Milliken Viscosity Modifiers
Product Description
Milliken Viscosity Modifiers (MVM) are a range of peroxide masterbatches and concentrates designed for recyclers to increase the melt flow rate of pre-and post-consumer recycled polypropylene (rPP) for the extrusion and injection molding processes. It achieves this by shortening the material’s average molecular chain length, resulting in an easier, more consistent flow while allowing for precise dosing and dust-free handling. MVM-modified recycled PP resins have improved properties for use in a wider range of applications. These rPP resins allow for lower processing temperatures, which can reduce cycle times and boost productivity.
Benefits for Recycled PP
Offered in various peroxide masterbatch concentrations and as free-flowing pellets, this cost-effective product is easy to feed and safe to handle. Recycled PP resins optimized with MVM enable processing at lower temperatures, which can allow converters to reduce cycle times, boost productivity and improve processability.

How do peroxide masterbatches affect molecular weight in recycled PP?
Peroxide masterbatches help control molecular weight by shortening polymer chains during processing. This improves melt flow and supports more consistent extrusion and injection molding performance in recycled polypropylene applications.
Why are viscosity modifiers important for polypropylene packaging materials?
Viscosity modifiers help improve flow consistency and processing efficiency for polypropylene packaging materials such as food containers, lids, and bottle tops. Improved processability can also support better manufacturing productivity and material performance.
Can recycled PP viscosity modifiers support high-temperature processing?
Yes. Recycled PP viscosity modifiers help improve melt flow behavior during high-temperature extrusion and injection molding operations. More controlled flow characteristics can support smoother processing and improved manufacturing consistency.
How do peroxide masterbatches improve polypropylene processability?
Peroxide masterbatches improve polypropylene processability by optimizing polymer chain behavior and viscosity characteristics. This supports easier mold filling, improved blending, and more efficient manufacturing operations using recycled PP materials.
