Features Of LAN-XESS Rhenosin W90B Processing Aid

  1. Enhances melt flow and processability in high-viscosity thermoplastics without compromising mechanical performance.

  2. Reduces extrusion torque and energy consumption during compounding and extrusion processes.

  3. Improves dispersion of fillers and pigments in engineering polymer formulations.

  4. Thermally stable up to 300 °C, supporting high-temperature processing of polyamides and PBT.

  5. Non-migrating and non-blooming—ensures long-term surface integrity and compatibility with downstream finishing.

Typical Applications Of LAN-XESS Rhenosin W90B Processing Aid

  1. Engineering plastics compounding (e.g., PA6, PA66, PBT).

  2. High-performance cable sheathing and insulation compounds.

  3. Automotive interior and under-hood components requiring consistent melt homogeneity.

  4. Recycled polymer blends where rheological control and contamination tolerance are critical.

  5. Thin-wall injection molding of precision technical parts.
