PA6 LANXESS BKV30H2.0 Resin
PA6 LANXESS BKV30H2.0 Resin
Material Introduction: PA6 LANXESS BKV30H2.0 (Germany Lanxess) is a 30% glass‑fiber‑reinforced heat‑stabilized PA6 engineering plastic. It delivers high strength, high rigidity, good heat resistance and excellent dimensional stability, showing outstanding mechanical performance for demanding engineering applications. It is hygroscopic, so strict drying is required prior to processing.
Main Applications
Automotive industry: Engine peripheral components such as covers, intake manifolds, heat‑resistant structural parts, bearings, gears, pulleys.
Electronic & electrical: Electrical insulating parts, connectors, coil bobbins, circuit‑breaker housings and other components requiring high strength and heat resistance.
Industrial parts: Bearing cages, transmission components, wear‑resistant bushings, mechanical housings, various rollers, pulleys, pump impellers, fan blades, high‑pressure sealing rings, oil‑resistant gaskets, oil‑resistant containers.

Injection Molding Parameters
| Processing Item | Recommended Range / Condition | Notes & Explanations |
|---|---|---|
| Drying Treatment | Dry in hot air above 80℃ for 16 h; if exposed to air＞8 h, vacuum‑dry at 105℃ for ≥8 h. | Critical operation. Keep moisture ≤0.2% to avoid hydrolysis, bubbles, silver streaks and mechanical‑property loss. Use immediately after drying or seal properly for heat preservation. |
| Melt Temperature | 250‑290 ℃ (recommended for glass‑fiber reinforced grades). | Avoid temperature＞300 ℃ and long‑time residence to prevent material degradation. |
| Mold Temperature | 80‑120 ℃. For structural and glass‑fiber‑reinforced parts, mold temperature＞80℃ is required; high mold temperature is also recommended for thin‑wall / long‑flow‑path parts. | Mold temperature greatly affects crystallinity and mechanical performance. Higher mold temperature improves crystallinity, stiffness and strength yet may reduce toughness. |
| Injection Pressure | Adjust according to product and mold design. | Glass‑fiber‑reinforced material has poorer flowability than unreinforced PA6; appropriately higher injection pressure may be required. |
| Injection Speed | Up to 200 mm/s. | Fast speed benefits filling; excessive speed may cause uneven glass‑fiber orientation and poor venting. |
| Runner & Gate | Gate bore ≥0.5*t (t = wall thickness of molded part). For hot‑runner system, gate size shall be smaller than conventional runner. Minimum diameter for submarine gate ≥0.75 mm. | PA6 solidifies fast; gate location and dimension are critical. |
| Screw Speed | ‑ | Excessive shear force shall be avoided to prevent glass‑fiber damage and material overheating. |
| Back Pressure | ‑ | Proper back‑pressure helps melt homogenization and venting. |
| Molding Shrinkage | Flow direction: ~0.3%; Cross direction: ~0.7%. | Obvious anisotropy; special attention required during mold design. |
| Shutdown Notice | Purge barrel with PE / PP with good thermal stability after production or at shutdown to prevent carbonized PA6 residue. Turn off heating system for long‑term shutdown. | ‑ |
