PA66 BASF A3EG10 Resin
PA66 BASF A3EG10 Resin
Material Introduction: PA66 BASF A3EG10 (Germany BASF) is a high‑performance 50% glass‑fiber‑reinforced PA66 engineering plastic. It delivers ultra‑high strength, ultra‑high rigidity, excellent heat resistance and dimensional stability, together with good electrical‑insulation performance and HB‑grade flame retardancy. Its inherent water‑absorption property will affect dimensional stability and partial performances (large performance difference between dry and conditioned state); strict drying is mandatory before processing.
Main Applications
Electronic‑electrical industry: Insulation materials for electrical wires, electronic insulating parts and industrial fittings.
Automotive industry: Automotive components, various structural parts manufactured relying on high strength and heat resistance.
Mechanical parts: Engineering & industrial fittings requiring high rigidity and dimensional stability.

Injection Molding Parameters
| Processing Item | Recommended Range / Condition | Notes & Explanations |
|---|---|---|
| Drying Treatment | Hot‑air drying at 80 ℃ for at least 4 h. | Critical operation. Control moisture content ≤0.15%. Use immediately after drying or seal and keep warm properly. |
| Melt Temperature | 280‑310 ℃. | Fine‑tune according to equipment and part geometry. Avoid temperature＞310 ℃ or long residence‑time to prevent material degradation. |
| Mold Temperature | 80‑90 ℃. | Proper mold temperature ensures good crystallinity and mechanical performance. |
| Injection Pressure | Adjust per product & mold design. | Appropriately increase injection pressure for glass‑fiber reinforced grade. |
| Injection Speed | Screw speed ＜300 mm/s. | Excessive shear force shall be avoided to prevent glass‑fiber damage and material overheating. |
| Molding Shrinkage | Flow direction:0.33%; Transverse direction:0.82%. | Obvious anisotropy, special attention shall be paid during mold design. |
