Aerospace-Grade PEEK Aramid Self-Wrapping Composite Sleeving

Aerospace-Grade PEEK Aramid Self-Wrapping Composite Sleeving

E-FLEX® STW-PEEK is a next-generation side-entry PEEK Aramid Sleeving engineered for the most demanding environments. This product utilizes a sophisticated hybrid weaving process that combines the structural rigidity of high-performance PEEK with the high-tenacity tensile strength of Aramid fibers. Its self-wrapping architecture offers superior “shape memory,” ensuring a high overlap of 65° to 130° to provide 360° gapless protection even during tight harness bending.

As a high-reliability alternative to international benchmarks (such as Roundit 2000 NX HT), our PEEK Aramid Sleeving not only meets global physical performance standards but is also optimized for Anti-Fungal (GJB150.10A) and Low Smoke/Zero Toxicity (BS EN3475) requirements. It is the ideal choice for aircraft engines, rail transit, and precision defense systems.

Physical Properties

The Feature of PEEK Aramid Sleeving

• Superior Thermal & Flame Resistance:

  • The PEEK Aramid Sleeving features  sustains long-term operation at 260℃.

  • Self-extinguishing: Extinguishes within $\le 15$ seconds after flame removal ($60^{\circ}$ tilt test).

  • Low Toxicity & Smoke: Complies with BS EN3475-601/602, strictly limiting hazardous gas emissions (e.g., $HF \le 100\text{ppm}$) and maintaining low optical smoke density ($Ds \le 200$ in flaming mode).

• Elite Mechanical Shielding:

  • Integrated Aramid fibers provide exceptional cut-through and abrasion resistance, successfully passing 1,000 bending cycles ($10\text{N}$ load) and 100+ needle-scraping cycles without rupture.

  • The PEEK Aramid Sleeving maintains high structural integrity even after high-intensity solar radiation ($1127 \pm 47\text{W/m}^2$ for 40 hours).

• Chemical Inertness & Environmental Resilience:

  • Immune to Skydrol (hydraulic fluid), jet fuel (JP-8), and de-icing fluids at $70 \pm 3^{\circ}\text{C}$.

  • Anti-Fungal Grade $\le 1$: Complies with GJB150.10A-2009, ensuring zero biological growth in humid or maritime environments.

• Simplified Installation & Maintenance:

  • The side-opening structure of the PEEK Aramid Sleeving allows for installation on existing harnesses, while a distinct $9\text{ mm}$ white tracer line assists in precise alignment.

Product Applications

• Aerospace: Engine nacelles, wing pylon harnesses, flight data recorder (black box) lines, and satellite attitude control systems.

• Defense Equipment: Armored vehicle turret rotation systems, UAV (Unmanned Aerial Vehicle) control buses, and precision-guided weapon electronics.

• Rail Transit: High-voltage connectors under high-speed trains, locomotive traction systems, and inter-car jumpers.

• Energy Industry: High-temperature sensors for oil/gas drilling and high-temp power transmission grids.

System Capabilities & Customization

• Manufacturing Excellence: We operate as a Standard-Excellence manufacturer of PEEK Aramid Sleeving, with processes following ISO quality systems. We provide compatibility with RoHS, Halogen-Free, and military/civil aviation standards.

• Customization Solutions:

  • Dimensional Customization: Standard sizes for PEEK Aramid Sleeving range from 5 mmto 40 mm, with support for custom profiles.

  • Material Tuning: The weaving ratio of Aramid to PEEK can be adjusted based on specific application needs (e.g., extreme friction environments).

  • Industry Adaptation: Supports specific color identification schemes (Standard: Army Green with White Tracer) and precision cutting.
