ETFE combines mechanical strength with melt-processability, enabling efficient manufacturing of durable, chemically resistant parts.
Supports extrusion, injection molding, and film blowing
Ideal for lightweight yet robust components
Allows shaping into complex forms
Faster cycle times and reduced material waste
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.
Ideal for: Extrusion and molding of products with thick walls
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).
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.

Download GuideETFE (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 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:
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:
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:
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:
Clean handling and proper storage maintain resin purity and ensure consistent melt behavior.
