Automotive evaporative emission constraints under Euro 6d and China 6 require fuel tubing to combine low permeation, zinc chloride resistance, and low-temperature flexibility. Qualification of Rilsan BESNO P210 TL in this circuit is conducted against SAE J2260, ISO 13775-2:2016, and DIN 73378, with tensile properties verified by ISO 527-2:2012 and melt consistency controlled by viscosity number 210 cm³/g according to ISO 307:2019. Permeation testing is typically performed with Fuel C or CE10 at 40°C–60°C; the complete tube assembly is evaluated for permeation rates below the OEM-defined limit, often <10 g/m²/day for fuel liquid lines and <15 g/m²/day for vapour return constructions. In multilayer liquid fuel lines, the material is not used as the conductive wetted layer because the natural grade lacks the carbon black loading required for electrostatic dissipation; instead, it is selected as the outer jacket or intermediate tie layer. The formulation addition ratio is 100 wt% Rilsan BESNO P210 TL for monolayer vapour return tubes, while in coextruded five-layer fuel lines it is charged at 50–70 wt% of the total wall mass, with an inner conductive polyamide layer at 10–20 wt% and an EVOH or PVDF barrier layer at 3–8 wt%. Pre-drying in a desiccant dryer at 80°C–90°C for 4–6 h to a moisture content below 0.08% is mandatory when ambient relative humidity exceeds 60%. Production is carried out on single-screw extruders of 25:1–30:1 L/D fitted with barrier screws and screen packs of 60/120 mesh, with melt temperature held at 225°C–245°C and die temperature at 230°C–240°C. Calibration is performed by vacuum sizing or internal air-gap pressure for corrugated constructions; wall thickness ranges from 0.5 mm to 1.5 mm depending on pressure rating. Terminal finished product types include fuel filler neck vent tubes, canister vapour return lines, multilayer liquid fuel feed and return lines, and quick-connector jacket layers in underbonnet fuel circuits.
Because air brake tubing in commercial vehicles must retain burst strength after heat ageing and survive low-temperature impact at -40°C, Rilsan BESNO P210 TL is used as the primary monolayer wall in such circuits. The grade’s moisture absorption at 23°C/50% RH is low relative to PA6 and PA66, limiting changes in dimensional stability and burst pressure in humid winter operating conditions. Compliance is established under SAE J844, FMVSS 571.106, and ISO 7628:2018, with Charpy notched impact measured by ISO 179-1:2023. The addition ratio in monolayer tube production is 100 wt% Rilsan BESNO P210 TL; where external colour coding is required, a PA11-compatible masterbatch is employed at 1.0–2.0 wt%, and no external plasticiser is added. Processing on a grooved-feed single-screw extruder of 24:1–30:1 L/D uses a melt temperature of 230°C–250°C, vacuum sizing with closed-loop diameter control, and a screw-speed profile that keeps material residence time below 10 min. Dimensional control is maintained at ±0.05 mm on outer diameter for 8–16 mm tube sizes, with wall thickness between 1.0 mm and 1.5 mm. Burst testing at 60°C is conducted at a minimum of 4× the rated working pressure according to SAE J844. Terminal finished products include compressed air brake lines for heavy-duty trucks, trailers, and buses, suspension levelling lines, and auxiliary air circuits for gearshift and cab systems.
For medium-pressure hydraulic hose construction, Rilsan BESNO P210 TL is applied as the inner liner in a two-stage crosshead extrusion operation. The liner is first extruded onto a cooled mandrel, followed by high-tenacity polyester or aramid fibre braiding and then outer cover extrusion. The inner liner must withstand mineral oil and synthetic ester hydraulic fluids at working temperatures up to 80°C, with hydrostatic verification under ISO 1402:2009 and product qualification against ISO 3949 or SAE J517. The formulation addition ratio for the liner is 100 wt% Rilsan BESNO P210 TL; wall thickness is specified as 0.25 mm for 6 mm inner diameter hose, rising to 1.00 mm for 25 mm inner diameter constructions, with the PA11 liner typically representing 20–35 wt% of the finished hose mass. Melt temperature during liner extrusion is controlled at 225°C–245°C, mandrel temperature at 20°C–40°C, and the liner is immediately cooled to achieve ±0.05 mm wall tolerance before braiding. Terminal finished products include hydraulic brake and clutch assemblies for off-highway equipment, implement hydraulic lines in agriculture, and medium-pressure industrial power unit hose assemblies. Processing is not recommended with phosphate ester hydraulic fluids because ester-induced swelling can degrade liner mechanical properties; published data for long-term liner performance with HFD-R fluids is limited.
