Additive masterbatch is a pellet compound made by mixing carrier resin, high-concentration functional additives and processing aids via melt blending and granulation. It is added to raw plastics to improve processability, physical properties or service performance.

2. Difference from color masterbatch

Color masterbatch only focuses on coloring; additive masterbatch focuses on functional modification, not changing color mainly.

3. Common Categories & Functions

Toughening masterbatch: Boost impact resistance and low-temperature toughness.
Clarifying masterbatch: Improve transparency and gloss of plastics.
Anti-block masterbatch: Prevent films or thin products from sticking together.
Anti-fog masterbatch: Stop fog and water droplets on film surfaces.
Anti-UV / Weather-resistant masterbatch: Resist UV rays and aging for outdoor products.
Anti-static masterbatch: Reduce surface static electricity, avoid dust adsorption.
Flame retardant masterbatch: Make plastics fire-resistant.
Lubricant / Processing masterbatch: Improve fluidity, ease molding and reduce wear.
Degassing masterbatch: Remove bubbles and moisture during processing.

4. Main Advantages

High concentration, accurate dosing and easy proportion control.
Dust-free, safer and cleaner than direct use of powder additives.
Additives disperse evenly, stable performance in mass production.
Convenient storage, transportation and automatic feeding.
Reduce formula complexity and simplify production.

5. Applications

Widely used in PE, PP, PVC, ABS, PS, biodegradable plastics for films, injection parts, pipes, cables, packaging, auto and electronic products.

6. Usage Tips

Select the masterbatch with carrier resin compatible with your base plastic.
Follow recommended addition ratio; overuse may cause side effects.
Some additives may interact with each other, test compatibility before mixing multiple masterbatches.
