Injection moulding of 30 wt% carbon-fibre-reinforced heat-stabilised PA12 for automotive quick connectors and underhood line retainers is specified around a dry-before-melt principle rather than a single barrel temperature curve. The granulate is pre-dried in a desiccant dryer with a dew point of -40°C or lower at 80°C for 4 h to 6 h, targeting residual moisture below 0.10 wt% by Karl Fischer titration. Moisture levels above 0.15 wt% at melt temperatures between 245°C and 255°C cause hydrolytic chain scission, visible as surface splay, reduced burst pressure in the barbed section, and fluctuating melt viscosity during cavity transfer. A general-purpose screw with 20:1 to 24:1 L/D ratio and a bimetallic barrel is used because the carbon fibre phase accelerates screw, barrel, and check-ring wear; nitrided surfaces alone do not survive continuous production. Injection speed is kept in the medium band to preserve a continuous melt front through the thin retainer ring and prevent jetting. Holding pressure is profiled in two stages—an initial short peak to compact the carbon fibre domains and a lower second stage to avoid pin-gate blush. Mould temperature is held at 90°C to 100°C to produce sufficient crystallinity for creep resistance under thermal cycling from -40°C to 125°C per ISO 16750-4. Dimensional change at the connector seal interface is governed by the lower linear thermal expansion of the carbon-filled grade; any batch-to-batch shift in fibre length should be monitored against the supplier certificate because fibre attrition alters both flow-direction modulus and transverse shrinkage. Gate location is selected to avoid weld lines at the barb root and the retainer lip; the high carbon fibre fraction aligns along the flow front, and weld-line strength measured by ISO 179-1/1eA may fall below 60% of the unfilled matrix value when two fronts meet at low mould temperature. Cavity venting at the last-fill area is opened to 0.015 mm to 0.025 mm depth to prevent burn marks from compressed air, because carbon-filled melts generate higher viscous heating at the narrow seal ring. Dry-cycle monitoring includes injection pressure curves and cushion stability; a cushion of 2 mm to 3 mm is maintained to avoid fibre degradation in the screw tip. The material is accepted when moulded connector bodies pass leak, pull-off, and vibration tests described in SAE J2044 and SAE J1645.
The limitation is rarely short-term burst resistance; it is low-temperature impact after saturated fuel vapour exposure. A bracket moulded from 30 wt% carbon-fibre-reinforced heat-stabilised PA12 retains tighter bolt-preload flatness than unfilled PA12 because the carbon fibre reduces creep under clamp load. Continuous exposure ratings are governed by UL 746B relative thermal index or supplier-generated aging curves, not by a single melt point. In production, the material is dried to below 0.10 wt% moisture and processed at a melt temperature of 250°C to 265°C; the higher melt window is required to fill long boss and rib features, but residence time is capped at 8 min to avoid degradation of the heat stabiliser package. Mould temperature is set at 85°C to 95°C. The fibre orientation in the bracket base produces anisotropic shrinkage; the flow-direction shrinkage is lower than the cross-flow direction, and this must be compensated in the tool by separate scaling factors rather than a single linear allowance. Fastener bosses are designed with a minimum radius at the base to avoid stress concentration, because carbon fibre lowers notched impact strength compared with unfilled or impact-modified PA12. For CNG components, material lot testing includes density, ash content, tensile modulus by ISO 527-1/-2, notched Charpy impact by ISO 179-1/1eA, and dimensional change after immersion in fuel by ISO 175. Where the bracket is specified under ECE R110, the supplier must confirm that the specific heat-stabilised PA12 grade is approved under the relevant material annex; published data for this specific configuration is limited and component-level validation on the final bracket geometry remains mandatory.

