PA66 BASF A3Z Resin
PA66 BASF A3Z Resin
Material Introduction: PA66 BASF A3Z (Germany BASF) is a high‑flow, unreinforced, impact‑modified PA66 resin. Its core advantages include outstanding low‑temperature toughness, excellent processing flowability, favorable mechanical strength and electrical insulation, together with oil resistance and HB‑grade flame retardancy. It performs well in parts requiring high impact resistance and complex molding. Its inherent water‑absorption property will affect dimensional stability and partial performances; strict drying is mandatory before processing.
Main Applications
Automotive industry: Wheel covers, intake manifolds, cooling fans, door handles, fuel‑cap parts, bumpers, rear‑view‑mirror housings, under‑hood components and other parts.
Electronic‑electrical industry: Connectors, coil bobbins, timers, circuit‑breaker covers, switch housings, sockets, joints, electrical‑appliance enclosures and other parts.
Industrial parts / Consumer goods: Sports‑equipment articles (ski‑binding components, ice‑skate bases), toys, home‑appliance components, mechanical housings, gears, bearings, power‑tool housings and other products.

Injection Molding Parameters
| Processing Item | Recommended Range / Condition | Notes & Explanations |
|---|---|---|
| Drying Treatment | Hot‑air drying at 80 ℃ for 4 h; extend drying time or adopt high‑temperature vacuum drying under high‑humidity environment. | Critical operation. Control moisture content below 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 | 280‑300 ℃; alternative setting: rear/middle/front/nozzle all set to 290 ℃. | Fine‑tune according to equipment and part geometry. Avoid temperature>300 ℃ or long residence‑time to prevent material degradation. |
| Mold Temperature | 60‑80 ℃; alternative range 70‑80 ℃. | Proper mold temperature guarantees good crystallinity, surface gloss and mechanical performances. |
| Injection Pressure | Adjust per product & mold design. | Despite high flowability, sufficient pressure ensures compact parts and reduces shrinkage. |
| Injection Speed | Medium‑high speed. | Leverage high flowability for smooth filling; mold shall be well‑ventilated to prevent burn marks from trapped gas. |
| Runner & Gate | Gate dimension shall not be excessively small. | Nylon solidifies rapidly; gate location and size are critical for filling. A3Z high‑flow property allows relatively smaller gate size. |
