On duplex stainless steel and carbon steel valve bodies destined for splash-zone and subsea service, Arkema Rilsan BMNO P40 TLD is applied over a fusion-bonded epoxy primer with a dry film thickness of 60–100 µm, then fused at a substrate surface temperature of 250–280°C. The processing window is narrow because the PA11 layer must exceed its crystalline melting point of 189–190°C by at least 30°C to level into machined thread roots and flange serrations, while the epoxy primer remains below its degradation threshold. Surface temperature is checked with a calibrated contact pyrometer having ±2°C repeatability; below 250°C the powder fails to wet the primer and intercoat adhesion drops below 4B under ASTM D3359-17 Method B, while above 280°C primer volatiles cause microbubbles and holiday counts above 2 per m² when tested at 5 kV/mm under ASTM D5162. Target dry film thickness is 300–500 µm using corona electrostatic guns at 60–80 kV or fluidised-bed immersion for 3–5 s. Compliance is evaluated against ISO 12944-6 category C5M and NORSOK M-501, with salt-spray exposure to ISO 9227 for 3,000 h without scribe creep exceeding 2 mm, impact resistance to ISO 6272-1 at 5 J, and Taber abrasion to ASTM D4060 with CS-17 wheels and 1,000 g load showing mass loss below 25 mg. Terminal parts include subsea ball valves, pipe spools, riser clamps, flanged fittings, and pump casings. The test matrix used for batch release is shown below.
| Property | Test designation | Acceptance criterion |
|---|---|---|
| Dry film thickness | ISO 2178 | 300–500 µm |
| Adhesion | ASTM D3359-17 Method B | ≥4B |
| Holiday detection | ASTM D5162 | ≤2 holidays per m² at 5 kV/mm |
| Salt spray | ISO 9227 | 3,000 h scribe creep ≤2 mm |
| Impact resistance | ISO 6272-1 | 5 J no cracking |
On automated lines for seatbelt pre-tensioner brackets and window regulator clips, degreased and shot-blasted spring steel parts are preheated to 260–300°C in a continuous tunnel oven with a residence time of 6–10 min, then coated with BMNO P40 TLD by corona electrostatic spraying at 40–70 kV. The applied layer of 150–250 µm must survive 200,000 wear cycles in a seatbelt guide loop without exposing the steel substrate, so the powder is dry-blended with 0.4 parts per hundred resin of hydrophobic fumed silica and 0.3 parts per hundred resin of carbon black for static charge dissipation; no plasticiser is added because it raises the coefficient of friction above the required 0.18–0.25 measured by ISO 8295 against a chrome-plated counterface. Post-fusion at 210°C for 90–120 s in an infrared oven produces a matte surface with pencil hardness F to H under ISO 15184. Corrosion resistance is tested to ISO 9227 for 720 h without red rust, and abrasion resistance to ASTM D4060 with CS-17 wheels and 500 g load accepts mass loss below 30 mg. Interior-application compliance is managed under IATF 16949:2016, emission testing to VDA 277 for total VOC emissions below 100 µg C/g, and seatbelt assembly performance to FMVSS 209. Terminal products include seatbelt guide loops, pretensioner brackets, ball stud covers, and window regulator clips. Closed hoppers are required to keep powder moisture below 0.1%; material exposed to plant air for more than one shift is re-dried at 80°C for 2 h before returning to the hopper.
Cast iron gate valve wedges and service saddle linings are coated by fluidised-bed dip after machining and abrasive blasting to ISO 8501-1 Sa 2½ with a surface roughness Rz 60–100 µm. The casting is heated to 300–330°C in a chain-driven oven with a soak time of 20–30 min, dipped for 3–5 s, and post-fused at 200–220°C for 3 min to reduce open porosity below 0.5% by volume on cross-sections. The resulting thickness of 200–350 µm is selected because PA11 shows saturated water absorption near 1.8–1.9% by ISO 62, and thickness above 350 µm can develop internal stress during long-term wet-dry thermal cycling between 5°C and 60°C. The formulation is 100.0 parts by weight BMNO P40 TLD and 0.1–0.3 parts silica anti-caking agent; no pigment, filler, or solvent is added. Potable-water compliance is assessed under NSF/ANSI/CAN 61 Section 4, BS 6920 Part 1, and AS/NZS 4020, with migration testing according to EN 13130-1 and overall migration limits under Regulation (EU) No 10/2011; finished parts are subjected to a 5 kV/mm holiday test under ASTM D5162 and a 6-bar hydraulic pressure test. Terminal products include drinking water valve bodies, hydrant internals, water meter housings, and potable water pump impellers. Solvent-based cleaning agents must not be used on the fused lining because surface microcrazing can occur after extended contact; continuous hot water service above 60°C requires additional thermal stabilisation validation.
