Masterbatch is one of the most important additives in the production process of plastic products, which is a combination of polymer base, pigment or special additives and carrier materials are used. The role of masterbatch is very key in improving the appearance, physical and resistance characteristics of plastics. In the Iranian market, there is a high demand for variety sales White masterbatch and black for plastic manufacturers in Tehran, because there are most plastic production units in this city They operate and need quality and sustainable raw materials.
The company Sarpolak is known as one of the reliable suppliers of plastic raw materials in Tehran, in the field of production and distribution of high quality white and black masterbatch.
What is masterbatch and why is it important?
Masterbatch is made as a combination of base resin (such as polyethylene or polypropylene) along with pigments and additives, which has the task of transferring color, resistance and performance to the final plastic product.
In the production of parts, films, pipes and packaging, the use of masterbatch causes:
- Saving the cost of painting
- Uniformity in the color and appearance of the surface
- Better thermal and optical stability
- Preventing the degradation of the base resin
On the other hand, choosing the type of masterbatch according to the type of polymer and its application is one of the important technical decisions in every production unit.
Masterbatch types in terms of color and application
Color masterbatches
These masterbatches include a variety of colors such as red, blue, yellow, green and other industrial colors. Among the most important of them, we can mention the blue pigment masterbatches (Blue 15:1 and Blue 15:3) and yellow (Yellow 12 and Yellow 13).
White and black masterbatch
Among all the colors, white and black masterbatch are the most used. The reason is high coverage, neutrality in compositions and light resistance. Sales of white and black masterbatches for plastic manufacturers in Tehran constitutes a significant part of the country's masterbatches market.
Additional masterbatch
This group includes anti-UV, anti-static, anti-fog, anti-odor and impact-resistant masterbatch that are used in certain industries.
What is white masterbatch and what are its features?
White masterbatch is one of the most widely used types of masterbatch, which usually contains a percentage of titanium dioxide (TiO2) as the main coloring agent. The percentage of this material and its dispersion in the masterbatch directly affects the color quality and brightness of the final product.
The main features of white masterbatch are:
- Very high covering power
- Resistance to UV rays
- Good thermal stability at extrusion temperature
- High compatibility with PE, PP and PS polymers
In Serpolak company, white masterbatch is produced with precise formulation and continuous quality control in order to create a shiny white color and prevent the product from yellowing due to light and heat.
Black Masterbatch and its uses
Black masterbatch usually contains Carbon Black with different percentages. In addition to coloring, this type of masterbatch also acts as a reinforcement of the structure of polymers.
Specific features of black masterbatch:
- High resistance to infrared and UV rays
- Increasing strength in pipes and technical parts
- Preventing brittleness against the environment and temperature
- Uniform color distribution without creating black or white spots
The most common use of this type of masterbatch is in polyethylene pipe, agricultural film, auto parts and industrial packaging industries. Relying on technical experience and quality raw materials, Sarpolk Company is one of the main suppliers of black masterbatch for plastic manufacturers in Tehran.
Why do plastic manufacturers in Tehran choose white and black masterbatch more often?
Tehran, as the main hub of plastic products production in the country, has hundreds of small and large production units. These companies are usually active in the production of plastic containers, nylon bags, pipes, injection parts and packaging products.
The reasons for preferring to buy white and black masterbatch from Serpolak company are:
- High color stability in mass production
- Competitive price compared to other suppliers
- Easy access to order and delivery in the shortest time
- Technical advice on choosing the type of masterbatch suitable for the polymer used
- Quality control according to international standards
Therefore, the growth of the market sale of white and black masterbatches for plastic manufacturers in Tehran is not unrelated to the quality policies of Serpolak Company.
Chemical composition and technical characteristics of masterbatch
Basic material
The base resins are usually polyethylene (PE), polypropylene (PP) or polystyrene (PS). The choice of each one depends on the type of application.
The percentage of pigments
In white masterbatch, the amount of titanium dioxide usually ranges from 40 to 75%. In black masterbatch, carbon black is from 25 to 50%.
Quality control
In Serpolak company, quality control is carried out from the input stage of raw materials to the output of the final product with spectrophotometer and melting test devices.
Advantages of using black and white masterbatch compared to direct color
Many manufacturers still use powder paint directly in the extruder or injection, but masterbatch has significant technical advantages:
- Uniform distribution in the polymer matrix
- Reduction of device pollution
- Exact control of color concentration
- Possibility of reproducibility of color in different production series
- No need for many changes in the formulation
For this reason, the target market of sale of white and black masterbatches for plastic manufacturers in Tehran is expanding.
The role of Serpolak company in Tehran's Masterbach market
Serpolk Company is known as one of the most reliable brands in the market with a long history of supplying plastic raw materials. With a central warehouse in Tehran and a nationwide distribution network, this company is able to meet the needs of all plastic manufacturers in the shortest time.
Advantages of cooperation with Serpolk company:
- Offering white and black masterbatch with export quality
- Technical support in choosing the right grade for film, tube or injection
- Guaranteeing color stability and product quality in each production batch
- Fast delivery to factories in Tehran and surrounding provinces
Industrial applications of white and black masterbatch
White and black masterbatch are used in different branches of the plastic industry:
- Packaging films: Creating a matte or glossy coating and preventing light from passing through
- Polyethylene pipes: Increasing resistance to sunlight
- Injected parts: Increasing color uniformity and surface smoothness
- Disposable containers: Creating a clean appearance and resistant to discoloration
- Agricultural equipment: Improvement Longevity of plastic outdoors
All these parts are regular customers of Sarpolak Company in Tehran, who trust the quality of white and black masterbatch of this company.
Important points in choosing the right masterbatch
- Compatibility of the polymer base: Selection of the masterbatch based on the type of polymer (PE, PP, ABS, etc.)
- Optimum consumption percentage: usually between 1 and 5% of the final weight of the plastic
- Processibility temperature: The masterbatch must work at the extrusion temperature without changing color
- Color spreading rate: The higher the dispersion percentage, the more uniform the color is
Technical team of Serpolak company guarantees the selection of the most suitable masterbatch for each production line by providing consultation and sample review services.
The future of Masterbach Bazaar in Tehran
Demand for buying and selling white and black masterbatches for plastic manufacturers in Tehran has an upward trend. The growth of packaging, agriculture and automotive industries has made more units to use high-performance masterbatches.
In the near future, the combination of multi-purpose masterbatches (with UV additive and anti-static at the same time) will become one of the main trends of the Iranian plastic market. In this way, Serpolk company has maintained its position as a technical reference by updating the formulation and using European pigments.
