NexCircle® R401: high-efficiency melt strength enhancer for rPE

Stable rPE processing at higher PCR content

NexCircle® R401 is a next-generation reactive additive designed to improve recycled polyethylene performance at low addition levels. It helps increase melt strength and create more stable processing conditions with variable feedstock quality.

Nexam Chemical positions R401 as a high-efficiency solution that supports higher PCR use, helps reduce the need for blending with virgin PE, and suits industrial process conditions.

Frequently asked questions

Which brand does R401 belong to?
Nexam Chemical presents the product under the NexCircle® brand. The correct and only spelling is NexCircle® R401.
Which polymer is R401 for?
It is for recycled polyethylene (rPE).
Does it reduce virgin PE use?
Nexam states that it supports the goal of higher PCR and less virgin PE blending; the actual ratio depends on feedstock and product specification.
How do I choose between R401 and R305?
R401 focuses on next-generation high efficiency at low addition level; R305 is the proven rPE solution. Selection should be made through a technical trial.

The technical statements on this page are based on the manufacturer’s current public product information. Dosage, temperature and performance targets are defined per line through technical trial.
