Applications of Arkema Rilsamid® AECNO TL PA12 in Industrial Manufacturing

Arkema manufactures Rilsamid® AECNO TL PA12 as a high-performance polyamide used in demanding technical applications. This material finds adoption across several precision manufacturing sectors requiring distinct compliance, precise formulation, and rigorous process control to deliver quality downstream products.

1. Automotive Fuel Line and Pneumatic Tubing Manufacturing

Automotive component producers use this polyamide grade as a key engineering resin for multilayer fuel lines and pneumatic air brake tubing. Its inherent chemical resistance and impact strength support compliance with stringent emissions and safety standards. Compounders blend the resin with specified impact modifiers and UV stabilizers for exterior lines, adjusting the loadings to local climate exposure. Downstream, extrusion processes incorporate strict moisture content control to avoid melt defects, with dimensional checks aligning with automotive tolerances. Most end products undergo 100% in-line integrity testing before use in automotive assembly.

• SAE J2260 (Non-metallic Fuel System Tubing)
• ISO 7628 (Road vehicles – Air brake tubing)
• FMVSS 106 (Brake hoses)
• IATF 16949 (Automotive Quality Management)

Typical usage ratio

• 60-100% by weight as the main polymer in tubing; blends adjust for flexibility, chemical exposure — lower end used in multilayer systems with tie layers, higher for monolayer lines.

Downstream process integration

• Material dried to <0.1% moisture, gravity-fed to twin-screw extruder, compounded with functional additives, extruded through calibrated dies, cooled, laser-marked, and spooled for cutting.

Final product types

• Automotive fuel lines for gasoline/diesel vehicles
• Compressed air brake lines for trucks/buses
• SCR (Selective Catalytic Reduction) urea delivery tubing
• Vapor recovery and vent lines in hybrid powertrains

2. Industrial Powder Bed Fusion (3D Printing) Feedstock Production

Specialty compounders and 3D printing service bureaus utilize our PA12 resin for powder bed fusion feedstocks. Its particle size distribution and melting point enable layer-by-layer sintering, supporting intricate geometries and mechanical performance in printed parts. Sieving and powder treatment regulate flow characteristics, while cleanroom blending prevents contamination that could compromise build quality. Final powder pack-out incorporates batch traceability, with end users demanding consistent lot reproducibility for short-run series and critical technical prototypes.

Industry compliance standards

• ASTM F3091 (Additive Manufacturing for Polyamides)
• ISO/ASTM 52900 (Additive Manufacturing General Principles)
• ISO 9001 (General Quality Management)

Typical usage ratio

• 90-99% PA12 by mass in the powder blend with minor additives (flow aid, anti-caking), with occasional mix-in of colored masterbatch <2% for custom part identification.

Downstream process integration

• Granulate cryogenically ground, classified by air jet sieving, antistatic blended, pre-packed in moisture-tight containers, loaded into SLS (Selective Laser Sintering) or Multi Jet Fusion equipment at the customer site.

Final product types

• Functional end-use parts for machinery
• Rapid prototyping and jigs for assembly lines
• Aerospace brackets with mechanical load requirements
• Small-batch replacement parts for industrial equipment

3. Food and Beverage Fluid Transfer Equipment Components

Processors serving the food and beverage packaging sectors employ this material for blow-molded and injection-molded fluid handling parts. Polymers are selected based on compliance with migration limits and sanitation cycles outlined by regulatory agencies. Additives for hydrolysis and detergent resistance are formulated in precise amounts to support repeated sterilization. Production adheres to GMP and HACCP for traceability, and each batch is subject to extractables testing under simulant exposures dictated by local food-contact legislation.

Industry compliance standards

• EU Regulation No. 10/2011 (Plastics in contact with foodstuffs)
• FDA 21 CFR 177.1500 (Nylon resins for food contact)
• GMP Regulation (EC) 2023/2006
• NSF/ANSI 51 (Food equipment materials)

Typical usage ratio

• 85-100% as the polymer phase in tubing, manifold housings, or connectors; lower range for multi-material parts with soft overmolding, higher in monolithic food-contact components.

Downstream process integration

• Raw pellets transferred to injection or blow-molding lines, processed at controlled melt temperatures, finished products exposed to sanitizing cycles, and QC tested for leachables.

Final product types

• Dairy and beverage dispense lines
• Valve bodies for automated filling machines
• Sanitary connectors and quick couplings
• Filter housings for industrial beverage systems

4. Electrical and Electronics Cable Sheathing

Cable manufacturers rely on the mechanical stability and flame resistance of this PA12 grade when producing sheathing and insulation for specialized communication and sensor cables. Compounds incorporate halogen-free flame retardants and color antimigrants for safety in enclosed installations, while Rilsamid® AECNO TL ensures long-term flexibility and moisture barrier properties. Processing lines operate with close monitoring of melt flow rates, and outputs are subject to spark testing and dielectric breakdown inspection to certify cable lot conformity.

Industry compliance standards

• IEC 60332-1-2 (Flame retardant performance)
• UL 1581 (Reference Standard for Electrical Wires)
• RoHS Directive (2011/65/EU restricts hazardous substances)
• ISO 9001 (Quality Management Systems)

Typical usage ratio

• 60-95% as the base matrix; ratio varies with flame retardant or EMI shielding content for required cable class.

Downstream process integration

• Pre-dried and metered PA12 compound extruded over conductors via crosshead dies, cooled in calibration baths, color-striped as required, coiled, and cut to spec before terminal fitting.

Final product types

• Industrial sensor cable jackets
• Automotive wiring harness insulation
• Control cable sheathing for robotics
• Data communication cables in factory settings

5. Oil and Gas Onshore and Offshore Rigid Pipe Linings

Pipe manufacturers utilize PA12 for inner linings of steel or composite pipes in oil and gas transmission. Its impermeable structure resists hydrocarbon permeation and supports pressure cycling in aggressive downhole and subsea environments. Raw material is compounded with impact modifiers and processed by extrusion or rotational lining, depending on pipe diameter and wall thickness requirements. All produced pipe sections undergo hydrostatic and permeability testing to ensure compliance with regulatory and end-user project specifications.