Unbonded flexible risers and flowlines employ extruded PA11 as the internal pressure sheath over a stainless steel carcass, because the polymer combines resistance to produced hydrocarbon mixtures with low water swell and resistance to cracking under cyclic bending. Qualification is performed under API Spec 17J and associated test protocols, including ISO 527-2:2012 for tensile properties, ISO 9080:2012 for long-term hydrostatic strength, and ISO 1133-1:2022 for melt viscosity control. The formulation addition ratio is 100 wt% Rilsan BESNO P210 TL without filler, pigment, or reclaim; sheath thickness is a design parameter determined by bore pressure, annulus condition, and bend radius, commonly 4–12 mm for pipe internal diameters from 2 in to 8 in. Extrusion is continuous on a high-output single-screw extruder of 30:1–36:1 L/D, with melt temperature 220°C–240°C, crosshead die temperature 225°C–235°C, and water-spray cooling followed by online ultrasonic thickness scanning and high-voltage spark testing at 10–25 kV according to sheath thickness. Thick sheaths above 8 mm wall typically use a melt pump to reduce output pulsation and maintain wall-thickness variation within ±2%. Terminal finished product types include static and dynamic offshore flexible risers, flowlines, jumpers, and export line segments. The operational boundary for PA11 pressure sheaths in wet hydrocarbon service is generally below 70°C; above this temperature, hydrolysis kinetics of the polyamide backbone accelerate, and sour-service qualification for elevated H₂S partial pressures requires specific testing because published data for this exact grade in high-acid-gas environments is limited.
In marine and offshore cable sheathing, the conversion of Rilsan BESNO P210 TL differs from polyethylene or PVC jacketing because the semi-flexible polyamide melt exhibits higher shrinkage and a sharper crystallisation exotherm, requiring dedicated screw geometry, longer cooling, and closed-loop diameter control. The material is processed as the sheathing layer for shipboard and platform control, instrumentation, and power cable jackets where resistance to diesel, hydraulic oil, and mechanical abrasion is specified. Compliance is evaluated under IEC 60092-359:2015, IEEE 1580:2010, and flame propagation test IEC 60332-1-2:2004, with halogen content verified by IEC 60754-1:2011 and smoke density by IEC 61034-2:2005. The formulation addition ratio is 100 wt% Rilsan BESNO P210 TL for the jacket layer; UV-stabilised masterbatch is added at 0.5–1.5 wt% for cables installed on open decks or in tropical marine exposure. Jacket extrusion is performed on a 30:1 L/D single-screw extruder with a barrier screw and pressure die at melt temperature 225°C–245°C; jacket thickness ranges from 0.8 mm for 5 mm core diameter to 2.5 mm for 35 mm core diameter, followed by water-trough cooling at 20°C–40°C and online spark testing. Terminal finished products include marine control and instrumentation cables, offshore topside power cable jackets, and rail vehicle data and control cable sheaths. This grade is not inherently flame retardant; constructions requiring IEC 60332-3-24 vertical flame propagation on bunched cables may require additional flame-retardant compounding that can reduce low-temperature flexibility.
Industrial paint circulation and solvent-laden air systems impose simultaneous demands for solvent resistance, dimensional stability during intermittent hot flushing, and flexibility at low installation temperatures. Rilsan BESNO P210 TL is used in monolayer tube extrusion for such circuits where the process fluid is compatible with polyamide 11, including aliphatic hydrocarbons, mineral oils, glycols, and mild organic solvents. Compliance is assessed by hydrostatic testing under ISO 1402:2009, with pressure equipment conformity under 2014/68/EU for assemblies installed in the European Economic Area; tensile verification is performed according to ISO 527-2:2012. The addition ratio for the tube wall is 100 wt% Rilsan BESNO P210 TL, with carbon black masterbatch at 1.5–2.5 wt% only when ultraviolet exposure is expected; no plasticiser or filler is included. Extrusion is conducted with internal air-gap calibration or vacuum sizing on a single-screw extruder of 25:1–30:1 L/D, with melt temperature 220°C–240°C, wall thickness 1.0–2.0 mm, and outer diameter 6–16 mm. Drying to below 0.08% moisture is required before extrusion when ambient relative humidity exceeds 60%. Terminal finished products include paint spray transfer lines, ink supply tubes for printing machines, solvent recovery lines, and pneumatic conveying tubes for powder-coating workshops. The material is not recommended for continuous exposure to strong oxidising acids, phenol, or formic acid at elevated temperatures; published data for these specific configurations is limited.

