High-Performance Crosslinked ETFE Plastic (Model: HD-X930)

Crosslinked ETFE Plastic HD-X930: Superior Toughness, Heat/Chemical Resistance & Insulation. Ideal for Aerospace, Automotive, Nuclear Power Cable & Component Applications.

Crosslinked ETFE (XL-ETFE) Plastic HD-X930 is a modified fluoropolymer material synthesized by incorporating crosslinking agents into ethylene tetrafluoroethylene (ETFE) resin. As a thermoset fluoropolymer, it retains ETFE's inherent lightweight and electrical insulation properties while enhancing mechanical toughness, heat stability, and chemical resistance via crosslinked molecular bonds. Our HD-X930 grade is optimized for extrusion molding, making it a high-performance solution for cable cladding, wire insulation, and components in extreme environments like aerospace, nuclear power, and automotive systems.

What is Crosslinked ETFE Plastic HD-X930?
Crosslinked ETFE Plastic HD-X930 is a specialized thermoset fluoropolymer engineered for demanding industrial applications. Unlike standard ETFE (a thermoplastic), HD-X930 undergoes a crosslinking process-polymer chains are bonded into a 3D network using proprietary crosslinking agents. This structural change is why it outperforms unmodified ETFE: the crosslinked bonds boost mechanical strength (tensile strength >35 MPa) and heat stability (sustains 200°C long-term), while preserving ETFE's low density (1.8) and electrical insulation.
Compared to other fluoropolymers like FEP and PTFE, HD-X930 balances performance and processability: it's more heat-resistant than FEP (which melts ~270°C but has lower long-term thermal stability) and easier to extrude into thin layers than PTFE (which requires specialized processing). Its white pellet form (with a melt flow rate of 18 g/10min) ensures uniform melting during extrusion, critical for consistent cable cladding thickness in high-precision applications.

Each property of HD-X930 is rooted in its crosslinked molecular structure and rigorous formulation:
● Superior Mechanical Toughness: With a tensile strength >35 MPa (ASTM D638) and elongation at break >300%, it resists tearing and impact. The 3D crosslinked network distributes stress evenly across polymer chains, making it 20% more durable than uncrosslinked ETFE-ideal for cables subjected to pulling or vibration in aerospace/automotive systems.
● Enhanced Heat Resistance: It maintains structural integrity at continuous temperatures up to 200°C (melting point 255°C, JIS K 7121). Crosslinked bonds have higher thermal stability than linear ETFE chains, preventing deformation in high-heat environments like engine bays or nuclear power plant equipment.
● Excellent Chemical Resistance: The fluorinated backbone (C-F bonds) and crosslinked structure make it inert to harsh acids, alkalis, and industrial solvents. Unlike PVDF (which degrades in strong bases), HD-X930 remains stable in corrosive settings-critical for oil well and chemical processing components.
● High Electrical Insulation: It has a dielectric coefficient of 2.5 (1MHz, ASTM D150) and volume resistance of 7×10¹¹ MΩ (ASTM D257), ensuring reliable insulation in high-voltage cables (e.g., nuclear power signal lines). Its low dielectric loss (0.005) minimizes signal interference, outperforming many non-fluoropolymer insulators.
● Low Friction & Lightweight: With a low coefficient of friction (similar to PTFE) and density of 1.8 (ASTM D792), it reduces wear in moving components (e.g., automotive brake lines) while cutting weight-key for fuel efficiency in aircraft and vehicles.
● Weather & Moisture Resistance: Crosslinked bonds prevent moisture penetration, and the fluorinated structure resists UV degradation. This makes it suitable for outdoor underground cables (e.g., oil well communication lines) that face long-term exposure to humidity and temperature cycles.
