Understanding ETFE 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).

Discover How ETFE Streamlines High-Performance Manufacturing

ETFE (Ethylene Tetrafluoroethylene) is a melt-processable fluoropolymer that delivers mechanical durability, chemical resistance, and outdoor stability – while enabling efficient thermal processing for complex part production.

Unlike PTFE, ETFE can be extruded, injection molded, or blow molded into films, tubes, sheets, and components with precise dimensional control. Its high strength-to-weight ratio and impact resistance make it ideal for applications requiring durability under stress, such as aerospace wiring, fluid handling, and architectural membranes.

ETFE’s processability reduces cycle times, minimizes scrap, and supports cost-effective production of high-performance parts. With UV resistance and long-term outdoor stability, ETFE is also the material of choice for solar panel encapsulation, insulated wires, and protective coatings.

Choosing ETFE means achieving strong, lightweight, and reliable components while improving production efficiency across demanding industrial applications.

XIFLON ETFE RESIN FAQ

What is ETFE resin and how is it different from PTFE and FEP?

ETFE (Ethylene Tetrafluoroethylene) is a partially fluorinated thermoplastic with excellent mechanical strength, UV resistance, and chemical stability. It is melt-processable like FEP and PFA, but differs in structure and performance:

  • ETFE vs. PTFE: PTFE is non-melt-processable and requires sintering after molding or RAM extrusion. ETFE can be extruded or molded using standard thermoplastic techniques and offers higher mechanical strength and impact resistance, but lower chemical and thermal resistance.
  • ETFE vs. FEP: FEP has better chemical resistance and operates at higher continuous temperatures (up to ~200 °C), while ETFE operates up to ~150 °C. However, ETFE excels in toughness, abrasion resistance, and UV durability.

ETFE is often chosen for outdoor or structural applications where mechanical integrity and weatherability are critical.

ETFE is melt-processable and compatible with standard thermoplastic shaping techniques:

  • Extrusion: For films, wire insulation, and tubing, with melt temperatures ranging from 260–300 °C.
  • Injection molding: For durable, impact-resistant parts such as fittings or components.
  • Blow molding: Used for pressure-resistant containers or membrane structures.
  • Thermoforming: Thin ETFE films and sheets can be shaped into domes or panels at elevated temperatures.
  • Rotational molding and coating: Used for linings or large hollow parts requiring chemical and abrasion protection.

Its low melt viscosity and high strength make ETFE suitable for complex and durable products.

ETFE is widely used across construction, wire & cable, and specialty industrial sectors:

  • Architectural: Lightweight membrane structures, roofing, and facades (e.g., stadiums and skylights) thanks to its transparency, UV resistance, and weatherability.
  • Wire & cable: Jacketing and insulation for aerospace, automotive, and industrial equipment where high strength and flame resistance are required.
  • Solar and greenhouse films: High light transmission and durability under prolonged UV exposure.
  • Chemical processing: Tubing, valves, and linings resistant to moderate corrosive agents.
  • Medical: Sterilizable and abrasion-resistant films and tubing.

Its toughness, transparency, and resistance to aging make it ideal for long-term demanding environments.

ETFE is recognized for its balance of mechanical, chemical, and environmental performance:

  • Melt Flow Rate (MFR): 2–36 g/10 min depending on grade; higher MFR is preferred for high-speed extrusion.
  • Tensile strength: ~30–40 MPa, supporting mechanical and dynamic loading.
  • Elongation at break: >280%, ensuring flexibility and impact resistance.
  • Melting point: ~260–270 °C, suitable for thermoforming and high-temperature uses.
  • Density: ~1.7 g/cm³, lighter than PTFE, contributing to lightweight structures.

Selecting the proper ETFE grade is essential for processing consistency and mechanical performance.

Although ETFE is chemically stable and non-hygroscopic, proper handling ensures optimal processing results:

  • Storage temperature: Keep between 10–30 °C in a clean, dry, and ventilated environment.
  • Packaging: Delivered in sealed bags or drums to prevent contamination. Do not open until processing.
  • Drying: Not needed unless exposed to moisture.
  • Processing: Always observe safety guidelines specific to fluoropolymer materials.

Clean handling and proper storage maintain resin purity and ensure consistent melt behavior.
