Masterbatch | Types of masterbatches from Behin Polymer to improve the quality of polymer products

In the world of the polymer industry, masterbatches are known as one of the most widely used raw materials that play a decisive role in coloring, adding properties and improving the quality of polymer products. White masterbatches are used to produce transparent and bright parts, black masterbatches are used to create dark colors and protect against UV rays, and other masterbatches are used to improve properties such as heat resistance, anti-static or light stability. At Behin Polymer, we produce a diverse range of high-quality masterbatches.

What is a masterbatche and what is its use?

A masterbatche is a combination of a base polymer and a high concentration of a pigment or additive that is used in the form of granules in the plastics industry. This combination allows manufacturers to add color, specific physical and functional properties to polymer products without the need to change the original formulation of the raw material.
The use of masterbatches in the production process is increasing due to their ease of use, accuracy in adjusting the percentage of consumption and greater stability. This product not only helps to improve the appearance of the product, but also reduces costs and improves the performance of the final product.

Benefits of using masterbatches in the plastics industry

The use of masterbatches in the production of polymer products is not limited to the beauty of color or appearance. If you are designing or manufacturing a polymer product, knowing the benefits of this material can help you make a more accurate choice.
Next, we will review the most important advantages of using masterbatch:
• Improving the uniformity of color and additives: Masterbatch, with its precise combination of color or additive, causes uniform distribution throughout the product
• Increasing production efficiency: Using it in the form of ready-to-use granules is easy and fast and reduces production time
• Reducing workplace pollution: Since color or additive powders are supplied in the form of granules, dispersion and environmental pollution are less
• Ability to precisely adjust the percentage of consumption: Controlling the amount of color or additive is easily possible and material waste is prevented
• High compatibility with various polymers: Masterbatches are designed to suit the type of polymer and are technically fully compatible with the final product

Introduction to masterbatches

The diversity in application and technical needs has led to the production and supply of masterbatches in various types. Choosing the right type of masterbatch based on the final product and production conditions plays an important role in the quality and durability of the product. Let's get acquainted with the different types of this product.

Nucleating Masterbatch

Beta Nucleating Masterbatch is a specialized polymer additive used in the production of polypropylene (PP) to stimulate the formation of beta (β) crystals; by producing this unusual crystal structure, the impact strength and flexibility of the material are significantly improved. This masterbatch is added to polypropylene in granular form in very low doses (typically 0.1–2% by weight) and replaces part of the alpha structure by creating β crystal nuclei during cooling to increase the performance and durability of the final products without the need for expensive additives.

Processing Aid Masterbatch

Processing Aid Masterbatch improves the performance of production equipment. By reducing friction between the polymer and the surface of the mold or cylinder, the material flows more smoothly and the risk of tearing or jamming is reduced. The result is increased final quality and reduced production time.

Catalyst Masterbatch

Catalyst Masterbatch for the crosslinking process of PEX production is a combination of a polymer base (usually polyethylene) and crosslinking activating agents (such as silane derivatives) that are added to the polyethylene in granular form during pipe extrusion to controllably crosslink the polymer chains at the extrusion or curing temperature. This masterbatch, by uniformly distributing the catalytic agent at a specific temperature (usually between 160–220°C) and under appropriate pressure, causes the formation of a three-dimensional network (crosslink) in the polyethylene structure; the result is a significant improvement in the thermal resistance, chemical resistance and mechanical resistance of PEX pipes (especially in PEX-b), without the need for bulky additives or additional complex curing steps.

White Masterbatch

White Masterbatch contains titanium dioxide and is used to create high coverage and whiteness in products. Its application is very wide in the packaging, household appliances and sanitary ware industries. In addition to beauty, it also increases resistance to light and heat.

Black Masterbatch

Black Masterbatch is based on carbon black and is used to create a dark and uniform appearance. This type of additive not only provides an attractive color, but also ensures resistance to UV rays and increases the durability of the product. This product is
