Arkema Rilsan BMV WHITE 5 P20 D PA11 is used as a one-part thermoplastic powder for corrosion-resistant linings on cast-iron valve bodies, pump casings, flanged pipe spools, and strainer housings in seawater, brackish water, and industrial process water service. The material is applied at 100% solids with no co-reactant, curing agent, accelerator, or primer; reclaimed overspray is limited to 30 wt% of the total charge to maintain melt-flow consistency and particle-size distribution. Metal preparation is performed to ISO 8501-1 Sa 2½ with an anchor profile of 75–110 µm Rz, because PA11 depends on mechanical keying rather than phosphate or chromate conversion layers. Preheat is controlled between 280 and 320 °C for wall thicknesses up to 12 mm; heavier castings are held at the upper bound and transferred to the spray booth within 30 s to limit surface-temperature fall below the melting band of 183–187 °C. Corona charging is set to 40–80 kV with a powder output of 80–150 g/min, while fluidizing air is maintained at 1.5–2.5 bar. After deposition, the parts are heated at 190–210 °C for 6–10 min to complete coalescence and crystallinity development. The finished lining thickness is held between 250 and 400 µm, with adhesion verified by ISO 2409 cross-cut or ISO 4624 pull-off testing. Neutral salt spray performance is assessed per ISO 9227 for 1000 h with scribe creep limited to 2 mm on production validation panels. End products include desalination-plant valve bodies, firewater pump casings, seawater strainer housings, and flanged pipe spools installed in coastal industrial facilities.
Copper busbars, switching contacts, and busbar trunking sections are insulated by fluidised-bed dip application of Rilsan BMV WHITE 5 P20 D PA11 in switchgear assembly lines. The powder is applied as a single-layer insulation system; no secondary topcoat is required, and the formulation is used as supplied without pigment letdown or solvent. Copper is degreased, blast-textured, and preheated to 240–280 °C, a narrower upper range than ferrous substrates because copper conducts heat rapidly and can develop hot edges. Dip time is 2–5 s; the part is then rotated to drain excess powder and baked at 190–200 °C for 5–8 min. The principal process conflict is edge coverage. Sharp rectangular busbar edges concentrate the electric field during subsequent dielectric testing, and the molten powder recedes from radii below 1.0 mm. Production-scale fluidised-bed lines processing PA11 powder have shown that thickness at a 0.5 mm edge radius can be 50–60% of the flat-face value; therefore the nominal face thickness is raised to 300 µm so that the edge remains above 150 µm. Compliance is assessed by IEC 60664-1 for clearances and creepage, IEC 60243-1 for dielectric strength, and IEC 62631-3-1 for volume resistivity. The end product is insulated busbar segments in motor-control centres and switchgear panels with service voltage ratings up to 1000 V AC or 1500 V DC.
| Application | Standard designation | Test condition | Required performance |

| Switchgear busbar insulation | IEC 60664-1:2020 | Clearance and creepage at pollution degree 2 | Rated impulse voltage dependent on system voltage |
| Switchgear busbar insulation | IEC 60243-1:2013 | Dielectric breakdown on flat panel | No breakdown below 20 kV/mm |
| Switchgear busbar insulation | IEC 62631-3-1:2016 | Volume resistivity at 23 °C and 50% RH | Above 1×1014 Ω·cm |
| Coating adhesion | ISO 2409:2020 | Cross-cut on metal substrate | Classification 0 or 1 |

Dishwasher rack wire forms are coated by fluidised-bed dipping in high-volume appliance-component plants. The material is charged into the fluidised bed at 100% virgin powder, with no external flow additive if the ambient relative humidity is held below 60%; above that threshold, the powder is pre-dried at 80 °C for 4 h to prevent steam porosity and film pinholes. A carbon-steel wire rack is degreased, shot-blasted, and preheated to 320–350 °C in an air-recirculating oven. The rack is then dipped for 3–6 s, withdrawn with slow rotation, and post-cured for 6–9 min at 190–210 °C. The melt viscosity of the PA11 grade permits a film thickness of 250–500 µm; at welded intersections, the thickness can reach 1.8–2.2× the nominal flat-wire value because of local mass accumulation during withdrawal. This local build-up is tolerated because it protects welded joints from detergent-induced crevice corrosion. The coated racks are tested in ISO 9227 neutral salt spray for 500 h and immersed in pH 10–11 detergent solutions at 70 °C for 1000 h to simulate appliance service. Compliance for the final component is normally reviewed against EU 10/2011 where incidental food-contact surfaces are possible, and against REACH 1907/2006 and RoHS 2011/65/EU for restricted substances. The end products are dishwasher baskets, cutlery trays, and oven-rack side frames used in domestic and commercial appliances.