Arkema Rilsan BESNO P210 TL is a medium-viscosity polyamide 11 (PA11) grade supplied as natural pellets and produced from castor oil. The grade belongs to the plasticized BESNO P series; the suffix TL designates heat and light stabilization. The polymer has a bio-based carbon content commonly reported as 100 % under ASTM D6866, with density in the range 1.02–1.04 g/cm³ when measured according to ISO 1183-1. The crystalline melting temperature is near 189 °C under ISO 11357-3. The material is specified for extrusion of small-diameter pneumatic tubing, cable sheathing, and injection moulded connectors because PA11 combines low equilibrium water uptake, resistance to hydrocarbon and zinc chloride stress cracking, and ductility below 0 °C. Unlike unplasticized PA11 grades, the P210 TL system displays lower tensile modulus, higher elongation at break, and reduced heat distortion temperature. These differences are controlled by the plasticizer content and are therefore central to design selection when a flexible, cold-impact-resistant polyamide is required.
Plasticization lowers the glass transition temperature and tensile modulus while increasing melt-chain mobility. In dry-as-moulded specimens, this shift changes the failure mode from brittle fracture to yield-and-draw behaviour, but it also reduces heat distortion temperature relative to unplasticized PA11 grades. On production-scale single-screw extruders with L/D 30:1 and grooved feed sections, the grade is processed with barrel zones from 220 °C to 250 °C and a die temperature held at 230–250 °C. Screw speed is adjusted to maintain melt pressure below 350 bar before the breaker plate; excursions above this limit indicate filter blockage or excessive regrind accumulation. Pre-drying is mandatory when surface moisture exceeds 0.15 %. Drying at 80–90 °C for 4–8 h in a desiccant dryer with a dew point below -30 °C is typical. Insufficient drying produces surging at the extruder head and ovality drift downstream of the calibration sleeve. In injection moulding, a melt temperature of 235–255 °C and a mould temperature of 40–80 °C are used for thin-wall parts. Early ejection from a cold mould results in sink marks and elevated post-shrinkage. Regrind levels above 20 % may alter the plasticizer distribution and reduce notched impact resistance, so lot-to-lot rheology should be checked when regrind is introduced at high ratios.
The stabilizer package in the TL suffix retards thermo-oxidative chain scission during prolonged residence at melt temperature, but it does not eliminate the need for purging during shutdowns. Melt temperatures above 260 °C accelerate discoloration and molecular weight loss. Capillary rheometry shows shear-thinning behaviour typical of plasticized polyamide; therefore screw speed and back pressure are adjusted to limit shear heating rather than relying solely on barrel set points. In tube extrusion, die land length ratios of 10:1–20:1 and draw-down ratios of 1.2:1–2:1 are used to control axial orientation. Vacuum sizing pressure is commonly held between -0.2 bar and -0.6 bar. Failure modes observed on manufacturing lines include melt fracture at die exit when die temperature falls below 225 °C, and surface pitting when the melt enters the calibration sleeve with more than 0.15 % residual moisture.
Typical data for plasticized medium-viscosity PA11 are shown in Table 1. These ranges reflect dry-as-moulded specimens conditioned at 23 °C and 50 % RH for less than 1 h; actual lot values depend on plasticizer level and stabilizer package. Design calculations should use values from the current manufacturer certificate rather than midpoint literature values.

Moisture conditioning changes these properties. After equilibrium water uptake, tensile modulus and yield stress decrease, while elongation and impact resistance increase. The magnitude of the shift is lower for PA11 than for PA6 or PA66, which is one reason the material is used in humid or wet environments where dimensional stability and electrical insulation performance are required. The plasticized P210 TL system should nevertheless be tested at the expected service moisture level because plasticizer migration may offset the moisture-induced toughening effect in long-term exposure.
