PA66 BASF A3EG3 Resin
PA66 BASF A3EG3 Resin
Material Introduction: PA66 BASF A3EG3 (Germany BASF) is a reliable‑performance 15% glass‑fiber‑reinforced PA66 engineering plastic. It features good rigidity, dimensional stability, heat resistance, oil resistance and chemical resistance, together with excellent 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: Electrical components (electrical housings, connectors), electronic insulating parts, wires & cables and coil‑molding components.
Automotive industry: Automotive under‑hood parts, automotive electronic components and automotive anti‑collision beams.
Mechanical parts & Industrial fittings: Mechanical components, housings, shields, bearing cages, various handles and support frames.
Other fields: Equipment and mechanical components.

Injection Molding Parameters
| Processing Item | Recommended Range / Condition | Notes & Explanations |
|---|---|---|
| Drying Treatment | Hot‑air drying at 80 ℃ (176 °F) for 2‑4 h. Extend drying time or use higher‑temperature vacuum drying under high‑humidity conditions. | Critical operation. Control moisture content ≤0.15% to avoid hydrolysis‑induced bubbles, silver streaks and mechanical‑property deterioration. Use immediately after drying or seal and keep warm properly. |
| Melt Temperature | 260‑270 ℃ (500‑518 °F). | Fine‑tune according to equipment and part geometry. Avoid temperature＞300 ℃ or long residence‑time to prevent material degradation. |
| Mold Temperature | 80‑100 ℃ (176‑212 °F). | Proper mold temperature ensures good crystallinity, surface gloss and mechanical performances. |
| Injection Pressure | 750‑1250 bar (approx.508‑1810 psi). | Adjust per product & mold design. |
| Injection Speed | High‑speed injection (moderately reduce speed for reinforced grades). | Fast filling facilitates melt flow; good mold venting is required. |
| Screw Speed | 30‑60 rpm. | Avoid excessive shear heat generation. |
| Runner & Gate | Gate bore ≥0.5*t (t = part wall thickness). Gate location is critical for PA66 due to short solidification time. | ‑ |
| Cooling Time | 20‑90 s. | Depends on part wall thickness and mold temperature. |
| Injection Machine Type | Screw‑type injection molding machine. | ‑ |
