Обзор продукта и ключевые особенности
PA6 ETF02 is a high-temperature heat-age-stabilized engineering plastic compound produced by Juhai Plastics using a premium PA6 base resin reinforced with 30% high-quality silane-sized chopped E-glass fibers and compounded on our co-rotating twin-screw extrusion line with a proprietary dual-package heat stabilizer: Copper(I) Iodide / Potassium Iodide (CuI/KI) halide salt plus an aromatic diamine secondary anti-oxidant. The two stabilizer chemistries work synergistically — the CuI/KI chelates thermally generated amide free-radical chain ends while the aromatic amine AO quenches peroxide decomposition — giving PA6 ETF02 roughly 4–5× the long-term thermal life of an unstabilized PA6 GF30 in the critical 120–160°C automotive and industrial operating window.
Основные эксплуатационные преимущества
- Class-Leading Long-Term Heat Aging Retention: After 3 000 hours of continuous forced-air aging at 150°C, tensile strength stays above 80% of the unaged value and elongation at break above 55%. Unstabilized PA6 GF30 drops below 40% tensile and becomes brittle under the same conditions.
- High HDT and Vicat for Peak Loads: Heat Deflection Temperature reaches 210°C at 0.45 MPa and 188°C at 1.82 MPa, with Vicat softening at 207°C. Short-duration peak temperatures of 175°C are tolerated without structural failure.
- 30% Glass Fiber for Structural Rigidity: 152 MPa tensile strength and 7 300 MPa flexural modulus provide the stiffness required for headlamp reflector alignment, engine bay air-box geometry retention, and motor end bracket bearing-bore concentricity under load and heat.
- Non-Staining Copper Stabilizer Package: Inhibited CuI/KI complex passes IEC 60426 contact-corrosion tests against bare copper, brass, tin and aluminum with less than 0.3 mg/cm² metal loss — no green-oxide staining on lamp heat sinks or motor commutator contacts.
- Carbon-Black Synergist (Standard Color): 2.0% carbon black pigment acts as both a UV absorber (for headlamp clear-lens outdoor exposure) and a surface free-radical quencher that modestly extends heat-aging retention by 5–7% versus natural-color variants.
- CTI ≥ 500 V for Electric Motor Use: Comparative Tracking Index of ≥500 V (PLC 1) satisfies the creepage-and-clearance requirements for molded commutator end brackets mounted directly above insulated armature windings.

Контроль качества и методология производственных испытаний
Every lot of PA6 ETF02 passes through our ISO 9001 stage-gate quality process before release. Because the heat-aging retention performance is the critical differentiator of this Premium-tier grade, we perform real 150°C accelerated aging tests on every production batch — not just on a periodic-type basis. This is one reason PA6 ETF02 carries a slight price premium over a Standard-tier PA6 GF30 grade.

Параметры инжекционного формования
PA6 ETF02 has specific residence-time and temperature limits because the CuI halide component can catalyze PA6 amide-bond hydrolysis or chain scission if held above 280°C for extended periods. Observe the settings below and install a barrel-residence timer alarm on the molding machine for parts with long cycle times.