Outdoor furniture lines running BMNO P40 TLD on aluminium and steel tube frames typically operate at preheat temperatures of 300–330°C for steel and 260–290°C for aluminium, because aluminium's higher thermal conductivity can cool the part below the PA11 melting point before dipping is complete. The powder forms a 250–400 µm coating that resists UV embrittlement and salt-laden coastal air, as tested by ISO 16474-3 UV-A exposure for 1,000 h with a colour difference ΔE below 3.0 and by ISO 9227 neutral salt spray for 1,500 h with no blistering. The dry blend contains 100.0 parts BMNO P40 TLD, 0.3–0.5 parts hindered amine light stabiliser masterbatch, and 2–4 parts UV-stable pigment masterbatch formulated on a PA11 carrier; no liquid plasticisers are added. Hollow sections must be sealed or vented before dipping to prevent expanding air from blowing pinholes through the fused film. Terminal products include park benches, stadium seating, outdoor handrails, and lighting column base covers. After fluidised-bed immersion for 3–6 s, parts are post-fused at 220–230°C for 2–4 min and air-cooled; water quenching is avoided for UV-stabilised colours because rapid cooling can increase surface gloss variation on large flat panels.
Copper and aluminium busbars for battery packs and power distribution units are preheated to 240–270°C before BMNO P40 TLD is applied by electrostatic spray; the powder must encapsulate punched edges and tapped fastener tabs without pulling back from radii below 0.5 mm. Because PA11 has a crystalline melting point of 189–190°C by ISO 11357-3 and a slower crystallisation rate than PA6, the melt remains sufficiently mobile at 220–230°C to flow around edge burrs, but part temperature above 270°C accelerates copper oxidation and adhesion falls below 3B under ASTM D3359-17 Method B. Dielectric strength of a 250–350 µm coating is assessed by ASTM D149 at 20 kV/mm, and the insulation layer is subjected to a 5 kV/mm holiday test under ASTM D5162. The powder is used at 100.0 parts BMNO P40 TLD plus 0.2 parts fumed silica and 0.5 parts antistatic additive; unmodified PA11 is rated UL 94 HB, and flame-retardant masterbatch ratios above 10 parts per hundred resin must be revalidated for adhesion and flexibility. Published data for UL 94 V-0 formulations with BMNO P40 TLD on busbar substrates is limited, so custom validation is required. Relevant design standards include IEC 60664-1 for clearance and creepage and UL 746B for long-term thermal ageing. Terminal products include battery pack busbars, power distribution busbars, motor controller terminals, and capacitor bank interconnects.

Arkema Rilsan BMNO P40 TLD PA11 is a plasticized polyamide 11 extrusion grade supplied in natural pellet form and intended primarily for melt extrusion of mono-layer and thin-wall tubing. The BMNO base resin is a medium-viscosity polyamide 11; P40 denotes plasticizer modification; TLD denotes the tubing-grade processing suffix. Polyamide 11 is synthesised from 11-aminoundecanoic acid derived from castor oil and crystallizes as a semicrystalline polymer with a crystalline melting peak in the range 186–190 °C under ISO 11357-3. Plasticized PA11 tube grades of this family typically exhibit a density of 1.03–1.06 g/cm³ by ISO 1183-1 and water absorption at saturation near 1.9 wt% by ISO 62. These values are not release specifications; published data for the exact BMNO P40 TLD configuration is limited to the supplier datasheet.
The P40 plasticizer reduces tensile modulus, Shore D hardness, and glass transition temperature relative to unplasticized PA11. In tube extrusion, this produces a smaller minimum bend radius without changing the base polymer's hydrocarbon resistance. The exact plasticizer concentration is not disclosed; therefore, lot-specific mechanical testing is required when the tube must meet ISO 7628 or SAE J844 burst and cold-impact requirements. The lower modulus of the P40 system must be compensated by wall-thickness calculation because using unplasticized PA11 data would underestimate creep and burst deformation.
