In today’s plastics industry, the Melt Flow Index (MFI) is one of the most important parameters affecting processing efficiency, production speed, and finished product quality. Manufacturers increasingly rely on MFI Improvers to optimize polymer flow, reduce processing costs, and enhance manufacturing performance.
At MASTERBATCH.VN, we provide technical expertise and high-quality plastic additives to help manufacturers achieve stable processing and consistent product quality.
What Is an MFI Improver?
An MFI Improver (Melt Flow Index Improver) is a plastic processing additive designed to reduce the melt viscosity of thermoplastic polymers. By increasing melt flow, the polymer becomes easier to process during injection molding, extrusion, blow molding, film blowing, and fiber spinning.
When used at the recommended dosage, an MFI improver can:
- Increase production efficiency
- Improve polymer flow consistency
- Reduce processing temperatures and energy consumption
- Shorten molding cycle times
- Produce smoother surface finishes
- Improve dimensional stability
Chemical Composition and Working Principle
Most commercial MFI improvers are based on organic peroxide compounds, including:
- Dicumyl Peroxide (DCP)
- Benzoyl Peroxide (BPO)
When exposed to processing temperatures, these additives decompose and generate free radicals, which selectively break long polymer chains into shorter molecular chains.
As a result, the polymer exhibits:
- Lower melt viscosity
- Higher Melt Flow Index (MFI)
- Improved flowability
- Better processability
This technology is especially effective for recycled PP, recycled PE, ABS, PS, and polypropylene compounds.
Typical Chemical Formula
Dicumyl Peroxide (DCP):
(C₆H₅C(CH₃)₂O)₂
Is an MFI Improver the Same as a Processing Aid?
Not exactly.
Although both products improve plastic processing, they work through different mechanisms.
MFI Improver
- Chemical modification
- Reduces molecular weight
- Increases Melt Flow Index
- Improves resin flow
Processing Aid
- Physical lubrication
- Reduces friction during processing
- Improves mold release
- Enhances surface appearance
In many applications, manufacturers combine both additives to maximize productivity and processing stability.
Applications
MFI Improvers are widely used in:
- Injection molding
- Blow molding
- Film extrusion
- Cast film production
- Fiber spinning
- Raffia tape extrusion
- Woven sack manufacturing
- Recycled plastic processing
- PP and PE recycling
Typical performance improvements include:
- Up to 30% shorter processing cycles
- Significant increase in Melt Flow Index
- Better surface finish
- Improved processing stability
- Lower energy consumption
- Higher production output