Automotive fuel-line clips, sensor brackets, and wiring-harness brackets are coated with Rilsan BMV WHITE 5 P20 D PA11 where a dry, low-friction, non-embrittling layer is required. The powder is applied at 100% solids and reclaimed at a maximum of 20 wt%, because repeated high-velocity recycling reduces the sub-10 µm particle-size fraction and causes spitting from the spray gun. Steel or aluminium parts are preheated to 250–280 °C and sprayed with a film of 150–250 µm. Post-bake is 4–6 min at 190 °C. The coated parts are subjected to falling-weight impact at -40 °C per ASTM D2794 and stone-chip resistance per SAE J400. The principal operational boundary is that PA11 retains low-temperature flexibility without plasticizer, but it must not be combined with amine-based crosslinkers or epoxy curing agents because such additives interfere with molecular weight retention and film coalescence. Compliance for the final coated hardware is reviewed against RoHS 2011/65/EU and the relevant automotive OEM chemical-resistance specifications for engine-bay exposure. End products include fuel-line retention clips, brake-wear sensor brackets, and engine-compartment harness mounting brackets installed in passenger vehicles and light commercial trucks.

Cast-aluminium architectural lighting housings, HVAC condensate drip pans, and interior furniture fittings are coated with the white PA11 powder where the service environment is indoor or sheltered. The powder is sprayed directly onto blast-textured aluminium preheated to 250–280 °C. A single pass at 60–100 g/min and 50–70 kV deposits 120–180 µm in 2–3 s. The parts are then post-baked at 190 °C for 4–5 min. No primer is used, and the powder is applied as supplied without solvent, pigment letdown, or external plasticizer. For exterior architectural surfaces, PA11 is not exposed as the sole finish because unstabilised or lightly stabilised PA11 chalks under prolonged direct UV; a two-coat construction with an aliphatic polyurethane clearcoat is applied to exterior surfaces. The end products are indoor architectural light housings, furniture brackets, and HVAC drip pans requiring resistance to alkaline cleaning agents and standing deionised water. Published data for this specific white P20 D configuration under outdoor UV exposure is limited; therefore exterior qualification is conducted on a part-specific basis.
Small-bore steel and stainless steel tubing, pipe spools, handrail connectors, and hydraulic cylinder end caps are coated internally and externally by fluidised-bed immersion. The fluidised bed is operated at an air velocity of 2.5–4.0 cm/s through a porous plate of 40–70 µm nominal pore size, sufficient to maintain a homogeneous powder cloud without channeling. The powder is a single-component system, and the ratio of virgin to recovered powder is held at 70:30 by weight; higher recovered content produces intermittent spitting and uneven film thickness due to particle-size segregation and fines accumulation. Ferrous substrates are preheated to 300–330 °C and austenitic stainless steel to 270–300 °C, then dipped for 5–12 s depending on wall thickness. Post-cure is 5–8 min at 190–200 °C. Holiday detection is performed per ASTM D5162 to identify discontinuities in the lining, and adhesion is checked by ISO 2409. The end products are gas-distribution pipe fittings, handrail connectors, small-bore instrument tubing, and hydraulic cylinder end caps requiring resistance to salt water, mineral oils, and dilute alkaline cleaning solutions.

Arkema Rilsan BMV WHITE 5 P20 D PA11 is a specialty polyamide 11 grade within the Rilsan portfolio. The designation carries a white colourant package, a plasticised base, and a grade suffix that is not fully resolved in public documentation; lot-specific certificates of analysis are therefore the primary source for melt volume-flow rate, residual plasticiser content, and CIELAB colour coordinates. The base polymer is polymerised from 11-aminoundecanoic acid, a castor oil-derived monomer. The resulting 11-carbon repeat unit contains fewer amide groups per unit mass than PA6 or PA66, which lowers equilibrium moisture uptake and changes the balance of stiffness, low-temperature impact, and stress-cracking resistance.
