There are many types of color masterbatch, which can be classified from multiple perspectives:
1. Divided by purpose
Universal color masterbatch: suitable for coloring various plastic products, with wide applicability, commonly used in various processes such as injection molding, blow molding, and extrusion.
Specialized color masterbatch: a color masterbatch specially customized for plastic products. Such as automotive interior parts, electronic product casings, etc., meet special color and pattern requirements, have a focused application range but can significantly improve product quality.
Functional color masterbatch: not only coloring, but also endowing plastic products with special properties such as heat resistance, cold resistance, anti-static, flame retardancy, etc., suitable for specific fields and having important application value.
2. Divided by color
Black masterbatch: widely used in plastic products that require black effect, such as automotive parts, electrical casings, etc., with stable color and strong covering power.
White masterbatch: filled with titanium dioxide, suitable for plastic products that require white or cover the original color, such as packaging boxes, cups, etc., with strong covering power.
Colored masterbatch: It enables plastic products to present rich and diverse colors, suitable for plastic products with diverse colors, such as children's toys, stationery, furniture, etc., with bright colors and uniform coloring.
3. According to the processing method
Injection molding masterbatch: suitable for high-end products such as cosmetic packaging boxes, toys, and electrical casings, as well as general daily plastic products, industrial containers, etc., with excellent processing performance.
Blow molding masterbatch: specially used for blow molding coloring of ultra-thin products or general packaging bags and woven bags, with uniform coloring effect and bright colors.
Spinning colorant: used for spinning and coloring textile fibers, with fine pigment particles, high concentration, strong coloring power, and good heat and light resistance.
4. According to the classification of carrier resin
It can be divided into PE masterbatch, PP masterbatch, PVC masterbatch, PS masterbatch, ABS masterbatch, EVA masterbatch, PC masterbatch, PET masterbatch, etc. Choosing the same resin as the product resin as the carrier can ensure the best compatibility and coloring effect.
5. Other classification methods
Classified by pigment type, it can be divided into organic pigment masterbatch and inorganic pigment masterbatch. The former has bright colors and strong coloring power, while the latter has excellent heat resistance and optical rotation resistance.
Classified by form, it can be divided into conventional masterbatch and liquid masterbatch to meet the needs of different processing techniques and products.
According to the principle of coloring, it can be classified into pigment colorants and dye colorants. The former has strong covering power and good light and heat resistance, while the latter has bright colors and high transparency
In summary, there are many types of color masterbatch, and when selecting, it is necessary to comprehensively consider various factors such as specific application scenarios, required colors, processing methods, carrier resins, and required functions to ensure the quality and performance of the product.
