A conditioned, halogen-free PA12 compound with UL 94 V-0 performance at wall thicknesses down to 0.8 mm is applied in rail passenger rolling stock where flammability, smoke density and mechanical toughness are specified under EN 45545-2. The conformity assessment for interior cable ducts and junction boxes typically references EN 45545-2 Annex B test sequences using ISO 5659-2 smoke density Ds max and ISO 5660-1 cone calorimetry MARHE; the material is not a standalone approval but forms part of a classified component set. The compound is processed at 100 phr as supplied; if in-house regrind is returned from non-UV-exposed duct profiles, the addition ratio is limited to ≤ 15 wt% to maintain lot traceability and to prevent accumulation of heat history in the halogen-free flame-retardant system. No additional flame-retardant masterbatch is used because the grade is fully compounded. Dilution with unfilled PA12 is not recommended above 10 wt% without re-testing glow-wire behaviour at 960 °C on the final installed wall thickness. Single-screw extrusion of rectangular cable duct profiles uses a 25–30 L/D barrier screw, melt pump and vacuum calibration; melt temperature at the die is 235–245 °C, die-head pressure is typically 80–120 bar, and residual moisture after drying must be ≤ 0.08 % by ISO 15512. Post-extrusion dimensional control is maintained with water calibration at 25–30 °C and air gap adjustment before the vacuum tank. Terminal junction boxes, interior electrical enclosures, cable trunking and low-smoke conduit clips are the principal finished-part types in this application zone.
Within traction battery packs, cell-contact isolation plates, busbar support frames and longitudinal cell spacers are injection-molded from BADAMID PA12 FR HF natural R1 because the halogen-free FR package contributes to low smoke toxicity and the conditioned PA12 matrix retains impact resistance at sub-zero operating temperatures. Material acceptance commonly targets UL 94 V-0 at 0.8 mm, glow-wire flammability index GWFI 960 °C per IEC 60695-2-12 at 1.5 mm, glow-wire ignition temperature GWIT 775 °C per IEC 60695-2-13, comparative tracking index CTI ≥ 600 V per IEC 60112 and dielectric strength above 20 kV/mm per IEC 60243-1 after 48 h at 23 °C and 50 % RH. The addition level is 100 phr virgin compound; regrind from clean sprues and runners is limited to 10 wt% in battery safety parts because higher recycled fraction increases variability in flame performance after thermal ageing. Silicone-based internal mold release may be added at 0.1–0.2 wt% only if ejection force exceeds tool limits; external lubricants are avoided because they can contaminate subsequent bonding surfaces. Injection molding uses a 20–22 L/D general-purpose screw with compression ratio 2.0–2.2, barrel profile 240–250 °C, nozzle 245 °C, mold temperature 60–80 °C and hold pressure at 60–70 % of peak injection pressure. Residence time is kept below 4 min to prevent degradation of the flame-retardant package. Fan gates and edge gating are preferred for plate-like parts; weld-line positions must be shifted away from snap-fit or clip features by gate-location simulation. Finished parts include cell spacers, busbar holders, terminal isolation plates and internal cable guide rails.

UL 62275 and IEC 62275 govern cable ties for electrical installations; the halogen-free PA12 compound is used for releasable and fixed cable ties where fire performance and low smoke are required in switchgear, data centres and rail retrofit work. The compound is processed at 100 phr; regrind addition is limited to ≤ 20 wt% for general indoor ties and ≤ 10 wt% for releasable ties, because repeated heat history shifts moisture uptake and can alter pawl-locking behavior. Impact modifier addition is not recommended because it changes flexural modulus and reduces the number of reliable locking cycles; if softer actuation is required, the part geometry is adjusted rather than the formulation. High-cavitation tools with 24–64 cavities use cold-runner or insulated hot-runner systems; melt temperature is 240–250 °C, mold temperature 60–80 °C, and gate thickness at the strap edge is set at 60–70 % of strap thickness. Injection speed is kept high, with switchover at 0.5 s after filling onset? The hold-pressure profile is intentionally shortened to prevent sink on the ratchet surface. After ejection, parts are conditioned at 23 °C and 50 % RH for 48 h before loop tensile testing; dry-as-molded parts show brittle failure at the pawl. Finished types include panel cable ties, harness fasteners, releasable ties for control panels and data-centre cable management ties.
