Product Slogan
High-strength ETFE monofilament: corrosion-resistant, UV-stable, and mechanically robust. Outperforms PTFE/FEP in stiffness & impact resistance, ideal for chemical, medical, and fishery applications. Reliable, durable, and engineered for high-performance industrial needs.
Product Overview
Fluoropolymer ETFE (Ethylene Tetrafluoroethylene) high-performance monofilament is a partially fluorinated copolymer extruded into uniform, thin filaments. Unlike fully fluorinated polymers such as PTFE, FEP, and PFA, ETFE combines ethylene's flexibility with tetrafluoroethylene's chemical inertness, resulting in monofilament with exceptional mechanical strength, thermal stability, and environmental resistance. This specialized monofilament is tailored for applications demanding durability, corrosion protection, and dimensional stability under extreme conditions.
Product Details
What is Fluoropolymer ETFE High-Performance Monofilament?
ETFE is a premium engineering fluoropolymer and a partially fluorinated copolymer of ethylene and tetrafluoroethylene (TFE), distinguishing it from fully fluorinated counterparts like PTFE, FEP, and PFA. This unique molecular structure grants ETFE monofilament significantly higher tensile strength, stiffness, and impact resistance than PTFE, FEP, or PFA monofilaments, while maintaining a lower specific weight than most fluoropolymers. Unlike PTFE, which is highly flexible but prone to creep, ETFE monofilament exhibits excellent creep resistance and cold flow resistance, ensuring long-term dimensional stability even under continuous mechanical stress.
Our ETFE high-performance monofilament is produced using Grade HD931, a formulation optimized for filament extrusion. With a density of 1.73–1.85 g/cm³, a melting point of 240–270°C, and a melt index of 8–15 g/10min, this grade delivers consistent extrusion quality and uniform filament diameter. The mechanical properties of HD931 ETFE monofilament are industry-leading: tensile strength exceeds 32 MPa, elongation at break reaches over 330%, and compressive strength tops 45 MPa, with a Shore hardness of more than 60 D. These metrics translate to a monofilament that resists abrasion, tearing, and breakage-critical for applications like chemical filtration and industrial weaving.

Performance Advantages Over Other Fluoropolymers
When compared to PTFE, FEP, and PVDF monofilaments, ETFE high-performance monofilament stands out for its balanced strength and flexibility. PTFE monofilament offers superior non-stick properties but lacks stiffness, making it unsuitable for load-bearing applications. FEP monofilament has better processability but lower tensile strength than ETFE. PVDF monofilament excels in chemical resistance but cannot match ETFE's high-temperature tolerance (PVDF max continuous use temp is 150°C vs. ETFE's 180°C). For industries requiring both mechanical robustness and chemical inertness-such as chemical processing, medical device manufacturing, and aquaculture-ETFE monofilament is the optimal choice.
Key Applications
Chemical Industry: Used in filter bags and mesh screens for corrosive fluid filtration, where its chemical resistance prevents degradation by acids, alkalis, and organic solvents.
Medical Industry: Fabricated into sutures and surgical mesh, as it withstands gamma sterilization and biocompatibility (meets ISO 10993 standards).
Fishery Industry: Made into high-strength fishing nets that resist saltwater corrosion, UV degradation, and marine organism fouling, extending net service life by 3–5 years vs. traditional nylon nets.
Electrical Industry: Utilized as insulation for high-temperature wires, thanks to its excellent dielectric properties (volume resistance >10¹⁷ Ω·cm, dielectric strength 16 MV/m for 0.2mm thickness).

FAQ (Frequently Asked Questions)
Q: How does ETFE monofilament compare to PTFE monofilament in terms of cost and performance?
A: ETFE monofilament is moderately priced (15–20% higher than PTFE) but offers superior tensile strength and creep resistance, reducing long-term replacement costs. It is ideal for applications where PTFE's flexibility is not required but strength is critical.
Q: Can ETFE monofilament be sterilized using autoclaves?
A: Yes. ETFE monofilament can withstand repeated autoclaving at 134°C (273°F) without degradation, making it suitable for medical and laboratory applications.
Q: Is ETFE monofilament recyclable?
A: Yes. Unlike some fully fluorinated polymers, ETFE can be recycled via mechanical extrusion, reducing environmental impact. We offer a take-back program for unused ETFE monofilament scraps.
Q: What is the minimum order quantity (MOQ) for custom ETFE monofilament diameters?
A: The MOQ for custom diameters (ranging from 0.1mm to 5.0mm) is 50kg. For standard diameters (0.5mm, 1.0mm, 2.0mm), we accept orders as low as 10kg.
Q: Does ETFE monofilament resist UV radiation for outdoor use?
A: Absolutely. ETFE monofilament is formulated with UV stabilizers that prevent degradation from prolonged sunlight exposure, making it perfect for outdoor applications like agricultural netting and fishing gear.
