Control flow behaviour, ensure consistent processing, and maintain product performance when using recycled PP and PE in injection moulding.

Recycled PP and PE often introduce variability that affects both processing and final part quality:

• Inconsistent melt flow (MFR variation)
• Poor filling of complex mould geometries
• Surface defects and flow marks
• Variation between batches
• Reduced process stability and repeatability

This limits the use of recycled materials in demanding injection moulding applications.

Reactive Recycling™ enables controlled modification of polymer structure during processing, allowing converters to adapt recycled materials to required processing conditions.

This makes it possible to achieve stable and repeatable injection moulding performance using recycled polyolefins.

Key effects

• Enables controlled adjustment of melt flow (MFR)
• Improves mould filling in complex geometries
• Reduces variability between batches
• Improves surface quality and consistency
• Stabilizes processing conditions

NEXAMITE® R202 is a reactive masterbatch designed to increase melt flow (MFR) in recycled polypropylene, enabling improved processability in injection moulding.

It allows converters to adapt recycled materials to the required flow characteristics — without relying on virgin polymers.

Available in different activity levels:

• R202-1 (~5% peroxide)
• R202-2 (~10% peroxide)
• R202-4 (~20% peroxide)

Key benefits

• Efficient increase of MFR and flow in recycled PP
• Improved filling of complex moulds
• Enables shorter cycle times and improved flow length
• Reduces need for virgin material to adjust processing
• Controlled and predictable adjustment of material properties
• Improved surface finish and reduced flow marks
• Better replication of fine details in moulds
• More stable cycle times and reduced rejects
• Wider processing window for variable recycled feedstock

Maintaining consistent colour and appearance is often one of the biggest challenges when using recycled polyolefins.

Variations in feedstock, such as base colour, degradation level, and contamination, can lead to visible differences between parts and batches.

ReColour Plus™ is a tailored masterbatch concept developed for recycled polyolefins that addresses these challenges by enabling consistent colour and appearance in recycled plastics, even with variable feedstock.

It combines colour formulation, material upgrading, and additive packages to ensure stable processing and repeatable results.

ReColour Plus™

• Ensures consistent colour despite variable feedstock
• Reduces visual defects and batch-to-batch variation
• Enables use of recycled polyolefins in demanding applications