Converting pneumatic valve manifolds from 30 wt% glass-fibre-reinforced nylon 6/6 to 30 wt% carbon-fibre-reinforced heat-stabilised PA12 is not primarily a cycle-time decision; the shift is made to reduce post-mould warpage caused by moisture uptake in compressed-air circuits. The PA12 backbone absorbs less equilibrium moisture than nylon 6/6, and the carbon fibre further constrains hygroscopic dimensional movement at port-to-port spacing. Multi-cavity manifold tools are run with sequential valve gates because the high thermal conductivity of carbon fibre leads to earlier gate freeze-off at the smaller pilot ports; a conventional cold runner with sub-gates produces cavity-to-cavity filling imbalance. Mould temperature is held at 80°C to 90°C, and melt temperature is kept between 240°C and 260°C to protect the heat stabiliser pack. Cavity pressure sensors are installed in the last-fill zone of each runner branch; cavity pressure at transfer is established from short-shot studies and is part-specific rather than a universal value. Venting depth at the end of fill is opened to 0.015 mm to 0.025 mm because carbon-filled melts compress residual air in the thread boss and produce local burn marks if venting is shallower. After moulding, the manifolds are pressure-tested per ISO 15407-1 and flow-tested according to ISO 6358. Chemical compatibility with compressor ester oils and water condensate is verified by immersion according to ISO 175. Strong acids, phenols, concentrated formic acid, and cresol-based cleaning agents are outside the chemical resistance envelope and must not be used in service or cleaning.
In chemical metering skids handling 30 vol% to 50 vol% ethylene glycol/water at 70°C, carbon-filled PA12 pump wear rings and impeller shims are specified for tighter running clearances than unfilled PA12. The carbon fibre loading reduces the coefficient of linear thermal expansion in the flow direction to roughly one-third to one-half of the unfilled PA12 value, which allows clearance reduction without seizure at elevated temperature. Tensile modulus is measured by ISO 527-1/-2; flexural creep is measured by ISO 899-2 at 80°C in the selected glycol mixture. Processing for pump components uses a dehumidifying dryer at 80°C for 6 h to 8 h and a melt temperature of 245°C to 270°C. The mould temperature is kept at 85°C to 100°C to promote crystallinity and reduce residual stress around the bore. Weld lines formed at the hub of an impeller are the limiting mechanical feature; the carbon fibre orientation at the weld line produces local strength below the bulk value, and gate position must be simulated with a fibre-orientation module before tooling release. Sharp transitions at the blade root are radiused sufficiently to avoid notch-dominated failure, because carbon fibre reduces notched impact strength compared with unfilled PA12. For slurry contents above 10 vol% or particle sizes above 100 µm, the wear rate of carbon-filled PA12 exceeds that of hardened alloy or ceramic-coated alternatives, and the component must be treated as sacrificial. The run-out on the pump shaft should be checked with a dial indicator at assembly; carbon-filled PA12 is less tolerant of shaft run-out than softer unfilled PA12 because the higher modulus transmits bearing loads to the hub. Published data for this specific grade in a close-running wear ring geometry is limited; a bench wear test under the actual glycol mixture is required before release.
The use of carbon-filled PA12 in ESD-sensitive sensor housings is governed by surface resistivity control after prolonged exposure to mineral oil and condensation, not merely by as-moulded conductivity. A 30 wt% carbon-fibre loading typically places surface resistivity in the 10³ Ω/sq to 10⁶ Ω/sq range when measured according to ASTM D257; this is within the dissipative range accepted by IEC 61340-5-1 and ANSI/ESD S20.20. The housing must be tested after conditioning in the intended hydrocarbon medium because an oil film may create a superficial insulating layer that raises the apparent surface resistivity until the surface is wiped. Moulding parameters are selected to maintain fibre distribution at the surface; a too-low injection speed allows a resin-rich skin to form, which shifts resistivity upward, while a too-high screw speed creates fibre breakage that reduces conductivity and increases resistivity. Mould temperature is held at 70°C to 90°C; lower temperatures produce a glossy but resin-rich surface that is not representative of the bulk conductive network. Cleaning with isopropanol or naphtha is acceptable, but alkaline cleaners above pH 10 can attack the PA12 matrix and should be avoided. For applications requiring electromagnetic shielding rather than simple static dissipation, this compound is not a substitute for metal-coated or intrinsically conductive polymer systems above roughly 60 MHz; measured shielding effectiveness data for this grade is not supplied.
