PA11 Arkema BESNOP20TL
PA11 Arkema BESNOP20TL Resin
Material Introduction: PA11 Arkema BESNOP20TL is a 20% glass‑fiber‑reinforced bio‑based polyamide‑11 grade. It features high strength & high rigidity, low thermal expansion with superior dimensional stability, excellent fatigue resistance and creep‑resistance performance.
Main Applications
Automotive lightweight structural parts: Electronic accelerator pedal frames, shift‑mechanism forks, turbocharger pipe supports (130 ℃ heat‑resistance).
Aerospace functional components: UAV motor brackets, satellite antenna gears (passed MIL‑STD‑810G vibration test).
Industrial precision transmission systems: Servo‑motor housings, robot joint gears (high rigidity, wear‑resistance, low inertia).
High‑end sports equipment: Carbon‑fiber bicycle brake levers, snow‑binding bases (30 % weight reduction compared with metal).
Oil‑gas exploration pressure‑resistant parts: Downhole‑sensor housings, valve control rods (H₂S corrosion‑resistant, anti‑burst‑pressure performance).

Injection Molding Parameters
| Processing Step | Parameter Range | Key Control Points |
|---|---|---|
| Drying | 80 ℃ × 6 h or 100 ℃ × 4 h | Moisture content ＜0.05%. Glass fiber is sensitive to hydrolysis. |
| Barrel Temperature | Rear zone：200‑210 ℃ | Too‑low temperature causes poor glass‑fiber dispersion. |
| Middle zone：210‑225 ℃ | ‑ | |
| Front zone / Nozzle：220‑235 ℃ | Temperature＞240 ℃ triggers PA11 molecular degradation. | |
| Mold Temperature | 70‑90 ℃ | Mold temperature＜60 ℃ greatly reduces glass‑fiber orientation degree. |
| Injection Speed | Medium‑high speed | Low‑speed brings glass‑fiber agglomeration; excessive‑speed causes jetting. |
| Holding Pressure | 50‑70% of injection pressure | Higher holding‑pressure required for high‑GF grade to avoid sink marks. |
| Screw Design | L/D≥20, compression ratio 2.0‑2.5 | Special glass‑fiber‑reinforced screw to avoid shear overheating. |
| Hot‑runner System | Mandatory requirement | Prevent cold‑plug clogging for glass‑fiber‑filled melt. |
