Applications of EMS-Grivory Grilamid® L 20 EC PA12-CD25 in Industrial Manufacturing

EMS-Grivory Grilamid® L 20 EC PA12-CD25 is widely implemented in advanced industrial sectors requiring specialty polyamides for high-performance plastic components. Below, we detail authentic application scenarios where this material consistently meets rigorous industrial, regulatory, and technical demands.

1. Automotive Brake and Fuel Line Tubing

Automotive component manufacturers specify this polyamide grade for producing lightweight brake and fuel line tubing due to its excellent chemical resistance, stable dimensional properties, and compatibility with advanced hydroforming and extrusion processes. The demand for hydrolysis resistance and low permeability supports long-term service in both gasoline and alternative fuel vehicles.

Industry compliance standards

• SAE J844 (Nonmetallic Air Brake Tubing)
• ISO 7628 (Road vehicles – Polyamide tubing for air braking systems)
• FMVSS 106 (Brake Hoses, USA)
• EC 2007/46/EC (EU Vehicle Type Approval)

Typical usage ratio

• 100% of base polymer for monolayer systems
• 30–70% blend in multilayer extrusion, adjusted to required permeability and mechanical targets

Downstream process integration

• Material enters as resin pellets in the extrusion segment, often with pre-conditioning and gravimetric blending to control wall thickness, flexibility, and inner layer cohesion. In multilayer lines, it bonds to tie layers or barrier materials via co-extrusion dies.

Final product types

• Fuel delivery tubes (gasoline, diesel, biodiesel, bioethanol lines)
• Air brake hoses
• Hydraulic clutch lines
• SCR (Selective Catalytic Reduction) urea lines

2. Pneumatic and Hydraulic Control Systems

Suppliers of control systems for manufacturing and automation select this polyamide for fluid transmission and protective sheathing. Its low extractables, exceptional impact strength, and stable performance at elevated temperatures underpin usage in safety-critical pneumatic and hydraulic assemblies, particularly in food processing and packaging machinery.

Industry compliance standards

• EN ISO 4413:2010 (Hydraulic fluid power systems)
• DIN 74324 (Polyamide Tubing for Pneumatic Brakes)
• FDA CFR 21 §177.1500 (PA polymer compliance for food-contact where required)
• ISO 8573 (Compressed air systems – Quality classes)

Typical usage ratio

• 90–100% PA12 for pneumatic lines requiring continuous flexibility and pressure resistance
• Blended 40–60% with additives for extra slip or flame retardancy in specialty lines

Downstream process integration

• Introduced as granules to mono-extrusion or multi-layer co-extrusion; upstream drying step ensures low moisture content before precision tubing drawing and online diameter QC; compounded in the melt with color/antistatic masterbatches if required.

Final product types

• Pneumatic actuator and solenoid valve tubing
• Food-grade compressed air pipes
• Sensor and wiring protection conduits
• Hydraulic pilot lines

3. Cable Sheathing for Industrial Automation

The heat-stabilized, flexible nature of this PA12 grade supports extrusion of durable cable sheathing and jacketing for moving machine parts and robotic systems. End users look for high abrasion resistance, reliable dielectric properties, and tight dimensional consistency—especially for cables exposed to oils, lubricants, and cyclic bending.

Industry compliance standards

• UL 1581 (Reference standard for electrical wires, cable insulation and jacketing)
• IEC 60228 (Conductors of insulated cables)
• RoHS Directive 2011/65/EU
• CE marking for industrial control products

Typical usage ratio

• 95–100% for single-layer jacketing of drag-chain cables
• 30–60% as intermediate sheath layer in multi-layered high-flex cables

Downstream process integration

• Processed via thermoplastic extrusion directly onto cut copper or fiber assemblies, frequently paired with cross-head extrusion dies for concentric wall formation and online laser measurement for outer diameter validation.

Final product types

• Drag-chain automation cables
• Ethernet and data bus cables for industrial networks
• Multi-core servo cables
• Robotic sensor cables exposed to chemical coolants

4. Sports Equipment Manufacturing

Producers of high-end sports gear and cycling components employ this specialty polyamide for lightweight frames, gear housings, and impact-resistant design elements where fatigue life, dimensional accuracy, and chemical compatibility with lubricants and sweat are critical. Its stable molding performance and color retention support visible parts with custom finishes.

Industry compliance standards

• ISO 4210 (Cycles - Safety requirements for bicycles)
• EN 957 (Stationary training equipment – Safety requirements and test methods)
• REACH Regulation (EC) No 1907/2006
• ISO 10993-5 (Cytotoxicity for fitness applications with skin contact)

Typical usage ratio

• 100% base polymer in injection molding for maximum strength-to-weight applications
• Up to 30% filled with glass or carbon fibers as specified by part performance targets

Downstream process integration

• Delivered as pre-dried pellets for injection molding; dosing into high-cavitation molds; short cycle times facilitate mass production of frames and load-bearing components; in-mold coating integration possible in single production flow.

Final product types

• Bicycle derailleur hangers and cable guides
• Inline skate chassis
• Protective housings for electronic training equipment
• Racket frames and stringing bridge inserts

5. Industrial Additive Manufacturing (3D Printing) Filaments

Filament and powder suppliers for industrial 3D printing incorporate this PA12 for high-performance functional prototyping and low-volume end-use parts. Consistent sintering and melt rheology characteristics enable both FDM/FFF filament and powder bed fusion applications, addressing mechanical requirements across medical device trialing and manufacturing jigs.

Industry compliance standards

• ASTM F3091 (Standard specification for Additive Manufacturing - Polyamide)
• ISO/ASTM 52900 (Additive manufacturing – General principles)
