Understanding PFA Melt Flow Rates

Select from our range of grades with varying Melt Flow Rates (MFR), tailored to specific processing needs.

MFR (g/10 min) is inversely related to melt viscosity and determines the polymer’s flow behavior during melt processing such as extrusion or molding.

Lower MFR

  • Higher viscosity
  • Increased melt strength
  • Suitable for processes requiring dimensional stability

Ideal for: Extrusion and molding of products with thick walls

Higher MFR

  • Lower viscosity
  • Easier flow
  • Ideal for intricate shapes and thin-wall applications

Ideal for: injection molding, fast-processing techniques

Note: MFR is not a direct measurement of viscosity but a standard flow index obtained under specific conditions (ISO 1133 or ASTM D1238).

Learn how Melt-Processable Fluoropolymers Like PFA Improve Production

PFA (Perfluoroalkoxy) stands out among fluoropolymers by combining exceptional chemical resistance with melt-processability – which is a rare combination that unlocks significant manufacturing advantages.

Unlike PTFE, PFA can be thermally processed using extrusion, compression molding, injection molding, and blow molding techniques. Finished parts can undergo post-processing such as welding, enabling the production of complex components with tight tolerances, smooth surface finishes, and consistent dimensional control. This simplifies manufacturing workflows and leads to reduced material waste.

PFA’s weldability supports the construction of seamless fluid paths in chemical processing and semiconductor equipment. Its excellent thermal stability and high dielectric strength make it the material of choice for a variety of cable constructions, such as coaxial cables, and data transmission lines, as well as important parts used in cleanroom, aerospace, and industrial automation environments.

Choosing PFA means optimizing throughput, reducing processing complexity, and meeting the highest standards in chemical, electronic, and cable applications.

XIFLON PFA RESIN FAQ

PFA (Perfluoroalkoxy) is a fully fluorinated thermoplastic resin with excellent chemical resistance, high-temperature stability, and electrical insulation. It is part of the fluoropolymer family, like PTFE (Polytetrafluoroethylene) and FEP (Fluorinated Ethylene Propylene), but differs in key aspects:
  • PFA vs. PTFE: PTFE is not melt-processable; it must be compression molded or RAM extruded and further sintered. Unlike this, PFA can be directly extruded or molded using standard thermoplastic processes. Both resist temperatures up to 260 °C and have similar chemical resistance.
  • PFA vs. FEP: FEP is also melt-processable but has a lower continuous use temperature (~200 °C) and slightly lower mechanical strength. PFA is better suited for harsh environments involving heat, chemicals, or high purity.
In summary, PFA combines the chemical resistance of PTFE with the processability of FEP, making it highly versatile for demanding applications.
PFA is melt-processable and can be shaped using standard thermoplastic techniques:
  • Extrusion: For tubing, films, and wire insulation. It requires melt temperatures around 360–400 °C.
  • Injection molding: For complex parts like valve bodies and connectors. Grades with higher MFR are more compatible with this type of processing.
  • Blow molding: For containers and bottles where high-purity chemical resistance is needed.
  • Compression molding: For thick or lined parts requiring mechanical strength and chemical protection.
  • Film extrusion and thermoforming: Thin PFA films are cast or extruded, then formed into diaphragms or barriers.
PFA’s high melt viscosity and thermal stability require precise temperature and shear control during processing.
PFA is used in sectors requiring extreme durability and purity:
  • Wire & cable: High-performance insulation for aerospace, automotive, and telecommunications due to excellent dielectric strength and thermal resistance.
  • Semiconductor: Tubing, fittings, and tank linings in wet process stations. PFA high chemical resistance make it ideal for pure media handling.
  • Chemical processing: Linings for pipes, pumps, and reactors handling aggressive media like HCl, HF, or oxidizers.
  • Medical/pharma: Tubing, bags, and fluid contact parts where biocompatibility, sterilizability, and cleanliness are required.
  • Food & beverage: Non-stick coatings and tubing compliant with FDA and EU regulations.
Its resistance to permeation, non-stick surface, and thermal integrity make PFA suitable for harsh or regulated environments.
Several performance indicators are critical when choosing a PFA resin:
  • Melt Flow Rate (MFR): Indicates processability. Low MFR is used for molding; high MFR (e.g., 20–36 g/10 min) for high-speed extrusion and injection molding.
  • Tensile strength: Typically > 24 MPa; higher values support mechanical loads.
  • Elongation at break: > 300%; indicates flexibility and toughness.
  • Melting point: ~305 °C; important for defining the safe processing window.
  • Density: ~2.15 g/cm³; reflects high crystallinity and chemical resistance.
Always make sure to select the most suitable MFR and technical specification to ensure consistent results in production.
While PFA is chemically inert and non-hygroscopic, proper storage and handling are essential to maintain quality:
  • Storage temperature: Keep between 10–30 °C in a dry, clean, well-ventilated area, away from direct sunlight and heat sources area.
  • Packaging: Supplied in high-density polyethylene bags, placed in plastic drums. Do not open until ready for use. Repack any unused material after use to avoid contamination.
  • Drying: Not usually required, but if exposed to moisture or humidity, drying at 120–130 °C for 2–4 hours can improve surface finish.
  • Shelf life: Typically, 1–2 years if sealed.
Correct handling ensures consistent extrusion or molding behavior, critical for high-purity or precision parts.