Residual moisture is the primary processing boundary. Polyamide 11 pellets absorb atmospheric moisture, and melt-phase hydrolysis can reduce molecular weight and create wall bubbles if moisture exceeds 0.08–0.10 wt%. Pre-drying in a desiccant-bed dryer at 80 °C for 4–6 h is the standard condition for plasticized PA11 tube grades; the drying time is extended when ambient relative humidity exceeds 60% or when pellets are stored in open containers. Pellet exposure to humid plant air after drying must be limited because PA11 re-adsorbs surface moisture rapidly. At high moisture levels, visible surface defects appear at the sizing die, and the melt loses hydrolytically through chain scission.
Melt temperature at the die entry is usually controlled between 230 °C and 250 °C. Barrel temperature profiles generally rise from 210 °C at the feed zone to 235 °C in the metering zone, but the exact settings depend on screw diameter, L/D ratio, and output rate. General polyamide 11 tube extrusion uses single-screw machines with L/D ratios from 24:1 to 30:1 and compression ratios from 2.5:1 to 3.0:1. Extended hold-up at melt temperatures above 260 °C causes thermo-oxidative degradation, yellowing, and loss of melt strength. The P40 plasticizer reduces melt viscosity relative to unplasticized BMNO, allowing a 10–20% lower screw speed or die pressure on thin-wall tube lines. Melt-pressure variation at the die should be maintained within ±5% to avoid wall-thickness eccentricity. Where a melt pump is installed, pressure fluctuation can be reduced below ±2%, which is critical for thin-wall tolerance classes under ISO 7628.
Tube wall thickness consistency depends on melt-temperature uniformity and screw speed stability. Melt-pressure variation of more than ±5% at the die causes eccentricity and ovality after vacuum sizing. The sizing pressure and cooling bath temperature are typically set between 10 °C and 20 °C for PA11 tube to solidify the outer wall quickly while allowing crystallinity to develop; water bath temperatures below 5 °C can quench-freeze the surface and increase post-extrusion shrinkage. Published Arkema line-specific profiles for BMNO P40 TLD should be consulted because the TLD suffix is associated with downstream sizing behaviour that differs from general-purpose PA11 extrusion grades.
Because the P40 plasticizer shifts the stress–strain response toward higher elongation and lower secant modulus, the product is used in extruded mono-layer tubes where low-temperature flexibility, low moisture uptake, and resistance to aliphatic and aromatic hydrocarbons are required. Applications include compressed-air brake tubing for trucks and buses, fuel-vapor return lines, hydraulic hose sheathing, and cable-protection conduits. In truck air-brake tube, the finished article is validated to SAE J844 or ISO 7628, with cold impact tested at −40 °C and burst-pressure verification at 20 °C and 100 °C. The product is not primarily an injection-moulding grade; connectors and fittings are typically produced from unplasticized or glass-reinforced PA11 grades with different viscosity limits.

The table is a composite of publicly reported typical values for plasticized PA11 tube grades and does not constitute a lot-release specification. Moisture content, plasticizer degree, and test speed affect tensile and impact data. For critical dimensions, obtain the Arkema certificate of analysis and generate statistical process control data on the intended extrusion line. Published data for BMNO P40 TLD specifically is limited to supplier documentation; therefore, property translation from equivalent plasticized PA11 grades should be verified before final part approval.
Replacement of PA12 with P40 PA11 requires recalibration of barrel temperatures and post-extrusion sizing. PA12 melts near 175–178 °C, while PA11 melts near 186–190 °C; therefore, metering-zone set points are usually 15–30 °C higher for PA11. The die-entry melt temperature should be increased stepwise while monitoring melt pressure and tube surface finish. Compared with PA12, PA11 at equal plasticizer level has a higher crystalline melting point and a somewhat higher heat deflection temperature under load, which can be an advantage in under-hood pneumatic lines where peak air temperatures exceed 100 °C. PA12 may retain slightly better dry low-temperature impact and lower water absorption, but PA11 is often selected for zinc chloride road-salt resistance and hydrocarbon resistance. In mono-wall truck air-brake tube, zinc chloride resistance is verified under SAE J844; this requirement frequently drives material selection away from PA6 and PA66 and toward PA11 or PA12.
