Applications of EMS-Grivory Grilamid® L 20 HL black 9563 PA12 in Industrial Manufacturing

EMS-Grivory Grilamid® L 20 HL black 9563, a high-performance polyamide 12 (PA12), provides exceptional chemical resistance, dimensional stability, and low moisture absorption for demanding industrial and OEM applications. As the original manufacturer, we supply this grade directly to downstream producers operating advanced processing lines across several focused manufacturing sectors with proven PA12 adoption.

1. Automotive Fluid Handling Systems

Automotive suppliers use this PA12 grade in high-pressure multi-layer tubing for fuel, brake, and SCR urea lines. The material’s inherent resistance to automotive fluids, combined with precision melt processing, ensures reliability even under engine compartment thermal cycling and underhood vibration conditions. The black 9563 pigment batch offers UV stabilization and prevents light-induced degradation in exposed installations.

Industry compliance standards

• ISO 7628 (Road vehicles – Thermoplastic tubing for use in air braking systems)
• SAE J2260 (Nonmetallic Fuel Tubing, Road Vehicle – Design, Test Methods, and Performance Requirements)
• UN ECE R67 (Approval of LPG Equipment and Installations in Vehicles)
• OEM-specific material and odor emission standards (e.g., VW TL 527, Daimler DBL 5556)

Typical usage ratio

• 70–100% of polymer matrix in single- or multi-layer extrusion, adjusted for co-extrusion with adhesive tie layers or EVOH barrier layers if permeation limits apply.

Downstream process integration

• Direct feeding to precision pipe extrusion lines, requiring controlled melt viscosity and pellet drying. Processors may blend with impact modifiers for dynamic applications or use in multi-layer co-extrusion with tie adhesives and barrier resins.

Final product types

• Fuel lines
• SCR/AdBlue urea delivery tubing
• Brake and clutch lines
• Hydraulic and pneumatic tubing assemblies

2. Electrical and Electronics Cable Sheathings

The grade’s superior insulating properties and flame resistance make it a favored selection for cable insulation and jackets in data, power, and sensor cabling for high-mobility and outdoor uses. The black formulation complies with UV resistance needs in exposed wiring harnesses. Downstream extrusion processes rely on the polymer’s consistent melt profile to ensure defect-free cable coatings at industrial line speeds.

Industry compliance standards

• IEC 60332-1 (Flame Retardant Test for Cables)
• ISO 6722 (Road vehicles – 60 V and 600 V thin-wall low-voltage cables)
• UL 1581 (Reference Standard for Electrical Wires, Cables, and Flexible Cords)
• RoHS 2 (Restriction of Hazardous Substances)

Typical usage ratio

• 90–100% as primary jacket resin during extrusion. Flame retardants and process lubricants may account for up to 5% depending on regulatory fire safety targets.

Downstream process integration

• Feeds directly into continuous extrusion lines for power or signal cable jacketing. Operators may incorporate compounding steps for flame retardancy or color, but the black 9563 masterbatch reduces the need for additional pigmentation.

Final product types

• Automotive wire harness insulation
• Industrial robot cable jackets
• Sensor wiring sheathings
• Outdoor telecommunications cables

3. Pneumatic and Hydraulic Hose Jackets

OEMs manufacturing pneumatic and hydraulic hose systems employ this PA12 as a primary outer jacket to resist mechanical abrasion, mineral oils, and chemicals in industrial automation. The black 9563 coloration delivers anti-static and UV protection in exposed environments—from factory floors to mobile equipment, ensuring system reliability and long-term compliance with safety guidelines.

Industry compliance standards

• ISO 3949 (Plastics hoses and hose assemblies – Thermoplastics hoses for hydraulic fluids)
• EN ISO 8033 (Rubber and plastics hoses – Determination of adhesion between components)
• REACH Regulation (EC) No 1907/2006 (Substance Registration & Safety)
• RoHS compliance for electrical interfacing hoses

Typical usage ratio

• Typically 60–100% as outer sheath via extrusion; formula may include UV stabilizers (up to 2%) or anti-static additives, depending on installation site risk assessment.

Downstream process integration

• Used in primary and secondary extrusion over reinforcement braids or as a final layer on co-extruded multi-layer hose structures; pellet drying critical for hydrolysis resistance.

Final product types

• High-pressure hydraulic hoses
• Pneumatic supply lines
• Lubricant delivery hose assemblies
• Protective conduits for factory automation

4. Industrial 3D Printing Applications (Fused Filament Fabrication)

Engineering teams in additive manufacturing utilize this black PA12 for functional components requiring structural integrity and dimensional accuracy. Its low warpage and good inter-layer adhesion support serial production runs of complex parts, such as jigs, connectors, and housings, with critical long-term chemical and UV exposure requirements for automotive and electronics applications.

Industry compliance standards

• ASTM F3091/F3091M (Standard Specification for Additive Manufacturing of Plastic Materials)
• EN ISO/ASTM 52900 (Additive manufacturing – General principles and terminology)
• OEM-specific 3D printing and end-use specification (e.g., VW 50190 for rapid prototyping plastics)
• Material traceability requirements (ISO 9001, VDA 6.3 production quality)

Typical usage ratio

• 100% filament core, with black masterbatch pigment content preset from resin stage. No further blending required by printer operators unless modifying for conductive or anti-static grades.

Downstream process integration

• Extruded as high-tolerance filament or directly processed in selective laser sintering (SLS) and fused filament fabrication (FFF); stable melt viscosity ensures consistent deposition and dimensional repeatability across print beds.

Final product types

• Custom-made cable clamps and electrical enclosures
• Automotive engine bay routing brackets
• Equipment-specific jigs and fixtures
• Prototyping components subject to chemical or outdoor conditions

5. Precision Injection Molded Technical Components

Manufacturers of high-precision technical parts choose this PA12 grade for its melt flow consistency, toughness, and resistance to fuels, oils, and chemical agents. Black 9563 pigment ensures part aesthetics and UV stability in outdoor assemblies. Producers rely on controlled thermal and moisture conditioning prior to molding, matching stringent dimensional tolerance requirements in end-use assemblies for the automotive and industrial sectors.