| Process Parameter | Recommended Range | Notes / Limits |
|---|---|---|
| Pre-Drying (MANDATORY) | 80 °C × 4 hours; dehumidifying dryer to < 0.08% moisture | Ambient air drying not acceptable. Use -40°C dew-point dryer. Moisture >0.15% causes splay AND accelerates in-barrel hydrolysis. |
| Barrel Temp — Rear / Middle / Front | 240 °C / 255 °C / 268 °C | Gradual profile; avoid front-zone spikes above 275°C. |
| Nozzle Temperature | 265 - 272 °C | Slightly lower than front zone to prevent drooling. Never exceed 275°C at nozzle. |
| Maximum Barrel Residence Time | < 6 minutes at ≤ 275 °C; < 3 minutes if any zone hits 280 °C | CRITICAL. Long residence + high temp → CuI catalyzed chain scission → loss of impact and heat-retention properties. Set screw recovery delay and shot-size accordingly. |
| Mold Temperature | 70 - 95 °C | 85°C+ recommended for Class-A lamp-housing surface and optimal GF wet-out. |
| Injection Pressure | 85 - 135 MPa | Thin lamp ribs and end-bracket bosses may need the upper end. |
| Holding Pressure | 55 - 75% of injection pressure | Holding time: 12-28 s depending on wall thickness. |
| Screw Back-Pressure | 4 - 8 bar | Moderate back-pressure; avoid >10 bar to reduce shear heating and residence. |
| Screw Speed (RPM) | 70 - 130 rpm | Moderate speed minimizes shear-heat spike and fiber attrition. |
| Screw / Barrel Material | Through-hardened tool steel (HRC 55+) or bimetallic barrel | CuI/KI is mildly abrasive to nitrided barrels over 10 000+ hours; chrome plating alone is not sufficient. |
| Purge Between Material Changes | Natural unfilled PA6 or commercial PP-based purge compound | Do NOT purge ETF02 with unfilled PP or PE directly, as residual CuI may contaminate the next clear/transparent resin run. |
Хранение и срок годности
- Store in original sealed bags below 35°C and below 70% relative humidity.
- Keep away from direct sunlight and sources of heat or open flame.
- Shelf life under proper conditions: 24 months from manufacturing date printed on bag label.
- Once opened, use contents within 3 weeks or re-seal with desiccant packs to prevent pre-moisture pickup.
- Do not mix ETF02 pellets with unstabilized PA6 GF grades in the same gaylord or dryer hopper — even 5% of an unstabilized grade can lower the overall heat-retention curve below spec.
Руководство по устранению неисправностей при инжекционном формовании
Because PA6 ETF02 contains both a 30% glass-fiber load and the sensitive CuI/KI halide heat-stabilizer package, certain defect modes appear more frequently than with a standard unfilled or unstabilized PA6. Use the table below as a first-pass troubleshooting reference; for persistent issues, send us a photo of the defect, your machine barrel-temperature log, and the current MVR of your regrind fraction — our process engineers will respond with a specific corrective-action sheet within one working day.
| Defect / Symptom | Most Likely Root Cause(s) | Step-by-Step Corrective Action |
|---|---|---|
| Splay marks (silver streaks) on the gate side or along rib bases | 1) Insufficient pre-drying, residual moisture > 0.08%; 2) Too-rapid injection speed through small gate; 3) Leaking non-return valve causing backflow and moisture steaming. | Step 1: Re-measure granule moisture with Karl Fischer immediately at machine throat. If >0.08%: extend dryer time 2 more hours at 85°C, confirm dew-point at dryer outlet ≤ -40°C. Step 2: Drop injection speed by 20% in the first stage, increase by 5% only after splay disappears. Step 3: Purge and inspect check ring / non-return valve for wear (gap > 0.1 mm → replace). Step 4: If using regrind, cap regrind fraction at ≤ 20% and dry regrind separately before blending back — regrind picks up 2–3× moisture from ambient. |
| Brittle part edges or unexpectedly low notched Izod on molded parts | 1) CuI-catalyzed chain scission from too-long barrel residence at high temp; 2) GF fiber attrition from excessive screw speed or >10 bar back-pressure; 3) Degraded regrind (recycled many times at too-hot profile). | Step 1: Calculate barrel residence = (barrel capacity cm³ × melt density 1.07 g/cm³) ÷ shot weight g × cycle time s. Must be < 360 s at ≤ 275°C; if over, reduce shot size by increasing cushion or moving to smaller machine. Step 2: Drop front/nozzle temp 5°C each step, verify residence alarm set. Step 3: Reduce screw RPM to 80, drop back-pressure to 4–5 bar. Step 4: If using >20% regrind, send regrind sample for MVR vs pellet MVR — ΔMVR > +15 points = chain degraded; discard regrind lot. |
