The efficacy and function of functional masterbatches!

functional masterbatches is a granular compound made by mixing and granulating high proportions of functional additives, carrier resins and dispersants, etc. It is widely used in the processing of polymer materials such as plastics, fibers and films. Its core function is to endow the base material with specific functions or improve processing performance. The specific functions are as follows:

1. Endow materials with specific functions

This is the most crucial role of functional masterbatch. By highly concentrating and uniformly dispersing functional components (such as additives, pigments, auxiliaries, etc.), it enables originally ordinary polymer materials to acquire new properties:

Coloring function: Coloring masterbatch is one of the most common types. By mixing pigments (organic/inorganic pigments, dyes) with carriers, it can make the base materials such as plastics and fibers present uniform and stable colors, avoiding problems such as uneven dispersion, color difference, and equipment pollution caused by direct addition of pigments.

Anti-aging function: Anti-aging masterbatch contains antioxidants, ultraviolet absorbers and other components, which can delay the aging of materials caused by light, high temperature, oxidation, etc. (such as becoming brittle, fading, cracking), and extend the service life of products. It is often used in outdoor plastic products (such as agricultural films, pipes).

Flame retardant function: By adding flame retardants (such as brominated, phosphorus-based, inorganic flame retardants, etc.) to flame retardant masterbatches, the flammability of materials can be reduced, the spread of combustion can be suppressed or smoke can be decreased, meeting the fire protection requirements of fields such as electronics and construction.

Antibacterial and antifungal function: Masterbatches containing antibacterial components such as silver ions and zinc oxide can endow materials with the ability to inhibit the growth of bacteria and mold, and are suitable for medical devices, food packaging, bathroom products, etc.

Antistatic function: Antistatic masterbatch reduces the surface resistance of materials by introducing conductive components (such as carbon black, metal powder, and antistatic agents), decreases the accumulation of static electricity, and prevents static electricity from causing damage to electronic components and flammable and explosive products.

Barrier function: Barrier masterbatches (such as EVOH, PA, etc.) can enhance the material's barrier properties against gases (oxygen, carbon dioxide) and liquids (water, oil), extend the shelf life of food, and are often used in packaging films, containers, etc.

Filling and reinforcing function: The filling masterbatch contains fillers such as calcium carbonate, talcum powder, and glass fiber, which can reduce material costs and improve their rigidity, heat resistance, dimensional stability, etc. (For example, reinforcing polypropylene for automotive parts).

Second, improve processing performance

Improving production efficiency: The dispersant in functional masterbatch can help functional components be evenly dispersed in the substrate, reducing problems such as agglomeration and coking during processing, lowering the frequency of shutdown cleaning, and enhancing production continuity.

Simplified processing flow: Directly adding functional masterbatches eliminates the need for separate measurement and mixing of multiple additives, reducing raw material processing steps, lowering operational difficulty and errors, and is particularly suitable for automated production lines.

Protecting processing equipment: Some functional masterbatches (such as lubricant masterbatches) can reduce the wear of materials on equipment during extrusion and injection molding, and extend the service life of components such as molds and screws.

Iii. Ensure the stability of product quality

The content of functional components in the functional masterbatch is precisely controlled and evenly dispersed, which can avoid the performance fluctuations of the product (such as color difference and inconsistent flame retardant effect) caused by inaccurate measurement or uneven dispersion when directly adding additives.

For volatile and easily decomposable additives (such as certain antioxidants and lubricants), the carrier resin of masterbatch can play a protective role, reduce losses during processing, and ensure the effective performance of functions.

Summary

functional masterbatches, with their characteristics of "concentrating functions, simplifying processing, and stabilizing performance", have become a key means of modifying polymer materials. They are widely used in industries such as packaging, automobiles, electronics, building materials, and medical care, meeting the specific performance requirements of products while enhancing production efficiency and quality stability.