Comparisons between this product and other nylons should be made on dry-as-moulded and conditioned specimens, because polyamide properties shift with moisture. The plasticised PA11 family is not a drop-in replacement for PA66 in rigid structural parts; its lower flexural modulus must be addressed in rib and wall-thickness design using ISO 178 and ISO 527-2 data. The grade occupies a position between unplasticised PA11 and highly flexible PA11 grades. The P20 plasticiser reduces tensile stiffness, increases elongation at break, and shifts the ductile-to-brittle transition to lower temperatures. These effects are measurable through ISO 527-2 and ISO 179-1/1eA; the exact shift for BMV WHITE 5 P20 D requires comparison with a natural, unplasticised control.
Because the product is white, it is often specified for parts requiring high opacity or colour-coded identification. However, white pigmentation is not a substitute for UV additives; outdoor exposure requires a UV-stabilised grade or additional screening. Weathering should be tested to ISO 4892-2 or ASTM G155 depending on the end-use specification. Rilsan PA11 base resin is derived from renewable castor oil. Renewable carbon content is determined by ASTM D6866 or ISO 16620-2; the white pigment and plasticiser reduce the renewable fraction of the final compound relative to the base polymer. A supplier certificate is required for biobased content claims.
Under ISO 62 conditioning at 23 °C and 50 % relative humidity, PA11 reaches an equilibrium moisture content of approximately 0.8–1.0 %, whereas unreinforced PA66 reaches 2.5–3.0 %. The difference arises from the lower amide-group density along the 11-carbon backbone. Moisture absorption plasticises the amorphous phase, lowers glass transition, and increases toughness while reducing modulus. Because PA11 absorbs less water, its dimensional change and stiffness shift under humid service are smaller than those of short-chain nylons. The lower moisture uptake is a function of chemistry, not a surface treatment. It remains effective when the part is machined or scratched, which is an advantage over surface-coated nylon parts.
The practical result is that PA11 components show less hygroscopic growth than PA66. Mechanical property data for PA66 are often reported at 23 °C and dry-as-moulded. If the part operates in humid air, the dry PA66 modulus can drop significantly after conditioning, while PA11 shows a smaller relative drop. This is why design comparisons should include ISO 1110 conditioned specimens, not only dry-as-moulded data. The following table compares typical property ranges for the Rilsan PA11 plasticised family, unreinforced PA12, and unreinforced PA66. The PA11 column represents typical Arkema Rilsan plasticised PA11 family ranges, not the exact BMV WHITE 5 P20 D lot.
| Property | Test designation | Rilsan PA11 plasticised family range | PA12 unreinforced range | PA66 unreinforced range |
|---|---|---|---|---|
| Density | ISO 1183-1 | 1.03–1.05 g/cm³ | 1.01–1.03 g/cm³ | 1.13–1.15 g/cm³ |
| Melting temperature | ISO 11357-3 | 186–190 °C | 175–180 °C | 260–265 °C |
| Water absorption, 24 h | ISO 62 | 0.3–0.5 % | 0.2–0.3 % | 1.5–2.0 % |
| Equilibrium moisture, 50 % R.H. | ISO 62 | 0.8–1.0 % | 0.7–0.9 % | 2.5–3.0 % |
| Tensile stress at yield | ISO 527-2/1A/50 | 25–35 MPa | 35–45 MPa | 80–90 MPa |
| Flexural modulus | ISO 178 | 800–1200 MPa | 1000–1400 MPa | 2800–3200 MPa |
Compared with PA12, PA11 has a higher melting point and higher renewable carbon content, but PA12 has lower density and lower saturated moisture uptake. The choice between PA11 and PA12 in flexible tubing is therefore driven by the upper service temperature, renewable-carbon requirements, and the specific fitting or welding process used. Published data for this exact configuration is limited; substitution from PA12 to BMV WHITE 5 P20 D requires burst-pressure, ageing, and dimensional stability tests. In zinc chloride stress-cracking exposure, PA11 generally outperforms PA66; tests under ASTM D543 or ISO 22088 use fixed-strain jigs and a defined reagent concentration. Grade-specific validation is required because pigment and plasticiser can shift stress-cracking resistance.