| Float marks / glass-fiber read-through on Class A lamp housing surface | 1) Mold temperature too low (< 75°C); 2) Holding pressure too low or hold time insufficient for wall thickness; 3) Poor gate land size causing freeze-off before skin layer can smooth. | Step 1: Raise mold to 85–90°C using a pressurized water or oil temperature controller — this is the single largest lever for ETF02 surface. Step 2: Increase hold pressure to 70–80% of injection peak; add 3–5 s hold time per mm of nominal wall. Step 3: If runner/allowing, polish gate land 5–10 mm and confirm gate depth ≥ 0.8 mm for GF material. Step 4: For hot-runner systems, drop manifold temp 10°C to reduce premature freeze before skin packs. |
| Warpage on flat end-bracket flange or lamp reflector back-plate | 1) Asymmetric shrinkage from unbalanced mold temperature (stationary vs moving side delta > 10°C); 2) Holding pressure switched off too early before gate freeze; 3) Glass-fiber orientation imbalance due to single-gate flow pattern on large part. | Step 1: Verify moving-half and fixed-half mold circuits individually — set both to 85°C ± 2°C (use separate temp-control units, no series loop). Step 2: Extend hold time by 5 s; confirm by short-shot study that gate does not freeze at cutoff. Step 3: For parts > 200 mm across, review gating with our engineer. Fan gate or diaphragm gate often eliminates warpage on round reflector-back / end-bracket parts. Step 4: Slight shrinkage compensation in tool steel (0.33% flow, 0.92% cross) must be applied uniformly. |
| Brown / amber discoloration streaks in nozzle area or at last-fill | 1) Dead spots in barrel / nozzle tip holding material at high temp > 8 min; 2) Material hang-up at cracked torpedo or bimetallic barrel liner gap; 3) Excessive front zone temp > 278°C combined with long cycle. | Step 1: Drop front zone and nozzle temp to 260°C, purge 10 full shots of natural PA6. Step 2: Inspect nozzle tip / nozzle body for coked material buildup — soak in PE purge overnight if needed. Step 3: Pull screw and inspect flights, check ring, and torpedo for wear grooves or polymer degradation if discoloration continues after purge. Step 4: Install screw-idle timer that retracts screw and lowers rear-zone temp 10°C during downtime > 2 min. |
| Dimensional shift on bearing bore / reflector alignment feature after 120°C post-mold annealing | 1) Residual molded-in stress released at temperature; 2) Wall thickness imbalance causing non-uniform GF orientation; 3) Under-packed section with incomplete skin consolidation. | Step 1: Verify post-mold annealing cycle (if used) — heat up slowly at 0.5°C/min to 110°C, hold 2h per mm of max wall, cool slowly. Step 2: Increase pack/hold phase pressure by 10%; extend hold to ensure gate does not freeze before packing peak. Step 3: If feature is near weld line, move or add venting; confirm weld-line strength by testing. Step 4: For precision bearing-bore applications, prototype with ETF02 at the final tool geometry using your production molding parameters — dimensional data at heat is available from our application lab for common bracket geometries. |
| Nozzle drooling between shots causing gate vestige or stringing | 1) Nozzle temp 3–5°C too high vs front zone; 2) Decompression / suck-back distance insufficient or too fast; 3) MVR at upper end of 30–36 range causing runnier melt. | Step 1: Drop nozzle temp to 262–265°C, keep front at 268–270. Step 2: Add 3–5 mm suck-back after recovery, slow suck-back to 15–20 mm/s (fast suck-back pulls air into barrel, causes next-shot splay). Step 3: If lot MVR is confirmed at 35+, consider 2°C cooler rear/middle profile. Step 4: For very long idle periods, use nozzle tip shutoff valve if available. |

Матрица выбора марки — семейство Juhai PA6 термостабилизированных и структурных
Before committing to PA6 ETF02, use this side-by-side comparison with the three other Juhai PA6/PA66 structural grades that most frequently appear alongside ETF02 in automotive and industrial bill-of-material options. All grades use Economy / Standard / Premium tier positioning as noted. Our technical sales engineers can also recommend a hybrid approach (e.g., ETF02 for hot lamp-housing reflector cup + ETF01 for cold snap-fit bezel) if your part geometry contains multiple thermal zones with different requirements.