Transition of an extrusion line from PA12 to PA11 is not a direct drop-in. Residual PA12 domains can form optical gels and weld-line weakness because the two melts have different viscosity-temperature relationships. Screw speed should be reduced by 10–20% during the purge sequence until melt pressure stabilises. The calibration sleeve and vacuum-sizing parameters must be re-optimised because PA11 and PA12 differ in crystallisation rate and post-extrusion shrinkage. In addition, the P40 plasticizer lowers melt viscosity, so the die head may require a smaller die gap or a higher draw ratio to maintain target outer diameter. Published data for this specific transition is limited, so line trials with full thermal and dimensional measurement are required before modifying existing production tooling.
Compared with unplasticized BMNO PA11, the P40 grade exhibits lower tensile modulus and hardness, higher elongation, and improved flexibility at sub-zero temperatures. The trade-off is a measurable reduction in creep resistance and an increase in permeation coefficient because the plasticized amorphous phase permits higher diffusivity. When BMNO P40 TLD is used in fuel-vapor lines, finished-tube permeation must be tested to the applicable standard, such as SAE J30 or DIN 73378, rather than assumed from unplasticized resin data. Multi-layer constructions with barrier polymers may be required if the fuel permeation limit is below the mono-wall PA11 value.
Polyamide 11 is resistant to aliphatic and aromatic hydrocarbons, diesel and gasoline, lubricating oils, greases, and road-salt solutions. In alcohol-containing fuels, PA11 exhibits lower volume swell than PA6 and PA66, which supports its use in fuel-vapor line applications. The plasticizer does not eliminate the base polymer's chemical resistance, but it may increase fuel and oil permeation slightly. The product is not recommended for continuous immersion in concentrated mineral acids, formic acid, phenols, or strong oxidizing agents. Prolonged contact with hot water above 80 °C can cause hydrolytic chain scission and reduce molecular weight; the grade is not intended for continuous steam service or hot-water pressure vessels. Storage should be in sealed, moisture-barrier bags. If the bag is opened in relative humidity above 60%, re-drying before processing is required. Re-drying above 90 °C should be avoided because plasticizer migration and pellet surface tack can occur.
For food-contact or potable-water applications, the base PA11 polymer is generally listed under FDA 21 CFR 177.1500 for certain nylon food-contact conditions, but this listing does not automatically cover all plasticizer packages. The exact BMNO P40 TLD grade must be confirmed with Arkema before use in food-contact tubing. Similarly, REACH substance-registration status and RoHS restricted-substance declarations under Directive 2011/65/EU require supplier confirmation for the specific commercial grade.
| Regulatory / standard reference | Scope | Verification required for BMNO P40 TLD |
|---|---|---|
| FDA 21 CFR 177.1500 | Nylon polymers for certain food-contact use | Supplier confirmation of plasticizer compatibility |
| Regulation (EC) No 1907/2006 | REACH registration and SVHC status | Grade-specific REACH statement |
| Directive 2011/65/EU | RoHS restricted substances | Supplier declaration for Pb, Hg, Cd, Cr⁶⁺, PBB, PBDE |
| SAE J844 | Air brake tubing | Burst, cold impact, zinc chloride resistance |
| ISO 7628 | Thermoplastic tubing for automotive use | Dimensional, burst, and low-temperature performance |
Lot acceptance for BMNO P40 TLD tube extrusion should include melt volume-flow rate according to ISO 1133-1:2022, moisture content, tensile stress at yield, elongation at break, and dimensional stability. For automotive pneumatic brake tube, the finished article is validated to SAE J844 or ISO 7628, including cold impact at −40 °C and burst pressure at ambient and elevated temperature. In fuel-vapor service, permeation rate, zinc chloride resistance, and sour-gasoline exposure are verified on the finished mono-layer or multi-layer wall. Where the tube is formed by in-line vacuum sizing, the calibration sleeve diameter must compensate for post-extrusion crystallinity-driven shrinkage; PA11 tube grades typically exhibit post-extrusion longitudinal shrinkage that stabilises after 24 h at ambient storage or after in-line annealing. Lot-specific data should be requested from Arkema, because the plasticizer package and moisture content influence low-temperature impact retention and burst behaviour.