Tooling for heated urea or coolant distribution manifolds in 30 wt% carbon-fibre-reinforced PA12 must be designed around the mechanism of gate freeze-off rather than a generic shrinkage allowance. Carbon fibre increases the thermal conductivity of the melt, so gates solidify faster than in unfilled PA12 at the same melt temperature. The gate diameter is therefore not reduced below the local wall thickness at the boss; a gate below 1.5 mm on a 3 mm wall manifold frequently seals before the holding pressure can compensate for the high fibre packing density, leaving internal porosity at the junction. Sequential valve gates are used on long manifolds to maintain a stable fibre orientation vector and prevent shifting knit lines at the distribution branches. Melt temperature is controlled between 250°C and 265°C; mould temperature is set at 90°C to 105°C to maximize crystallinity and reduce warpage after hot assembly. Drying follows the same 80°C for 6 h protocol with a dew point of -40°C or lower. For diesel exhaust fluid circuits, the material is acceptable below 60°C continuous exposure; operation above 80°C in highly alkaline DEF requires validation because the carbon fibre sizing and heat stabiliser may be extracted at the surface. Flatness after clamping is checked against the part drawing with a feeler gauge on a granite plate; no visible fibre accumulation at the gate should be accepted because local fibre packing creates a hard spot that resists the sealing bead.

LATI Latamid 12 H2 K/30 is a heat-stabilised polyamide 12 injection moulding compound containing a nominal 30% by mass carbon fibre reinforcement. The material is designated under ISO 1043-1 as PA12 CF30 heat-stabilised. In LATI nomenclature, Latamid 12 identifies the base polyamide, H2 identifies the heat-stabilisation package, K identifies carbon fibre reinforcement, and /30 defines the filler weight fraction. The base polymer is polylaurolactam, a semicrystalline polyamide with lower equilibrium moisture uptake than PA6 or PA66 and a melting temperature near 175–180 °C according to ISO 11357-3 differential scanning calorimetry. The carbon fibre phase raises tensile modulus and creep resistance, lowers density relative to glass-filled PA12, and creates measurable electrical conductivity. The heat-stabiliser package slows oxidative ageing at elevated service temperatures, but it does not elevate the continuous-use limit beyond the inherent thermal-oxidative boundary of the PA12 matrix. The grade is supplied as black pellets; colour variation is constrained by carbon fibre pigmentation. Applications are therefore concentrated in dimensionally stable, electrostatically dissipative, or stiffness-driven structural parts where low moisture uptake and low density are required. The compound is not an unfilled PA12, not a glass-fibre PA12, and not an inherently high-temperature polyamide; design teams must account for material anisotropy, moisture-conditioned property shifts, and the electrically dissipative surface behaviour before substituting it into a metal or glass-filled part.
Moisture control is the first processing constraint. The granulate should be dried in a desiccant dryer with a dew point below -30 °C, using drying air temperature between 75 °C and 85 °C. Residual moisture before melt processing must be below 0.10% by mass, measured by Karl Fischer titration in accordance with ISO 15512. If material has been exposed to relative humidity above 60% or stored in cold conditions, drying time is commonly extended to 8–12 h. Undried material hydrolyses the PA12 chain during plastication, reducing molecular weight, increasing melt-flow rate, and shifting notched impact performance downward. On injection moulding machines with screw diameters from 25 mm to 40 mm, filled PA12 is processed with rear zone temperature near 220–240 °C, centre zone temperature near 240–260 °C, front zone temperature near 250–270 °C, and nozzle temperature near 250–270 °C. Melt temperature measured at the nozzle should remain between 240 °C and 270 °C. Mould temperature should be controlled from 70 °C to 90 °C for semi-crystalline solidification; lower mould temperatures reduce crystallinity and worsen long-term dimensional stability, while higher mould temperatures increase cycle time without proportional property benefit.