Miniature circuit breaker auxiliary contact carriers, coil bobbins and arc barrier plates are injection-molded from this grade in low-voltage switchgear where continuous-use temperatures do not exceed 90 °C. Compliance requirements include IEC 60695-2-11 glow-wire flammability at 850 °C on finished wall sections up to 1.0 mm, UL 94 V-0 at 0.8 mm, comparative tracking index CTI ≥ 600 V per IEC 60112 and dielectric withstand testing under IEC 60947-1. The formulation is used at 100 phr; regrind is limited to ≤ 20 wt%, and 0.2–0.3 wt% of a PTFE-free lubricant may be dry-blended only for thin-wall coil bobbins where ejection is problematic. Copper stearate and amine-based heat stabilizers are avoided because they can antagonize the halogen-free flame-retardant package and reduce UL 94 performance after thermal ageing. Insert molding over brass coil terminations requires preheating inserts to 110–120 °C; mold temperature is 70–80 °C, melt temperature is 240–250 °C, and wall thickness is held at ≥ 0.8 mm over long flow paths. Post-molding annealing at 120 °C for 2 h reduces molded-in stress around brass inserts and improves dimensional stability. Final products include auxiliary contact carriers, coil bobbins, arc barrier plates and DIN-rail mounting clips.
In IEC 61984 and IEC 60309 connector systems, halogen-free PA12 is used for insert bodies and cable glands because the material maintains tracking resistance after moist-heat conditioning and lowers smoke density relative to brominated flame-retardant copolymers. The grade is processed at 100 phr; regrind addition is limited to ≤ 15 wt%, and no flame-retardant masterbatch is used because the halogen-free formulation is fully compounded. If a black version is required, carbon black masterbatch addition is kept at 1–2 wt%, but natural R1 is preferred for non-pigmented or light-coloured connector bodies where laser marking contrast is specified. Insert molding over brass contacts and cable glands uses barrel temperatures of 240–250 °C, mold temperature 60–80 °C, preheated contact pins at 90–110 °C, and pack/hold pressure at 2–3 s/mm of nominal wall thickness. Creepage and clearance distances are verified under IEC 60664-1 after molding because shrinkage differences between insert and polymer can alter insulation coordination. Finished parts include 16 A and 32 A industrial plug inserts, angled cable glands, panel-mounted sockets and distribution-box cable entries.

AC charging plugs and in-cable control boxes require contact carriers that meet IEC 62196-2 for vehicle connectors and UL 2251 for North American EV charging equipment. In this application, the BADAMID PA12 FR HF natural R1 grade is processed at a melt temperature no higher than 250 °C; prolonged residence above 255 °C in hot-runner systems leads to surface deposit formation and loss of glow-wire ignition performance. Dry-blend addition is 100 phr compound; regrind from non-UV-exposed internal components may be added at ≤ 20 wt%, but outdoor load-bearing components require 100 % virgin compound unless the regrind is derived from identical outdoor-formulated lots. Natural R1 is not UV-stabilized; external charging components therefore require an additional UV additive package or a black version with validated weatherability. If UV masterbatch is incorporated, the let-down range is 1.5–2.5 wt% and the final part must be re-qualified for UL 94 V-0 at 0.8 mm. Sequential valve-gate injection molding uses a 35–40 mm screw, decompression 3–5 mm, mold temperature 70 °C and preheated contact pins at 120 °C. Gas-assisted molding is not compatible with the flame-retardant package. Post-molding moisture conditioning at 23 °C and 50 % RH for 48–72 h before installation restores snap-fit toughness. Finished types include Mode 2 and Mode 3 charging plug bodies, contact holders and internal supports for in-cable control boxes.
