Melt Flow Index Modifier

A process-control additive with different formulation roles in PP and PE: it can raise PP melt flow or reduce PE melt flow while improving fluidity, gloss and selected weld-line cracking behavior in large molded parts.

Melt Flow Index Regulators

MFI regulation grade for processing flow adjustment.

Applicable Materials

  • PP
  • PE

Typical Applications

  • PP compounding and injection molding flow improvement
  • HDPE extrusion pipes, boards and profiles
  • Projects requiring melt flow adjustment and processing stability

Key Benefits

  • Can increase PP flow or reduce PE flow depending on formulation direction
  • Helps improve fluidity, gloss and selected weld-line issues
  • Useful for production process troubleshooting and formulation tuning

Selection Notes

  • Confirm polymer type, current MFI, target MFI and processing temperature before recommendation; the catalog trial range is 2-4%.
  • Suitable for compounding, injection molding, extrusion, blow molding, film or sheet trials depending on the resin system.
  • Share base resin, target performance, part thickness and process route before final grade selection.
  • Use TDS/SDS and small-batch testing to confirm dosage, appearance and final performance before mass production.
Performance and testing notice

Confirm performance in the actual formulation and process

Actual results may vary with resin grade, material condition, formulation, dosage, part thickness, material and mold temperature, equipment, processing parameters, humidity, storage and test environment. Published values and application descriptions are selection references, not unconditional guarantees. Review the current TDS / SDS and complete application-specific testing before production approval.
