Final product types

• Fuel line assemblies
• Brake line tubing
• AdBlue/DEF delivery tubes
• Hydraulic clutch lines

2. Industrial Pneumatic and Hydraulic Tubing

Industrial OEMs use this polyamide for extruded tubing in pneumatics and hydraulics, where dimensional accuracy under fluctuating temperature or chemical environments remains necessary.

Typical usage ratio

• Formulated as 100% base polymer, may be filled with up to 20% glass fibre for increased stiffness (ratios adjusted based on required bend radius and working pressure).

Downstream process integration

• Processed via precision tubing extrusion, annealed post-extrusion to relieve residual stresses; occasionally laser-welded to quick-connect fittings within assembly lines.

Final product types

• Pneumatic tube sets
• Hydraulic actuator hoses
• Robotic gripper lines
• Air brake system lines for commercial vehicles

3. Electrical Cable Sheathing for Renewable Energy Plants

Manufacturers of wiring and cabling used in wind turbines and solar farms utilize this PA12 grade as a jacketing material owing to UV resistance, mechanical strength at elevated temperatures, and long-term non-discoloration performance. The material enhances both safety and longevity of power cables exposed to direct sunlight, hostile environments, or chemical splashes.

Industry compliance standards

• UL 1581 (Reference Standard for Electrical Wires, Cables, and Flexible Cords)
• EN 50618 (Power cables for photovoltaic systems)
• IEC 60502-1 (Power Cables with extruded insulation and rated voltages)
• ISO 4892-2 (UV resistance testing procedures)

Typical usage ratio

• Mainly used as an outer layer, 60–100% of the sheath composition; for halogen-free systems, blended up to 40% with flame-retardant masterbatch where local regulation requires additional fire performance.

Downstream process integration

• Melt-processed in tandem extrusion lines, employs crosshead extrusion for sheath application over conductor cores, then passes through continuous vulcanization and cooling stages; colour and marking lines incorporated inline.

Final product types

• PV array cables
• Wind turbine power cables
• Control wiring for substations and converters
• Marine/Offshore fixed-installation power lines

4. Sports Equipment Structural Components

OEMs in the premium sports goods sector employ this PA12 compound to injection mould lightweight, fatigue-resistant frames and hardware. The grey color ensures design consistency for high-end components such as ski bindings or bicycle parts, while the material's long fibre reinforcement delivers stiffness and crack resistance critical in dynamic load applications.

Typical usage ratio

• Utilized at 100% in main frames, or with up to 15% color masterbatch for specific contract shades; glass fibre reinforcement up to 20% for load-bearing components.

Downstream process integration

• Employed in high-pressure injection moulding, demoulded under controlled conditions to prevent warpage, then subjected to machining and surface finishing; assembled with metals or other composites as needed.

Final product types

• Bicycle forks and frame junctions
• Ski binding housings
• Archery bow handle risers
• Sporting gear brackets and fasteners

5. Drinking Water System Fittings

Manufacturers rely on this PA12 grade for potable water connectors and valves due to its compliance with hygienic regulations and resistance to chlorine-induced stress cracking. It ensures long-term safety and mechanical reliability in household and commercial plumbing systems, while preventing taste or odour migration.