The first processing constraint for BMV WHITE 5 P20 D PA11 is residual moisture. Polyamide 11 undergoes hydrolytic chain scission during melt processing when granulate moisture exceeds 0.10–0.15 %. For white grades, hydrolysis appears as gas splay, die-lip deposit, and a yellow-to-brown shift in the pigment package. Closed-loop desiccant drying at a supply-air dew point of -40 °C or lower, 80–90 °C inlet temperature, and 4–6 h residence time is the standard pre-drying sequence for Rilsan PA11 extrusion grades. Drying of white pigmented PA11 must avoid air temperatures that can cause pellet sticking. At inlet temperatures above 90 °C, plasticised PA11 pellets may soften and bridge in the hopper. Therefore, the 80–90 °C window is both a hydrolysis control and a pellet-handling limit. Residual moisture should be measured by Karl Fischer titration to ISO 15512. Loss-on-drying indicators can be used for trend monitoring but may read high if low-molecular-weight plasticiser fractions volatilise.
For single-screw extrusion of plasticised PA11, a screw with L/D 24:1 to 30:1 and compression ratio of 2.5:1 to 3.5:1 is used. A representative barrel profile is 220–240 °C in the feed zone, 230–250 °C in the compression and metering zones, and 230–250 °C at the die. Melt temperature should not exceed 260 °C; white grades discolour under oxidative residence and plasticiser degradation shifts melt viscosity and odour. Barrel residence time should be kept below 5–8 min at melt temperatures near 250 °C for white grades. Longer residence time increases yellowness and may hydrolyse the polyamide if moisture is not fully removed. Screens of 60/80/100 mesh can be used; pressure upstream of the screen pack should be recorded for lot-to-lot comparison. A rapid pressure increase at constant screw speed suggests pigment agglomeration or contamination, not normal viscosity variation. Melt temperature should be measured by a thermocouple immersed in the melt stream, not only by barrel set-points. A melt-temperature difference of more than 10 K across the die can indicate shear heating in the screw or a partially blocked screen pack.
The P20 segment is consistent with plasticised Rilsan PA11 nomenclature, but exact plasticiser content is not publicly specified for this grade. Melt volume-flow rate should be measured to ISO 1133-1 at 235 °C and 2.16 kg. If lot-to-lot MVR differs by more than 15 %, the root cause should be identified before release. Capillary rheometry to ISO 11443 at 230 °C, 240 °C, and 250 °C is recommended when a new lot is introduced into a pressure-drop-limited tool. The TiO₂ pigment increases low-shear viscosity; the P20 plasticiser reduces it. The net effect is lot-dependent, so a single viscosity curve drawn from unplasticised PA11 should not be used for processing BMV WHITE 5 P20 D.
Injection moulding of the white plasticised grade uses melt temperatures of 240–260 °C and mould temperatures of 60–90 °C. Gates should be positioned so that weld lines do not fall on pressure-bearing surfaces; if weld-line strength is critical, ISO 527-2 opposed-gate tensile bars should be compared with single-gate specimens. A weld-line retention below 80 % of the single-gate tensile strength indicates a need for higher melt temperature, faster injection, or revised gate geometry. Venting is also critical because hydrolysis and pigment-degradation volatiles can produce gas burn marks. Vents should be maintained at 0.01–0.03 mm depth; deep vents may flash with low-viscosity plasticised melt. Regrind can be used only after drying and lot segregation. If regrind content exceeds 20 wt%, Charpy notched impact to ISO 179-1/1eA and tensile elongation to ISO 527-2 should be tested against virgin material. The white pigment may lose dispersion through multiple heat histories, which appears as surface blemishes and variable opacity.