Busbar support insulators in server PDUs and rack power distribution units are injection-molded from this grade to meet UL 94 V-0 at 0.8 mm, glow-wire flammability at 960 °C at 1.5 mm, and comparative tracking index CTI ≥ 600 V for creepage requirements under IEC 62368-1. The compound is used at 100 phr; regrind is limited to ≤ 10 wt% for components nested near modular connectors because higher recycled fraction can introduce ionic contamination and reduce surface resistivity after damp-heat exposure. Release agents are avoided on surfaces that face live contacts; if demolding is critical, 0.1 wt% silicone-based internal release is the maximum permissible level. Injection molding in 8–16 cavity tools uses balanced cold-runner geometry, melt temperature 235–250 °C, mold temperature 50–70 °C and short hold time on thin ribs. Annealing at 120 °C for 2 h reduces post-molding warpage in long busbar support channels. The conditioned moisture state reduces dimensional drift in data halls maintained at 20–40 % RH. Finished parts include touch-proof terminal covers, busbar support frames, insulating bobbins and rack PDU internal barriers.

The injection moulding compound Bada BADAMID PA12 FR HF natural R1 PA12, Conditioned is a natural-coloured, unreinforced polyamide 12 based on a halogen-free flame-retardant system. The material is supplied in a conditioned moisture state, which is used for reporting mechanical values, and it is aimed at electrical and electronic housings, connector systems, cable management parts, and other components where low smoke density, low acid gas evolution, and high tracking resistance are specified. The designation FR HF identifies the halogen-free flame-retardant package, natural R1 identifies the natural, unreinforced colour position and the manufacturer’s internal formulation or rheology revision, and PA12, Conditioned describes the polyamide 12 base and the moisture-conditioned test condition. The conditioned state is not a surface treatment or a separate chemical grade; it is the condition in which specimens or mouldings have been brought to a defined moisture level, typically in a standard atmosphere at 23 °C and 50 % relative humidity according to ISO 291, or by accelerated conditioning according to ISO 1110.
Moisture uptake in polyamide 12 acts as a plasticiser. When the conditioned state is compared with the dry-as-moulded state, the tensile modulus and yield stress are lower, while the notched impact strength and fracture strain are higher. This shift is not a material defect; it is the expected response of the polyamide matrix to absorbed water. For halogen-free flame-retardant PA12 grades of this class, the conditioned equilibrium moisture content is generally below 1.0 wt%, and many polyamide 12 compounds stabilise in the range of 0.5 wt% to 0.8 wt% after storage at 23 °C and 50 % RH. Therefore, design data should always state the conditioning protocol. A modulus value determined on a dry specimen cannot be directly compared with a modulus value determined on a conditioned specimen because the difference may exceed 10 %, and the shift in notched Charpy impact can be substantially larger. The table below gives class-typical reference bands for conditioned halogen-free flame-retardant PA12 rather than certificate values for a single production lot.
| Property | Test method | Reference conditioned value |
|---|---|---|
| Density | ISO 1183-1 | 1.05–1.10 g/cm³ |
| Tensile modulus | ISO 527-1/-2 | 1600–2200 MPa |
| Yield stress | ISO 527-1/-2 | 38–52 MPa |
| Nominal strain at break | ISO 527-1/-2 | >20 % |
| Charpy notched impact, 23 °C | ISO 179-1/1eA | 8–15 kJ/m² |
| Charpy notched impact, −30 °C | ISO 179-1/1eA | 4–7 kJ/m² |
| Vicat softening temperature, B50 | ISO 306 | 135–155 °C |
| Comparative tracking index | IEC 60112 | 600 V |
| Volume resistivity | IEC 62631-3-1 | >1 × 1012 Ω·m |
| Dielectric strength | IEC 60243-1 | 28–34 kV/mm |
These reference bands are not a substitute for the manufacturer’s certificate of analysis. Published data for this specific configuration can be limited in open-access databases, and lot-specific flammability, rheology, and moisture content should be confirmed with the supplier. The R1 suffix can denote a specific viscosity level or recipe revision within the producer’s product family; where stamped part approval is required, the certificate and UL yellow card should be referenced.
