Filler masterbatch compounding

Filler masterbatch pellets

Application challenge

  • Highly loaded concentrates with good pellet integrity are preferred by compounders
  • Extrusion of compounds made from highly filled concentrates requires that:
    - Good dispersion be accomplished easily
    - Cross-linked polymer gels be avoided

Material solution and key benefits

Vistamaxx™ 6202 propylene-based elastomer replacing 5-15% of existing polyethylene (PE) or polypropylene (PP) carrier in filler masterbatches delivers:

  • Better dispersion and pelletization for improved lot-to-lot quality consistency
  • Higher filler loading to enable higher let-down ratios, resulting in lower fabrication cost
  • Lower processing temperatures, potentially reducing gels and oxidized materials
  • Better tensile strength and higher yarn stretch ratio
  • Improved impact and tear properties
