XLETFE Radiation Cross-Linking Architecture
Molecular Reinforcement Beyond Traditional Thermoplastics
Radiation Cross-Linkable
Electron-Beam (E-Beam) Bridging Technology
Everflon+™ ETFE X4010 is optimized for high-efficiency electron-beam irradiation. Following wire extrusion or molding, controlled exposure induces robust three-dimensional polymer network cross-linking, completely eliminating high-temperature flow deformation typical of standard thermoplastics.
Superior Solder Resistance
Eliminates Hot Iron Meltback
During high-density electronic harness assembly and manual soldering, the cross-linked XLETFE insulation layer exhibits exceptional immunity to thermal melting and shrinkage, securing terminal integrity.
Mechanical Abrasion Defense
Exceptional Cut-Through & Scratch Resistance
The cross-linked molecular matrix provides high surface hardness and cut-through durability, easily withstanding tight automotive routing friction and harsh aerospace dynamic pulling forces.
Thin-Wall Lightweight Design
Enhanced Strength Enables Extreme Wire Harness Weight Savings
Because cross-linking multiplies mechanical resilience, wire designs can incorporate thinner insulation walls while maintaining superior dielectric performance, significantly reducing overall harness weight for aerospace and EV efficiency.

Extrusion & Irradiation Guidelines
Wire Extrusion, E-Beam Parameters & Target Applications
01. High-Speed Wire Insulation Extrusion
Thin-Wall Coating & Stable Parameters
Optimized for high-speed tubular or pressure extrusion lines. Recommended melt temperatures range from 320°C to 360°C. Featuring an MFI of 8–15, it balances melt flow and draw-down tension for uniform concentricity on fine-gauge conductors.
02. Electron-Beam (E-Beam) Irradiation
Precise Dosimetry & 3D Network Building
Extruded wires are routed through an electron accelerator for cross-linking. Optimized dosage levels lock in superior thermal endurance, cut-through protection, and high-temperature solder melt resistance.
03. Conductor & Equipment Compatibility
Tinned / Silver-Plated Copper
Seamlessly compatible with tinned copper, silver-plated copper, and high-strength alloy conductors. Extruder fluid-contact parts should utilize corrosion-resistant alloy steels for continuous production runs.
Target Applications for Extreme Wire & Cable Markets
Aerospace & Defense High-Temp Wire Harnesses Lightweight, thin-wall aircraft hook-up wires complying with rigorous aerospace specifications, withstanding severe mechanical vibration and extreme thermal ranges.
Automotive Engine Bay & Sensor Wiring Thin-wall signal and power cables for EV and ICE engine compartments demanding solder-iron resistance and long-term thermal aging protection.
High-End Industrial & Server Internal Interconnects High-density electronic internal wiring that avoids insulation melt deformation during automated mass soldering operations.
Logistics & Safety Protocols
Packaging, Storage & Safe Handling Guidelines