Before any colouring, dilution, or compounding step is carried out, the moisture state of the product should be re-established. Although the material is supplied conditioned, it is not usually ready for melt processing without drying. Residual moisture above the melt-processing limit can hydrolyse the polyamide backbone, causing surface splay, silver streaks, reduced melt strength, and unstable mould filling. Desiccant drying at 80 °C for 4 h to 8 h to a residual moisture content below 0.10 wt% is a standard preparation for injection moulding. A drying hopper with a dew point of −30 °C or lower is recommended, and the dried granules should be protected from ambient moisture if machine residence time is short. The melt temperature for processing halogen-free flame-retardant PA12 should normally be controlled within 220 °C to 250 °C, with tool temperatures from 40 °C to 80 °C depending on wall thickness, surface appearance, and dimensional stability requirements.
Halogen-free flame-retardant packages based on phosphorus and nitrogen chemistry reduce thermal stability relative to unmodified polyamide 12. In production-scale injection moulding on single-screw reciprocating machines, the practical consequence is a narrower processing window. Melt temperatures above 240 °C should be limited to a residence time of approximately 10 min or less because extended heating can produce yellowing, surface deposits, and loss of flame-retardant performance at thin wall sections. Hot-runner systems should be designed for a thermally sensitive flame-retardant additive package. Gate diameters below 1.0 mm can raise shear heating and should be avoided in initial tool trials unless short flow lengths are required. Injection speed and hold pressure should be selected to avoid excessive shear, and back pressure should be kept low enough to prevent uncontrolled frictional heating. The use of a melt temperature 230 °C at the nozzle, with a rising temperature profile from the rear zone, is a reasonable starting condition for many natural-coloured PA12 FR HF compounds of this type.
For thin-wall electrical parts, mould filling is influenced by the higher melt viscosity of the flame-retardant system compared with neat PA12. Trial parts should therefore be sampled across the intended shot-weight range, and short-shot studies should be repeated after colouring because some pigments can shift flame-retardant performance. The natural R1 grade is intended for light-coloured or natural mouldings, but pigment addition can affect UL 94 performance. Any colour masterbatch should be verified for flame-retardant compatibility, and the final coloured part should be tested at the same wall thickness as the natural product.
Accelerated conditioning according to ISO 1110 is commonly performed on polyamide specimens using a defined time-temperature-humidity procedure to reach an equilibrium moisture level. In this state, the tensile modulus of the conditioned PA12 FR HF grade falls toward the lower end of the dry range, while Charpy notched impact rises. For snap-fit arms, integral hinges, and cable clamps, the conditioned state is often the worst case for stiffness and the best case for impact. For load-bearing structural deflection, dry-state data are conservative; for brittle failure, dry-state data are non-conservative. Finite-element material models should therefore include moisture-state-dependent modulus values. A single Young’s modulus without moisture context over-predicts flexural rigidity in humid service conditions.
Dimensional changes after exposing mouldings to 23 °C and 50 % RH are moderate in polyamide 12 because the base polymer absorbs less water than PA6 or PA66. For precision housings with tight gaps and snap fits, post-moulding dimensional checks should be performed after conditioning to the same moisture state as the end-use environment. The linear mould shrinkage of an unreinforced PA12 FR HF grade is typically low but not zero, and provision should be made for post-moulding moisture uptake. If post-moulding conditioning is accelerated, uncontrolled humidity can cause temporary surface condensation and a reduction in surface resistance before the part dries again.