Extrusion lines producing SAE J844 air brake tubing from Rilsan BESNO P210 TL use a vacuum sizing sleeve and a calibrated water bath maintained at 15–25 °C. The tube is drawn at a controlled haul-off ratio; excessive draw ratio raises axial orientation and may reduce burst strength when tested under ISO 7628. On cable sheathing lines, the melt is filtered through a screen pack of 200–400 µm and extruded over a conductor preheated to 80–120 °C. Because the grade is halogen-free, the sheathing is evaluated for acid gas generation under IEC 60754-1 and for flame propagation under IEC 60332-1-2; smoke density depends on plasticizer content and must be verified per final wall thickness. In automotive fuel vapor lines, the PA11 layer is coextruded with an ethylene vinyl alcohol barrier layer and an outer PA12 or PA612 layer. Evaporative emission performance is determined by the barrier layer, while the PA11 layer contributes chemical resistance and cold impact performance. Permeation testing is conducted under SAE J2260 or equivalent vehicle-specific procedures.
PA11 is selected over PA12 where higher continuous-use temperature and higher crystalline melting point are required, and selected over PA6 or PA66 where dimensional stability in humid environments is critical. Moisture uptake affects the dielectric constant and volume resistivity of PA6 and PA66 more strongly than PA11. Table 2 summarizes typical dry-as-moulded comparative ranges for unplasticized base resins; the plasticized P210 TL grade exhibits lower tensile modulus and higher elongation than the unplasticized PA11 values shown.
| Material | Density, ISO 1183-1 | Melting point, ISO 11357-3 | Saturation water uptake at 23 °C, ISO 62 | Tensile modulus dry, ISO 527 |
|---|---|---|---|---|
| PA11 base resin | 1.03–1.04 g/cm³ | 185–190 °C | 1.6–2.0 % | 1100–1300 MPa |
| PA12 base resin | 1.01–1.02 g/cm³ | 175–180 °C | 1.4–1.7 % | 900–1100 MPa |
| PA6 base resin | 1.13–1.15 g/cm³ | 220–225 °C | 9.0–10.0 % | 2800–3200 MPa |
| PA66 base resin | 1.13–1.15 g/cm³ | 255–265 °C | 8.0–9.0 % | 3000–3500 MPa |
Compared with PA12, PA11 shows a higher crystalline melting point and higher bio-based content, but PA12 offers lower saturation water uptake and slightly lower density. Compared with PA6 and PA66, PA11 maintains mechanical properties after moisture conditioning with a smaller loss in modulus; PA6 and PA66 provide higher dry stiffness and higher heat deflection temperature. The choice between BESNO P210 TL and an unplasticized PA11 depends on whether the application tolerates the reduced heat distortion temperature and lower modulus of the plasticized system. For connectors requiring high snap-fit retention at elevated temperature, an unplasticized or glass-reinforced PA11 grade may be substituted; for tubing subjected to cold impact and tight bend radii, the plasticized P210 TL grade is typically preferred.
Offshore flexible pipe liners based on PA11 are qualified by long-term ageing in crude oil and gas condensate under API 17J or API 17K programmes. Rilsan BESNO P210 TL may be used in such liners when the plasticizer does not migrate excessively into the transported fluid; extraction testing under ISO 6427 should be used to measure plasticizer loss. The grade is also applied in automotive fuel vapor lines where evaporative emission requirements under CARB LEV III or EPA Tier 3 necessitate low-permeation multilayer constructions. In these systems, the PA11 layer is coextruded with an ethylene vinyl alcohol barrier layer and an outer PA12 or PA612 layer to combine chemical resistance with low hydrocarbon permeation. Incompatibility with concentrated strong acids and phenols at elevated temperature is a known operational boundary; stress-cracking evaluation under ISO 22088 should be conducted when the fluid contains salts such as calcium chloride or zinc chloride. Published data for this specific P210 TL configuration in high-pressure sour-service flexible pipe liners is limited, so qualification must rely on lot-specific mechanical and ageing data rather than generic PA11 data.
