Color masterbatch and functional masterbatch are essential raw materials in the modern plastic industry. With stable coloring performance, excellent dispersion, and strong material compatibility, modern masterbatch products can adapt to nearly all plastic processing techniques, including pipe extrusion, film blowing, injection molding, packaging production, courier bag manufacturing, fiber drawing, and wire and cable production. Choosing application-specific masterbatch ensures consistent color, stable physical performance, fewer production defects, and longer service life for finished plastic products.

1. Masterbatch for Pipe Extrusion

Pipe-grade masterbatch is specially formulated for PVC-U, PE, and PP water supply and drainage pipes. It features outstanding weather resistance, UV stability, and pressure resistance. Unlike ordinary masterbatch, pipe masterbatch does not affect pipe toughness or wall smoothness. It effectively prevents long-term outdoor fading, yellowing, and aging, making it ideal for construction drainage, municipal piping, and agricultural irrigation pipe systems.

2. Masterbatch for Film Blowing & Packaging

Film and packaging masterbatch adopts ultra-fine pigment technology with high transparency and uniform dispersion. It avoids crystal points, streaks, and fogging on thin films. Suitable for food packaging films, plastic wrapping films, and flexible packaging materials, this masterbatch supports FDA and food-grade compliance. It maintains film tensile strength and toughness while delivering bright, stable coloring for daily packaging products.

3. Masterbatch for Courier Bags

Courier bag masterbatch is designed for high-speed blown film production of express packaging. It has high color concentration, strong covering power, and low addition dosage. It adapts to rapid continuous production without causing film breakage or uneven color. Anti-blocking and anti-aging formulas ensure courier bags remain durable, scratch-resistant, and colorfast during logistics transportation and stacking.

4. Masterbatch for Injection Molding

Injection-grade masterbatch offers excellent fluidity and high-temperature resistance. It remains stable under 150–250℃ high-temperature molding, no discoloration or precipitation. Widely used for plastic housings, daily necessities, toy parts, and industrial accessories, it ensures uniform filling for complex molds and consistent batch color difference, improving the yield rate of injection products.

5. Masterbatch for Fiber Drawing

Fiber-grade masterbatch features ultra-fine particle size and ultra-high dispersion, specifically produced for plastic wire drawing, net weaving, and rope making. It avoids broken wires, fiber spots, and uneven yarn coloring. With high tensile retention, it guarantees the strength and texture of woven bags, plastic ropes, and industrial fiber products.

6. Masterbatch for Wires and Cables

Cable-grade masterbatch is halogen-free, low-smoke, and heat-resistant, matching the special requirements of wire and cable insulation and sheathing materials. It features anti-aging, anti-oxidation, and flame-retardant compatibility. It does not affect electrical insulation performance and is widely used for power cables, communication wires, and household wiring accessories.

Conclusion

Different plastic processing scenarios require customized masterbatch formulas. Professional application-specific masterbatch solves common industry problems such as poor dispersion, color fading, low strength, and high defect rates. Whether for pipes, films, packaging, courier bags, injection parts, fibers, or cables, selecting matched masterbatch significantly improves product quality, production efficiency, and market competitiveness for plastic manufacturers.
