Improve Processing and Performance in Recycled Polyethylene
Increase recycled content in polyethylene applications while maintaining stable processing, consistent product quality, and long-term performance.
Nexam Chemical provides a complete solution — from melt strength enhancement to stabilization and additive systems — enabling reliable use of recycled PE across film, blow moulding, and pipe applications.

Challenges with recycled polyethylene
Recycled polyethylene (rPE) introduces variability that makes processing more difficult:
- Low melt strength and unstable extrusion
- Sagging parisons in blow moulding
- Film instability and thickness variation
- Contamination and gels
- Inconsistent melt flow and narrow processing windows
These issues often limit how much recycled material can be used in production.
Reactive Recycling™ for polyethylene

Reactive Recycling™ modifies polymer structure directly during processing, improving melt strength and stabilizing recycled material streams.
This allows converters to:
- Increase PCR content
- Improve process stability
- Use lower quality or mixed feedstock
- Maintain consistent production performance
Improved melt strength and process stability
Reactive Recycling™ for rPE enables:
- Increased melt strength → more stable extrusion
- Improved process consistency
- Wider processing window for variable material quality
- Reduced sensitivity to contamination and blend variations
- Use of lower quality feedstock
NexCircle® R401 — high-efficiency melt strength enhancement
NexCircle® R401 is a next-generation reactive additive designed to improve performance of recycled polyethylene at lower dosage.
Key benefits
- Strong melt strength improvement at low addition levels
- Enables higher PCR content with stable processing
- Improves consistency across variable feedstock
- Reduces need for virgin PE blending
- Supports robust industrial processing conditions

Improved melt strength and reduced MFR enable stable processing of recycled polyethylene at higher PCR content.