Screw geometry has a direct effect on fibre length retention. A low-compression screw with compression ratio between 2.0:1 and 2.5:1, length-to-diameter ratio from 20:1 to 25:1, and a non-return valve with generous flow channels limits fibre attrition. Back pressure should remain between 20 bar and 50 bar. Screw speed on a 30 mm screw should not exceed 100 min⁻¹ in continuous production. Residence time at maximum melt temperature should be kept below 6 min to prevent consumption of the heat stabiliser and thermal degradation of the carbon fibre sizing. Production-scale trials on filled PA12 have shown that aggressive screw speed, narrow hot-runner channels, or pin-point gates below 1.5 mm diameter reduce median fibre length from pellet values of 250–350 µm to moulded-part values below 150 µm. The resulting loss in tensile modulus can reach 5–15% relative to a properly processed part. Weld lines are a known process boundary: carbon fibre orientation parallel to the weld line plane can reduce weld-line tensile strength to less than 50% of the unwelded ISO 527-1/-2 tensile value. Gate location, wall thickness, and flow-channel balance therefore determine whether the part can meet structural requirements.
Compounding is similarly shear-sensitive. The material is typically produced on twin-screw extruders with length-to-diameter ratio between 32:1 and 40:1, with carbon fibre introduced downstream after the polymer melting zone to limit excessive fibre breakage. Vacuum devolatilisation at approximately -0.08 MPa removes volatile residues and residual moisture. If the compound is later reprocessed through regrind addition, fibre length falls further, and regrind levels above 15–20% may alter flow-direction tensile modulus and notched impact. Every lot should therefore be handled with documented regrind content and melt-flow-rate verification in accordance with ISO 1133-1:2022.
Representative lot-specific data for Latamid 12 H2 K/30 must be taken from the manufacturer certificate of analysis. Published data for this specific configuration is limited where exact processing conditions, regrind content, and specimen moulding history differ from the customer process. Without lot-specific verification, design calculations should use minimum rather than typical values, and prototype tools should be sampled with the same gate geometry and fibre-orientation pattern as production tooling.
Carbon fibre reinforced PA12 at 30% loading is typically supplied with density in the range of 1.15–1.20 g/cm³ when conditioned to ISO 1183-1. The tensile modulus, measured dry-as-moulded according to ISO 527-1/-2 on injection-moulded specimens, is generally reported between 15,000 MPa and 19,000 MPa. Tensile strength at break under the same protocol is reported between 150 MPa and 180 MPa, with elongation at break below 3.0%. Flexural modulus measured by ISO 178 can fall between 13,000 MPa and 17,000 MPa, depending on fibre orientation through thickness. Charpy notched impact strength under ISO 179-1/1eA is typically in the range of 5.0–8.0 kJ/m². The heat-deflection temperature at 1.8 MPa using ISO 75-1/-2 is typically between 150 °C and 165 °C, but this value is sensitive to specimen thickness, fibre orientation, and conditioning history. The coefficient of linear thermal expansion parallel to flow under ISO 11359-2 is commonly between 15 × 10⁻⁶ K⁻¹ and 25 × 10⁻⁶ K⁻¹; transverse values are higher and must be accounted for in assemblies with metallic inserts.
| Property | Test Method | Typical Range for Latamid 12 H2 K/30 | Unit |
|---|---|---|---|
| Density | ISO 1183-1 | 1.15–1.20 | g/cm³ |
| Tensile modulus | ISO 527-1/-2 | 15,000–19,000 | MPa |
| Tensile strength at break | ISO 527-1/-2 | 150–180 | MPa |

The table is not a substitute for the certificate of analysis. The values shift after moisture conditioning to ISO 1110, after long-term heat ageing, or in moulded regions with transverse fibre orientation. Moulded specimens prepared according to ISO 294-1 and ISO 294-2 exhibit different values from plaques cut from production parts, particularly at weld lines, ribs, and gate areas. For load-bearing design, the anisotropy ratio between flow and transverse tensile modulus should be evaluated experimentally on the actual part geometry, because published data for this specific configuration is limited to standard specimen geometries.
