PA12 UBE 3014U
PA12 UBE 3014U Resin
Material Introduction: PA12 UBE 3014U is a flame‑retardant reinforced polyamide‑12 resin specially developed for ultra‑thin‑wall electronic components. It features ultra‑high flowability, halogen‑free eco‑friendly system, and achieves UL94 V‑0 rating at 0.25 mm thin‑wall thickness.
Main Applications
Micro‑electronic connectors (core application): USB4 Type‑C housing, 5G millimeter‑wave antenna radome (0.25 mm V‑0 & 10 Gbps signal integrity requirement).
New‑energy‑vehicle high‑voltage components: BMS insulation separators, on‑board charger sockets (CTI 600 V, arc‑resistance＞120 s).
Smart‑wear structural parts: TWS ear‑bud charging‑case hinges, smart‑watch heart‑rate‑sensor supports (0.3 mm wall thickness, 5000‑cycle opening‑closing lifetime).
Industrial‑automation precision parts: Servo‑motor encoder housings, robot PCB fixing brackets (lubricant‑resistant & anti‑EMI).
Medical‑electronic housings: Portable ultrasound‑probe shells, insulin‑pump circuit compartments (ISO 10993‑5 biocompatibility passed).

Processing Parameters
| Processing Step | Parameter Range | Key Control Points |
|---|---|---|
| Drying | 85 ℃ × 4 h vacuum drying | Moisture content ≤0.015%. Sensitive to flame‑retardant hydrolysis. |
| Barrel Temperature | Rear zone：190‑200 ℃ | ＞220 ℃ triggers flame‑retardant decomposition & HBr release. |
| Middle zone：205‑215 ℃ | ‑ | |
| Front zone / Nozzle：215‑225 ℃ | Actual melt temperature ≤230 ℃. | |
| Mold Temperature | 90‑110 ℃ | Mold temperature＜80 ℃ causes flame‑retardant migration and surface chalking. |
| Injection Speed | Ultra‑high speed (≥95% of maximum rate) | Low‑speed flow leads to uneven flame‑retardant distribution. |
| Holding Pressure | 30‑50% of injection pressure | High pressure induces internal‑stress cracking especially at sharp corners. |
| Screw Design | Dual‑alloy barrier‑type | Compression ratio 2.0‑2.2, L/D ≥22. |
| Hot‑runner System | Valve‑gate type is mandatory | Avoid flame‑retardant thermal residence; residence time＜90 s. |