Titanium dioxide and other white pigments are not inert viscosity modifiers. At loadings of 2–5 wt%, TiO₂ increases density and reduces weld-line tensile strength in unreinforced polyamides by disturbing chain diffusion across the weld plane. The white package can also shift mould shrinkage because pigment particles restrict flow orientation relaxation. Mould shrinkage should be measured under ISO 294-4. For plasticised PA11, flow-direction shrinkage is typically 0.8–1.2 % and transverse shrinkage is 1.0–1.4 %; tool compensation should be based on the actual lot because pigment loading and plasticiser content shift these values. Dimensional stability after ISO 1110 conditioning is better than PA66; the lower equilibrium moisture uptake limits hygroscopic growth.
CIELAB colour should be measured on dry granulate or compression-moulded plaques under D65 illumination and 10° observer. A b* shift above 2 units after processing indicates degradation or contamination. Opacity is affected by pigment dispersion; poor dispersion reduces hiding power and can create streak formation in thin-walled sections. Differential scanning calorimetry to ISO 11357-3 at 10 K/min shows the melting endotherm and crystallisation exotherm of the PA11 matrix. The enthalpy of fusion for the base resin is typically 80–100 J/g, but plasticisation and pigmentation reduce the measured crystalline fraction. A significant shift in melting peak or enthalpy between lots indicates variation in plasticiser content or crystalline thermal history.
Dynamic mechanical analysis to ISO 6721 is used to determine the glass transition. The plasticiser shifts the loss modulus peak to lower temperatures, which is the mechanism by which low-temperature flexibility is improved. Below the glass transition, the amorphous phase contributes greater stiffness, and the material may exhibit brittle failure under high strain rate. Therefore, Charpy notched impact testing to ISO 179-1/1eA should be performed at the lowest service temperature, not only at 23 °C.
The release and application testing framework for BMV WHITE 5 P20 D PA11 is not limited to a single property test. The following standards are relevant when the grade is used in tubing, connectors, or injection-moulded brackets.
| Standard or regulation | Scope | Relevance to grade release |
|---|---|---|
| ISO 1133-1 | Melt volume-flow rate | Lot-to-lot viscosity control |
| ISO 527-2 | Tensile properties | Bulk and weld-line strength |
| ISO 179-1/1eA | Charpy notched impact | Low-temperature toughness |
| ISO 7628 | Air brake tubing | Burst pressure, cold impact, dimensional stability |
| SAE J844 | Nonmetallic air brake tubing | Grade-specific automotive qualification |
| ISO 294-4 | Mould shrinkage | Tool compensation |
| ISO 6722 | Road vehicle cable | Abrasion and thermal ageing for cable jacketing |
| REACH EC 1907/2006 | SVHC declaration | Article 33 communication |
| RoHS 2011/65/EU Annex II | Restricted substances | Electrical and electronic components where applicable |
For applications requiring food-contact or medical clearance, the exact grade must be checked against the applicable positive list; the generic PA11 family does not automatically confer FDA 21 CFR or USP Class VI compliance. The BMV WHITE 5 P20 D designation does not, by itself, establish food-contact status. Air-brake tubing made from PA11 is subject to ISO 7628, which includes burst pressure at elevated temperature, dimensional stability, and low-temperature impact at -40 °C. SAE J844 is the North American equivalent for nonmetallic air brake tubing. BMV WHITE 5 P20 D would need to pass these tests as a finished tube; the raw material datasheet alone is not sufficient.
The chemical resistance of PA11 is a further differentiator. It resists hydrocarbons, oils, greases, and zinc chloride solutions; PA66 is more susceptible to zinc chloride stress cracking. Testing is performed under ASTM D543 or ISO 22088 using fixed-strain jigs and defined reagent concentrations. Because plasticiser extraction can occur in some aggressive media, immersion testing should include weight and tensile property retention after exposure. Fuel and chemical tubing made from PA11 are often tested to ISO 15105 for permeability or to SAE J2260 for fuel system applications. Because plasticiser can migrate into fuel, fuel extraction and permeation testing are required for plasticised grades. Published data for this specific configuration is limited; the grade should not be used in fuel-contact applications without complete validation.
Published data for this specific configuration is limited; material substitution from an established Rilsan PA11 grade to BMV WHITE 5 P20 D requires first-article qualification using the lot certificate and the applicable test matrix. Without such data, the grade should be treated as a plasticised, white PA11 with the generic processing constraints of the Rilsan PA11 family but no assumed equivalence to any other P20 designation.
