MAXILOOP® Compatibilizer Masterbatch – Recycled Polymers

Compatibilizer Masterbatch for Recycled Polymers is a high-performance additive solution designed to improve compatibility, dispersion, and mechanical performance in recycled plastic materials. By enhancing the interfacial bonding between different polymers or between polymer and fillers, compatibilizer masterbatch enables higher-quality recycling and more consistent end-product performance.

This masterbatch plays a critical role in mechanical recycling streams where mixed polymers, multilayer waste, or contaminated recyclates are used. Compatibilizer masterbatch helps transform recycled polymers into reliable, high-value raw materials suitable for demanding applications.

What Is MAXILOOP® Compatibilizer Masterbatch?

Compatibilizer Masterbatch contains functionalized polymers (such as grafted polyolefins) that act as molecular bridges between otherwise incompatible polymer phases. During processing, these compatibilizers improve adhesion, stabilize morphology, and enhance dispersion within recycled polymer blends.

As a result, recycled plastics show improved mechanical strength, impact resistance, surface quality, and processing stability. Compatibilizer masterbatch allows manufacturers to use higher percentages of recycled content without sacrificing product performance.

Formulations can be tailored to specific recycling streams, polymer combinations, and end-use requirements.

Applications of Compatibilizer Masterbatch for Recycled Polymers

  • Compatibilizer Masterbatch for Packaging

Improves mechanical properties and processability of recycled polyolefin packaging, including films, rigid packaging, and closures, enabling higher recycled content while maintaining quality.

  • Compatibilizer Masterbatch for Automotive Applications

Enhances strength and impact resistance of recycled plastic compounds used in interior trims, under-the-hood components, and technical parts.

  • Compatibilizer Masterbatch for Building & Construction

Used in recycled plastic profiles, pipes, sheets, and composite materials to improve durability, stiffness, and long-term performance.

  • Compatibilizer Masterbatch for Consumer & Industrial Products

Supports consistent quality in recycled household goods, containers, furniture components, and industrial products made from mixed polymer streams.

Technical Properties of Compatibilizer Masterbatch

Key technical characteristics include:

  • Improved interfacial adhesion between incompatible polymers
  • Enhanced dispersion of fillers and reinforcements
  • Increased impact strength and tensile properties
  • Reduced phase separation in recycled blends
  • Improved melt stability and processability
  • Consistent mechanical performance with higher recycled content

Compatible Polymers & Recycling Streams

Compatibilizer Masterbatch can be formulated for a wide range of recycled polymers and blends, including:

  • Recycled Polypropylene (rPP)
  • Recycled Polyethylene (rPE – HDPE, LDPE, LLDPE)
  • PP/PE mixed waste streams
  • Polymer blends with mineral fillers or fibres
  • Post-consumer and post-industrial recyclates

Custom compatibilizer solutions are available to match specific waste streams, contamination levels, and processing methods.

Compatibility & Performance Options

Compatibilizer masterbatch is available in multiple functional configurations to support different recycling challenges.

  • Polyolefin Compatibilizers: Optimized for PP/PE blends, improving morphology and mechanical consistency in mixed plastic waste.
  • Filler & Fibre Compatibilizers: Enhance bonding between polymers and fillers such as calcium carbonate, talc, glass fibre, or natural fibres.
  • High-Recycled-Content Solutions: Designed to stabilize formulations with high recycled polymer ratios while maintaining strength, impact resistance, and surface quality.
