part (black masterbatch production)

It includes a hopper to receive the material and a ram holder that keeps the mixing material within the effective operating range of the rotors (mardons).

Banburi mixing part (black masterbatch production)

This part consists of two interconnected cylinders, inside of which there are two spiral spirals called the rotor. It is formed that rotate opposite to each other. The cylinder and rotors are located in a cast iron housing.
In the name of the mixing chamber / mixing is done inside this chamber. For this reason, it is called an internal banbury mixer. Finally, the hydraulic door removes the mixed materials by opening and closing.

Banbury engine part

Internal reciprocating motor rotates the rotors, in this field, Siemens is very popular.

Why using indoor mixers in the production of black masterbatch is the best method

  • Much higher mixing power than extruders

  • Mixing without the risk of burns

  • High dispersion and distribution of carbon black in base polymer

  • Very effective in eliminating the common complications of Masterbatch (already mentioned)

  • Higher sewability in plastic films and inflatable products

  • Uniform coverage and prevention of overlapping and spot coloring

The final extruder stage using Banbury mixing method

After the mixing process, the material passes through another cylinder and mardon, and the preparation process for turning into granules and the cooling stage takes place.

cooling stage

By air-cooling or cooling tubs with a water circulation system, cooling water tubs that are installed from pools outside the production hall and cooling towers (water cooling towers) create stable conditions in hot and cold seasons. They cause the product to cool completely uniformly in stable conditions and it is effective in maintaining the quality of the product.

Masterbatch drying stage

At this stage, moisture and gas are separated from the product by a centrifuge. Note that at this stage, if the moisture of the material is not properly separated, it will cause holes and bubbles when using the masterbatch in the products.

Sifting step

After turning the raw product into granules and shaping by means of cutters or by string or watering process, which gives us two string or lens products, by means of a mesh screen that vibrates to sift the grains and separate them. It is in standard and uniform sizes. It is done for the purpose of preventing feeding problems for the final consumer.

Packaging stage

In the final stage of production, the products are packed with advanced equipment with a specific weight (usually 25 kg) in ffs or aluminum bags or multi-layer composite bags with the following purpose.

  • Prevent the penetration of moisture and dust

  • Proper thermal stitching

  • Resistant to impact and throwing

  • Better shipping
