PA66 BASF A3W Resin
PA66 BASF A3W Resin
Material Introduction: PA66 BASF A3W (Germany BASF) is a high‑flow, unreinforced general‑purpose injection‑molding PA66 resin. Its core advantages are excellent processing flowability, good mechanical strength, heat‑aging resistance, oil resistance and electrical insulation, with UL94 V‑2 flame‑retardant rating. Its inherent water‑absorption property will affect dimensional stability and partial performances; strict drying is mandatory before processing.
Main Applications
Automotive industry: Wheels, gears, bearings and bearing housings.
Electronic‑electrical industry: Connectors, coil bobbins, cable connectors and electrical‑insulation components.
Industrial parts: High‑stress technical components.
Other fields: Home‑appliance components and power‑tool accessories.

Injection Molding Parameters
表格
| Processing Item | Recommended Range / Condition | Notes & Explanations |
|---|---|---|
| Drying Treatment | Hot‑air drying at 80 ℃ for 2‑4 h; extend drying time or adopt high‑temperature vacuum drying under high‑humidity environment. | Critical operation. Control moisture content below 0.2% to avoid hydrolysis‑induced bubbles, silver streaks and mechanical‑property deterioration. Use immediately after drying or seal and keep warm properly. |
| Melt Temperature | 280‑300 ℃ | Fine‑tune according to equipment and part geometry. Avoid temperature＞300 ℃ or long residence‑time to prevent material degradation. |
| Mold Temperature | 40‑80 ℃ | Proper mold temperature ensures good crystallinity and surface gloss. |
| Injection Pressure | Adjust per product & mold design | Sufficient pressure guarantees compact parts despite high flowability. |
| Injection Speed | Medium‑high speed | Beneficial for filling; mold shall be well‑ventilated. |
| Runner & Gate | Gate dimension shall not be excessively small | Nylon solidifies rapidly; gate location and size are critical for filling. A3W high‑flow property allows relatively smaller gate size. |
