Each type of additive masterbatch has some special properties to improve the end plastic product.

Plast MFI Modifier

These additives play a crucial role in modifying the melt flow index (MFI) of polyolefins, particularly polypropylene (PP)

What is Melt Flow Index (MFI)? The Melt Flow Index (MFI) or Melt Flow Rate (MFR) is a measurement used to assess the flowability or melt viscosity of a polymer.

MFI Modifiers: Purpose and Benefits

Purpose: MFI modifiers are additives designed to alter the MFI of polyolefins, such as PP. They help achieve specific MFI values that are suitable for various applications.
Advantages:
- Stabilization: MFI modifiers, often based on peroxide, stabilize and maintain the desired MFI during processing.
- Increased MFI: By adding MFI modifiers, extrusion-grade polymers (like PP) can be modified to be suitable for injection molding processes

Injection Molding

Purpose: MFI modifiers are particularly useful for injection molding processes.
Explanation: When manufacturing plastic parts through injection molding, it’s essential to use materials with the right MFI. High-flow materials (those with a high MFI) are easier to fill complex mold cavities, ensuring smooth and efficient production.

Melt-Blown Face Mask Production

Purpose: Achieving the desired MFI for melt-blown PP used in face mask production.
Explanation: Melt-blown PP requires specific MFI values to ensure efficient fiber formation during the melt-blown process. MFI modifiers can enhance PP MFI, allowing it to meet the requirements for producing high-quality face masks.
