A recycled additive masterbatch is a specially formulated plastic masterbatch designed to improve the quality, performance, and processability of recycled plastics.
It is made by compounding various functional additives (such as antioxidants, compatibilizers, dispersants, stabilizers,
lubricants, or odor-removing agents) into a carrier resin, usually compatible with recycled polymers like PE, PP, or PET.
Key Functions of Recycled Additive Masterbatch:
- Stabilization – Protects recycled polymers from degradation during reprocessing (heat, shear, UV exposure).
- Compatibilization – Improves compatibility between different types of recycled plastics (e.g., PP/PE blends).
- Odor Removal – Reduces or eliminates unpleasant smells often found in post-consumer recycled plastics.
- Dispersion Improvement – Enhances pigment or filler dispersion in recycled resins.
- Mechanical Property Enhancement – Restores impact strength, elongation, and flexibility lost during recycling.
- Processing Aid – Improves melt flow and extrusion/injection molding performance.
Applications:
- Film blowing (garbage bags, shopping bags, agricultural films)
- Injection molding (household items, automotive parts, packaging)
- Blow molding (containers, bottles)
- Sheet and pipe production using recycled resins
? In short: Recycled additive masterbatch makes recycled plastics more durable, stable, and usable in higher-value applications, helping manufacturers balance cost savings with product performance and sustainability.
