Features Of Sanyo Chemical UMEX Acid Modified Low-Molecular-Weight Polypropylene Dispersant

  1. Enhanced pigment and filler dispersion stability in non-polar polymer matrices.

  2. Improved melt flow and processing efficiency during compounding and extrusion.

  3. Strong anchoring capability via carboxylic acid groups for robust interfacial adhesion.

  4. Low molecular weight ensures rapid migration to particle surfaces without compromising matrix integrity.

  5. Thermally stable up to 280 °C, suitable for high-temperature polyolefin processing.

Typical Applications Of Sanyo Chemical UMEX Acid Modified Low-Molecular-Weight Polypropylene Dispersant

  1. Masterbatch production for color and additive concentrates in PP and PE systems.

  2. Functional filler dispersion (e.g., talc, CaCO₃, glass fiber) in automotive interior compounds.

  3. Carbon black dispersion in conductive polypropylene composites.

  4. Mineral-filled packaging films requiring high clarity and uniform dispersion.

  5. Recycled polyolefin upgrading to improve consistency and mechanical performance.
