Typical usage ratio

• 100% base polymer; some formulations blend 1-8% impact modifiers or process aids depending on flexibility or chemical resistance requirements

Downstream process integration

• Pellets are dried and directly injection molded or extruded for fuel tube, quick connectors, or check valves; grey masterbatch ensures visible part coding without post-molding coloration

Final product types

• Fuel lines (mono- and multilayer)
• Quick connectors
• Purge valves
• Vapor separators

2. Pneumatic and Hydraulic Tubing for Industrial Automation

Precision pipe and flexible tubing producers rely on Grilamid® L 20 G grey 9280 PA12 for its pressure-bearing capability, low moisture uptake, and consistent surface finish.

Typical usage ratio

• Typically 100% as main polymer; anti-static or UV stabilizer masterbatch up to 3% if required for specialty installations

Downstream process integration

• The granules are compounded or directly extruded through multi-layer pipe extrusion dies to form seamless tubing, then laser-marked with batch codes and cut to customer-specified lengths

Final product types

• Pneumatic hoses for robotics
• Hydraulic low-pressure tubing
• Cable protection conduits
• Signal line covers

3. Medical Device Housing and Connectors (Non-Implant)

Medical device OEMs use this formulation for housings, luer or threaded connectors, and instrument covers requiring reliable sterilization tolerance, mechanical strength, and stable coloring.

Typical usage ratio

• 95–100% pure polyamide; pigment masterbatch up to 5% for medical-grade grey

Downstream process integration

• Material supplied as pellets for micro-injection molding or precision extrusion; finished parts undergo gamma, ETO, or steam sterilization as final assembly step

Final product types

• Luer fittings and connectors
• Respiratory device housings
• Diagnostic sensor enclosures
• Electromedical device covers

4. Electrical & Electronics: Industrial Sensor and Connector Bodies

Electronics manufacturers select the grade for robust sensor heads, plug bodies, and cable overmolding that require resistance to workplace oils, soldering fluxes, and mechanical impact. The consistent electrical insulation and inherent dimensional control support high precision assembly lines across factory automation, process control, and building infrastructure equipment, especially for signal cables using color ID protocols.

Industry compliance standards

• IEC 60695-2-11 (Glow-Wire Flammability Test)
• UL 94 HB (Horizontal Burning test, for non-primary insulation)

Final product types

• Industrial connector housings
• Proximity and inductive sensor bodies
• Cable terminations for automation
• Junction box covers

5. Sports Equipment: High-End Bicycle Brake and Gear Lines

Bicycle component OEMs and after-market suppliers process this formulation for brake and gear cable housings in high-performance and competition bikes. The specific mechanical properties prevent kinking, offer chemical resistance to cleaning agents and sludge, and provide consistent low-friction operation over a broad temperature range. Precision coloring supports differentiation within branded or custom series.

Industry compliance standards