The principal difference between Latamid 12 H2 K/30 and a 30% glass-fibre reinforced heat-stabilised PA12 is the increase in tensile modulus combined with lower density and the emergence of electrical conductivity. Glass-fibre reinforced PA12 at comparable filler content commonly reports tensile modulus between 7,500 MPa and 9,500 MPa, while carbon fibre increases stiffness into the 15,000–19,000 MPa range. Density falls from approximately 1.24–1.28 g/cm³ for 30% glass fibre to 1.15–1.20 g/cm³ for 30% carbon fibre. The result is a substantial improvement in specific stiffness, measured as tensile modulus divided by density. This comparison is relevant when lightweight structural parts must replace metal stampings or die-cast aluminium.
Notched impact strength is usually lower in carbon fibre PA12 than in glass fibre PA12. Glass fibres can provide Charpy notched impact performance above 8.0 kJ/m², while carbon fibre grades typically remain below 8.0 kJ/m². In applications with snap-fit arms, threaded inserts, or sharp internal radii, this difference is process-critical. The carbon fibre grade also creates higher tool wear in gates, runner blocks, and screw tips because of the abrasive nature of carbon fibre. Nozzle tips and check rings should be specified with wear-resistant coatings or hardened tool steels.
Against a 30% carbon fibre reinforced PA66, the PA12-based product displays lower moisture absorption, better dimensional stability in humid air, and lower density. PA66 CF30 typically absorbs more water and can shift mechanical properties more strongly between dry-as-moulded and conditioned states. However, PA66 CF30 generally retains higher heat-deflection temperature and better creep resistance at temperatures above 130–150 °C. Latamid 12 H2 K/30 is therefore selected when the part is exposed to changing humidity and only moderate elevated temperature, while PA66 CF30 is selected when high-temperature creep dominates. Against unfilled heat-stabilised PA12, the carbon fibre grade raises tensile modulus by roughly an order of magnitude and reduces moulding shrinkage, but it sacrifices ductility and increases anisotropy.
Surface appearance also differs. Glass-filled PA12 can be coloured and can yield lighter surfaces, while carbon fibre PA12 is limited to black or dark grey and can show visible fibre orientation patterns. The surface can be textured to mask flow lines, but painting and plating adhesion are not guaranteed without surface treatment. Dimensional tolerances are governed by ISO 294-4; carbon fibre PA12 typically exhibits lower moulding shrinkage in the flow direction but can exhibit higher transverse shrinkage than glass-filled PA12. The difference is caused by fibre orientation and must be corrected in tool design.
At 30% carbon fibre loading, the compound normally lies above the percolation threshold for electrical conductivity. Dry-as-moulded surface resistivity measured with a concentric ring probe in accordance with IEC 62631-3-2 commonly falls between 10³ Ω and 10⁶ Ω. This range is sufficient for static dissipation in many automation and electronics handling applications, but it does not automatically provide electromagnetic interference shielding above 20 dB. Shielding effectiveness must be measured according to ASTM D4935 or IEC 62333-1 on the actual part geometry. Volume resistivity under IEC 62631-3-1 is generally higher than surface resistivity and is strongly influenced by fibre orientation, skin-core morphology, and moisture. Carbon fibre PA12 should not be treated as a metal substitute for grounding unless the equipment grounding path is verified under EN 61340-4-1 for personnel safety systems.
Thermal conductivity also increases with carbon fibre content. Unfilled PA12 has thermal conductivity near 0.2–0.3 W/(m·K). Carbon fibre reinforced PA12 can exhibit through-plane thermal conductivity in the range of 0.5–1.0 W/(m·K), with higher in-plane values because of fibre orientation. Measurement should follow ISO 22007-2 or ASTM E1461 for lot-to-lot verification. This property is useful in housings that must dissipate heat from embedded electronics, but the material remains thermally insulating compared with metals and ceramics. It is not a thermal-interface material.
