Overview of Extrusion-Grade MFI 12 PP CF Composite
MFI 12 PP (Melt Flow Index 12 g/10min Polypropylene) Carbon Fiber (CF) Reinforced Composite is a high-performance thermoplastic material specifically designed for extrusion processes. This composite utilizes MFI 12 PP as the matrix, reinforced with chopped carbon fibers (typically 10%~30% loading), combining the processing advantages of polypropylene with the mechanical reinforcement of carbon fibers. It is ideal for continuous extrusion applications such as pipes, profiles, and sheets.
Why MFI 12 PP CF is Suitable for Extrusion Applications
-
Optimal Melt Flow for Processing
-
The MFI 12 PP base resin (12 g/10min at 230°C/2.16kg) exhibits moderate-to-high flowability, ensuring smooth plastication in extruder screws while preventing fiber agglomeration due to excessive flow. Experimental data shows that this MFI range achieves the best balance between extrusion pressure (typically 15~25 MPa) and output efficiency.

-
Enhanced Mechanical & Thermal Performance
-
With 20% carbon fiber reinforcement, MFI 12 PP CF demonstrates a tensile strength of 80~100 MPa (vs. ~30 MPa for neat PP) and a heat deflection temperature (HDT) increase of over 40°C (reaching 120°C). Fiber orientation can be further optimized through die design, improving longitudinal mechanical properties by 15%~20%.
-
-
Process Compatibility
-
Recommended barrel temperature settings (180~220°C from feed zone to die) align perfectly with the melting characteristics of MFI 12 PP, preventing carbon fiber degradation (resin degradation risks above 240°C). A screw L/D ratio ≥25:1 ensures uniform fiber dispersion and minimizes surface defects.
-
MFI 12 PP CF is an ideal choice for extrusion molding (e.g., automotive spoilers, industrial corrosion-resistant pipes) due to its balanced flowability, superior reinforcement, and stable processing window. Data confirms its exceptional synergy between performance and process parameters, outperforming conventional filled PP grades in precision continuous production.
Surface Resistivity Comparison
Conductors < 10⁵ Ω/sq. Antistatic Materials 10⁵ ~ 10¹² Ω/sq. Insulators > 10¹² Ω/sq. Static-Dissipative 10⁶ ~ 10¹¹ Ω/sq. *Key Influencing Factors Humidity: Increased moisture can reduce resistivity (e.g., in polymers). Temperature: Affects carrier mobility (↑ heat may lower semiconductor resistivity). Surface Contamination: Dust/oils alter readings significantly. Additives: Carbon black, metallic fillers can lower resistivity. *Applications Electronics: Antistatic materials (10⁶–10⁹ Ω/sq) prevent electrostatic discharge (ESD). Aerospace: Composites must control resistivity to avoid charge buildup. Medical Devices: Insulating materials (>10¹² Ω/sq) ensure patient safety. *Examples Polypropylene (PP): ~10¹⁶ Ω/sq (excellent insulator). Carbon Fiber Composites: 10³–10⁶ Ω/sq (static dissipation). ESD Flooring: 10⁶–10⁹ Ω/sq.
Get to Know Carbon Fibers
The table presents key performance data of carbon fiber grades. T300, with a tensile strength of 3530 MPa and a tensile modulus of 230 GPa, has a relatively low tensile elongation at break of 1.5% and a body density of 1.76 g/cm³. As the grade increases, for example, T700S shows an enhanced tensile strength of 4900 MPa compared to T300, while maintaining the same tensile modulus but with a higher elongation at break of 2.1%. T800S and T1000G both have a tensile modulus of 294 GPa, and their tensile strengths are 5880 MPa and 6370 MPa respectively. T1100G stands out with the highest tensile strength of 7000 MPa and a tensile modulus of 324 GPa. Generally, with the increase in product grade, the tensile strength and modulus tend to rise, while the density remains relatively stable around 1.8 g/cm³.
