Features Of LAN-XESS Rhenopren MB Processing Aid

  1. Enhances melt flow and processability in sulfur-cured rubber compounds without compromising vulcanization kinetics.

  2. Reduces mixing energy consumption and internal mixer temperature during high-shear compounding.

  3. Improves filler dispersion, particularly for carbon black and silica in EPDM, NR, and SBR formulations.

  4. Maintains excellent scorch safety and does not interfere with accelerator systems or curing profiles.

  5. Non-blooming, non-migrating formulation ensures consistent surface quality and adhesion in multi-layer applications.

Typical Applications Of LAN-XESS Rhenopren MB Processing Aid

  1. Tire treads and sidewalls requiring high dispersion and low-viscosity processing.

  2. Automotive weatherstrips and sealing profiles based on EPDM and thermoplastic elastomers.

  3. Industrial rubber goods including hoses, belts, and vibration dampers.

  4. Technical rubber parts for construction and rail applications demanding dimensional stability and reproducible rheology.

  5. Roller coverings and calendered sheets where uniform thickness and surface finish are critical.