Dimensional stability is governed by moisture absorption, thermal expansion, and anisotropic moulding shrinkage. PA12 absorbs less water than PA6 or PA66, but it is not hydrophobic. Moisture uptake modifies dimensions and lowers the glass transition temperature. Carbon fibre reduces the absolute magnitude of moisture expansion but does not eliminate it. Parts dimensioned to tight tolerances should be conditioned to the expected service humidity before final inspection. Unconditioned parts machined immediately after moulding may pass initial metrology but shift after exposure to humid air. Dimensional verification should therefore be performed after conditioning to ISO 1110 or to the specific application environment.
Moulding shrinkage in the flow direction for 30% carbon fibre PA12 is commonly in the range of 0.05–0.20%, while transverse shrinkage can reach 0.30–0.60%. These values are dependent on wall thickness, gate geometry, packing pressure, and fibre length. Post-moulding annealing at 120 °C for 2 h can relieve frozen-in orientation and improve dimensional stability, but it can also cause minor additional shrinkage and property relaxation. Annealing must therefore be planned before final tolerance evaluation. If the part contains metal inserts, differential thermal expansion can lead to hoop stress or insert pull-out; calculation should use the anisotropic coefficient of linear thermal expansion rather than a single isotropic value.
Structural applications for Latamid 12 H2 K/30 are typically stiffness-driven and weight-sensitive. Candidate geometries include automation end-effector brackets, robot arm covers, pneumatic actuator housings, pump impellers, gear housings, and electronic enclosure frames. In continuous load, creep resistance under ISO 899-1 should be measured at the service temperature and stress level. Published data for this specific configuration is limited for long-term creep and fatigue, so part qualification should include notched fatigue on weld lines and stress concentrations. For cyclic loading, carbon fibre PA12 may show a fatigue knee at 10⁶ cycles near 60–80 MPa in dry-as-moulded condition, but this value is not a universal design allowables. Humid ageing can lower fatigue strength by 10–20%, and weld lines can lower it further.
Sliding wear is a boundary condition. Carbon fibre reduces wear factor against steel in some tribological contacts, but the exposed carbon fibre can abrade softer counterfaces. If the part is to run against aluminium or bronze, pin-on-disc testing under ISO 7148-2 is required. If low friction is required, graphite or PTFE modification may be necessary; Latamid 12 H2 K/30 is not specified as a tribological grade unless the manufacturer lot card explicitly confirms such modification. Applications with continuous sliding contact should not proceed on the basis of generic carbon fibre wear claims.
Compliance must be verified against the specific lot and the specific grade. The compound may be subject to EU RoHS Directive 2011/65/EU Annex II for electrical and electronic equipment, and REACH Regulation 1907/2006 for substances of very high concern under Article 33. A RoHS compliance declaration does not automatically establish REACH compliance, and a raw-material statement is not a substitute for the finished-article obligation. Electrical surface resistivity should be verified according to IEC 62631-3-2, while electrostatic discharge control in production environments should follow IEC 61340-2-3. Melt mass-flow rate or melt volume-flow rate is reported under ISO 1133-1:2022 at the manufacturer-specified temperature and load; filled PA12 grades are generally tested at 235 °C or 275 °C with a 2.16 kg or 5 kg load, but the lot certificate must state the exact condition.
| Document or Regulation | Parameter Verified | Typical Scope for This Grade |
|---|---|---|
| EU RoHS 2011/65/EU | Lead, mercury, cadmium, hexavalent chromium, PBB, PBDE | Electrical and electronic equipment if applicable |
| REACH 1907/2006 | SVHC notification under Article 33 | Lot-specific declaration required |

Material traceability should be maintained by lot number through drying, moulding, regrind addition, and post-moulding operations. For safety-relevant parts, documentation should additionally include the lot-specific tensile modulus, density, moisture content, and surface resistivity. The manufacturer certificate is not a design substitute; it is a conformity document. Finished-part tests under the actual production mould, gate configuration, and conditioning protocol remain the only valid basis for release of dimensionally stable, electrically dissipative, or structurally loaded components.