For electrical applications, the conditioned state changes more than mechanical behaviour. Moisture reduces volume resistivity and dielectric strength relative to the dry state, although the halogen-free flame-retardant PA12 still retains insulating properties at ordinary low-voltage service conditions. Electrical insulation values reported on dry specimens cannot be transferred directly to a humid service environment. The relevant values should be generated on parts or specimens conditioned to ISO 291 or ISO 1110 and then tested under IEC 62631-3-1 for volume resistivity and IEC 60243-1 for dielectric strength. Comparative tracking index is reported according to IEC 60112 and is used within insulation coordination under IEC 60664-1. For this material class, halogen-free formulations often achieve a CTI of 600 V, which is advantageous for reduced creepage distances in compact electrical designs.
For low-voltage switchgear, terminal strips, connector housings, cable glands, and sensing device housings, the material is selected when flame retardancy, halogen-free combustion behaviour, low moisture absorption, and dimensional stability are required. The grade can be used in e-mobility charging infrastructure and photovoltaic junction boxes where glow-wire resistance is evaluated according to IEC 60695-2-11. Halogen-free flame-retardant PA12 generally produces lower acid gas evolution and lower smoke density than brominated flame-retardant alternatives when tested under fire-gas methods such as IEC 60754-1/-2 and ISO 5659-2. Published data for this specific configuration in prolonged outdoor UV exposure are limited; for external applications, a UV-stabilised black version or a supplementary coating may be required.
Unmodified PA12 has higher impact toughness and lower melt viscosity, but it is not inherently flame-retardant and normally carries a UL 94 HB classification. The halogen-free FR HF package in this grade increases stiffness, increases melt viscosity, and reduces unreinforced impact relative to standard PA12, while providing a wall-thickness-dependent V-0 classification. The natural R1 grade is unreinforced; therefore, it is not a direct substitute for glass-fibre-reinforced PA12 FR grades. Glass-filled grades provide higher flexural modulus, lower shrinkage, and better creep resistance, but they have lower unreinforced elongation and often lower track resistance.
In comparison with brominated flame-retardant PA12, the halogen-free system exchanges some flame-retardant efficiency for improved comparative tracking index, lower smoke density, and reduced acid gas emission during combustion. Brominated systems may achieve V-0 at lower addition levels and can have lower melt-pressure drop, but their combustion products require stricter ventilation and may corrode processing equipment. The halogen-free package based on phosphorus/nitrogen chemistry therefore fits applications where electrical tracking, smoke emission, and corrosion of adjacent components are design constraints. Against PA6 or PA66 halogen-free FR compounds, PA12 offers lower moisture absorption, lower density, and better dimensional stability in humid conditions, although the continuous-use temperature of polyamide 12 is generally lower than that of a suitably selected PA66 compound.

| REACH (EC) No 1907/2006 | SVHC screening | No intentionally added SVHC above 0.1 wt% |
Regulatory documents for the current production lot should be requested because flame-retardant chemistry can change under regional chemical inventories. Natural colour and halogen-free composition do not by themselves guarantee RoHS compliance; the complete formulation, including processing aids and stabilisers, must be declared. For electrical end equipment, the material is used within insulation coordination frameworks defined in IEC 60664-1, and the final part must be tested in its end-use wall thickness and colour. If metal contact compatibility is required, brass and silver-plated terminals should be tested under elevated temperature and humidity because electrochemical migration risk can increase in conditioned polyamide systems.
Cleaning of processing equipment between this halogen-free FR PA12 and other polymer families should include purging with a low-viscosity polyolefin or a dedicated purge compound. Residual flame-retardant packages can interact with PA66 or polyester in hot-runner manifolds, leading to black specks or contamination of transparent parts. Hot-runner nozzles and tips should be selected for thermally sensitive FR additive packages, and start-up purging at 240 °C should be limited to approximately 6 min before colour change is assessed. Moisture-conditioned material that has been opened and exposed to ambient air should be re-dried before processing if the storage time exceeds the producer’s stated limit.
