Masterbatch is a concentrated mixture obtained by dispersing pigments and additives into a polymer carrier through heat processing, particularly using high-shear mixing extruders. The mixture is then cooled, cut, and pelletized into granules through a pelletizing process. Masterbatch production places high demands on the compounding process, as pigments and additives must be uniformly dispersed throughout the base polymer.
White masterbatch is widely used in lamination, coating, pipes, thermoforming, protective films, fibers, nonwoven fabrics, blow molding, and injection molding. Advanced production capabilities enable the manufacture of high-quality indoor and outdoor white masterbatch using premium titanium dioxide (TiO₂) grades.
Titanium dioxide creates opacity by reflecting light due to its strong light-scattering ability. When light passes through TiO₂ particles, refraction and diffraction occur, causing light to scatter and reflect outward, resulting in an opaque appearance.
Advantages of White Masterbatch:
Excellent dispersion performance
Suitable for both thick-wall and thin-wall injection and blow molding applications
Easy to mix
Food-contact compliant

In recent years, the market for finished plastic products has grown rapidly. Product and packaging differentiation has become a key priority in the consumer goods industry. Rapid technological development and the continuous introduction of exclusive new pigments have helped expand market possibilities.
Color masterbatch has brought significant innovation to plastic resins and their various applications. These high-performance engineering thermoplastics provide vibrant, customizable colors that enhance product value while defining product appearance and functionality.
From industrial equipment and household appliances to textiles and packaging design, plastic processors rely on advanced color technologies. Thermal stability and color flexibility are two key reasons why color masterbatch is an ideal solution for plastic products. These masterbatches are produced using advanced pigments and are widely used in insulation cables, injection molding, blow molding, and many other processes.
Additive masterbatch helps prevent degradation caused by high temperatures and shear forces during processing, as well as UV radiation and oxidation in end-use environments. It can reduce fire risks and improve flame resistance.
Key control properties allow manufacturers to reduce product weight while using lower additive dosages, making synthetic material surfaces easier to print on or laser cut. In addition, additive masterbatch helps prevent static electricity buildup.
