MFI Flow Improver: Boost Melt Flow Without Changing Your Base Resin
A small dose of the right flow improver can solve big processing headaches - faster cycles, lower temperatures, better fill.
What Is an MFI Flow Improver?
An MFI (Melt Flow Index) flow improver is a processing additive that increases the melt flow of a polymer without requiring a switch to a different, more expensive resin grade. Siya Polymer & Speciality Chemicals supplies flow improver additives for PP, PE, HDPE and LLDPE, engineered to enhance processability while maintaining the mechanical properties of the finished part.
Processing Benefits
- Higher melt flow, improving mould filling in complex or thin-wall parts
- Reduced processing temperature, lowering energy consumption
- Shorter cycle times in injection moulding
- Better surface finish and reduced flow-line defects
- Cost savings by avoiding the need for a higher-MFI (often pricier) resin grade
How It Works
Flow improvers work by reducing melt viscosity through controlled chain scission or by modifying polymer chain interactions during processing, allowing the polymer to flow more easily under heat and shear - without permanently compromising the toughness or strength of the moulded part when dosed correctly.
Applications
MFI flow improvers are widely used in injection moulding, extrusion, blow moulding, thin-wall packaging, automotive parts, pipes and industrial moulded components where processing efficiency directly affects production cost.