Когда выбирать PA6 ETF02 по сравнению с альтернативами — сводка дерева решений
- ✅ Choose ETF02 if (a) continuous air-aging exposure 120–150°C for >1 000h is required, (b) a written 150°C × 3 000h ≥ 80% tensile-retention guarantee is demanded by OEM spec, (c) carbon-black color is acceptable or preferred, and (d) cost must stay below PA66 GF heat grades.
- 🔀 Step up to ETF01 (toughened) if the part has snap-fit features or cold impact down to -30/-40°C combined with heat-aging (e.g., automotive lamp bezel in Scandinavian or Canadian winter).
- 🔀 Save money with BFE01 (Standard) if the max continuous operating temp stays below 105°C and there is no long-term heat-aging mandate — BFE01 has the same 30% GF and premium PA6 base at roughly 18% lower per-kilo cost.
- 🔀 Move to PA66 BFE04 if the spec requires HDT above 220°C, continuous use above 160°C, or the part sits within 100 mm of a turbocharger / catalytic converter hot face.

Часто задаваемые вопросы (FAQ)
PA6 ETF02 outperforms standard PA6 BFE01 dramatically at all three temperatures. At 130°C × 1 000h: ETF02 = ≥92% tensile retention vs BFE01 = ~55%. At 150°C × 3 000h: ETF02 = ≥80% retention (elongation ≥55%) vs BFE01 = <40% retention and brittle failure. At 170°C × 500h: ETF02 still maintains ~62% tensile vs BFE01 drops below 28% and specimens crumble. The CuI/KI halide stabilizer deactivates polyamide free-radical chain sites while the aromatic amine AO scavenges peroxides — this dual mechanism gives ETF02 roughly 4–5× the long-term thermal life of unstabilized PA6 GF30 in the 120–160°C range. A full retention curve chart is included in the datasheet PDF.
No. PA6 ETF02 uses an inhibited CuI/KI package where the halide salt is chelated and uniformly dispersed, preventing free ionic copper migration. The material passes IEC 60426 contact-corrosion testing against bare copper, brass, tinned copper and aluminum busbars at 120°C × 1 000h with less than 0.3 mg/cm² weight loss on the metal coupon — equivalent to non-copper-stabilized electrical-grade PA6. No green-oxide copper staining has been observed in over three years of field use on motor end brackets and lamp reflector housings. For sensitive bare-copper PCB applications, we recommend sealing the part surface with a standard polyamide-compatible primer or requesting our CTI-600V non-copper heat-stabilized option (PA6 ETF03).
The long-term continuous-use rating for PA6 ETF02 in dry air aging without mechanical overload is 150°C for 3 000 hours, after which tensile strength retention remains above 80% and elongation at break retention above 55% — meaning the part still absorbs impact without brittle cracking. For static-load structural components operating below 120°C, expected service life exceeds 20 000 hours. Short peak excursions up to 175°C are acceptable if cumulative exposure stays below 100 hours and the part is not under mechanical stress during the peak. Parts under high flexural load at temperature should be derated: consult our engineering team with your load spectrum and duty cycle and we will provide a finite-life prediction.
Carbon-black (standard black color) was selected as the default for PA6 ETF02 because it acts as a synergist with the CuI/KI + aromatic amine heat-stabilizer package: CB absorbs UV radiation, quenches surface free radicals, and modestly extends heat-retention life by ~5–7% at 150°C. Natural (unpigmented) PA6 ETF02 and custom RAL/Pantone colors are available at MOQ 5 000 кг. However, the non-black formulation does not include the CB synergist, so the published 150°C × 3 000h heat-retention guarantee is reduced from ≥80% to ≥70% tensile, and UV resistance is no longer rated. For outdoor lamp-housing programs that require a non-black aesthetic, we recommend over-molding with a thin ASA cap layer instead of pigmenting ETF02 directly.
