Features Of LAN-XESS Rhenogran P91-40/NBR Processing Aid

  1. Enhances processability of NBR compounds by reducing viscosity and improving filler dispersion.

  2. Minimizes die swell and improves extrudate dimensional stability during rubber processing.

  3. Compatible with standard NBR formulations, including high-acrylonitrile grades.

  4. Reduces energy consumption and mechanical stress on mixing and extrusion equipment.

  5. Non-dusting granular form ensures safe handling and consistent dosing in automated systems.

Typical Applications Of LAN-XESS Rhenogran P91-40/NBR Processing Aid

  1. Automotive sealing profiles (e.g., window channels, trunk seals).

  2. Industrial hoses and hydraulic tubing requiring oil resistance.

  3. Oil and fuel-resistant gaskets for engine and transmission components.

  4. Roller coverings and conveyor belts operating in demanding chemical environments.

  5. Injection-molded NBR parts requiring high surface quality and tight tolerances.
