Final product types

• Air brake lines (truck and trailer)
• Pneumatic actuator tubing for automation
• Pilot lines for process instrumentation
• Hydraulic hose linings in mobile machinery

3. Electrical & Electronics: Cable Sheathing and Connectors

Major wire and cable manufacturers select this modified PA12 for specialty sheathing applications, where thermal stability, abrasion resistance, and UV-hardened color retention must meet the strictest product life-cycle requirements. It sees frequent use in shielding and jacketing of fiber optic and communication cables, especially for outdoor or automotive wiring harnesses exposed to demanding operating environments.

Industry compliance standards

• UL 1581 (Electrical Wires, Cables, and Flexible Cords – Reference Standard)
• IEC 60811 (Tests for Non-metallic Sheaths and Insulations)

Downstream process integration

• PVC or PE-insulated cables receive a final high-performance PA12 layer either via co-extrusion or jacketing extrusion step, with in-line laser marking and automated spool-up.

Final product types

• Fiber optic cable sheathing and loose tubes
• Multi-core signal wiring harness jackets
• Splice protection sleeves for outdoor telecom
• Screw and plug-style electrical connectors

4. Sports & Leisure: High-performance Bicycle and Bowden Cables

Bicycle component OEMs and recreational equipment assemblers rely on PA12 for outer casing in mechanical cable systems due to its balance of flexibility, friction control, and durable black surface. It consistently outperforms alternative polyamides in retaining smooth draw characteristics after protracted outdoor cycling use or frequent articulation cycles in sports gear assemblies.

Industry compliance standards

• ISO 4210-2 and ISO 4210-5 (Cycles – Safety requirements for bicycles and frame components)
