Typical usage ratio

• 100% as base polymer for extrusion, optionally co-extruded with tie layers or barrier materials in multilayer constructions; adjustments possible based on target pressure resistance and flexibility

Downstream process integration

• Material enters as dried pellets in high-speed single-screw or twin-screw extruders for seamless or multilayer-tube extrusion; subsequent laser marking and welding operations performed before full assembly

Final product types

• High-pressure fuel supply lines
• Brake lines and hydraulic conduit tubing
• Pneumatic control tubing for air brake systems

2. Pneumatic and Hydraulics Industrial Tubing

Industrial pneumatic and hydraulic equipment manufacturers specify this PA12 grade for control tubing and piping, where dimensional precision and environmental resistance guarantee smooth installation and safe operation under cyclic loading. Its low extractable content and certified compliance allow use in clean-room and compressor environments, particularly in applications exposed to fluctuating humidity and pressure swings. Glass fiber reinforcement offers reliable crush resistance and retained flexibility during long-term service.

Downstream process integration

• Direct feeding into extrusion lines for single or multi-channel tubing; tubes cut to precise lengths and undergo vacuum calibration, surface smoothing, and offline pressure testing before final packaging

Final product types

• Pneumatic actuator hoses for robotics
• Hydraulic pilot lines
• Process and utility gas transfer tubes

3. Electrical and Electronics Cable Sheathing

Producers of specialty data, control, and sensor cables integrate this polyamide 12 compound for robust sheath layers that shield conductors from oil, grease, heat, and mechanical damage, especially in automation, rail, and energy management systems.

Final product types

• Industrial Ethernet and sensor cables
• Power control cable sheathing
• Rail vehicle wiring

4. Water Treatment System Fittings and Manifolds

OEMs in the water filtration and water dispensing sectors use our PA12 material for molded fittings, multi-port manifolds, and housing connectors exposed to fluctuating chlorination, mineral content, and elevated temperatures. The stabilized resin meets stringent potability and extractable residue tests, making it reliable for contact with both drinking water and process water in controlled industrial or office environments. The focused use of glass reinforcement limits creep deformation under continuous hydraulic stress.
