Final product types

• Pneumatic actuator tubing
• Flexible hydraulic impulse hoses
• Industrial airline assemblies for compressors and valve banks
• Tubing sets for robotic end-effectors

3. Cable Sheathing and Fiber Optic Conduit for Telecommunications

Telecom infrastructure providers use Nylon 12 as a secondary or jacketing layer on buried and aerial cables, leveraging its low permeability to moisture and resistance to environmental stress cracking. This ensures signal integrity over extended networks and protects internal components from degradation due to soil chemicals or UV exposure.

Industry compliance standards

• Telcordia GR-20-CORE (Optical fiber cable standards)
• IEC 60794-1-2 (Fibre optic cable test procedures)

Typical usage ratio

• Outer sheathing applied at 85–100% of envelope thickness, often co-extruded with color tracers. Lower ratios used for thinner functional layers, adjusted based on required abrasion and crush resistance.

Downstream process integration

• Employed as the final or penultimate sheathing stage in tandem extrusion lines, following base PE or PVC insulation. Cooling calibration and in-line marking implemented before cable cutting or drum winding.

Final product types

• Armored fiber optic cable jacketing
• Outdoor and direct burial copper/optic hybrid cables
• Flexible conduits for last-mile connection
• Spiral wrap covers for patch panels and cable harnesses

4. Medical Device Components: Catheter Tubing and Fluid Transfer Lines
