PEI 9085 3D Printing Filaments Product Description
| ✅ | High-temperature resistant |
1.Glass transition temperature: 215-217 °C 2.Heat distortion temperature: 220°C 3.Long-term using temperature: 170°C 4.Short-term using temperature: 200°C |
✅ | High printing precision |
| 9085 is an amorphous material with a relatively high glass transition temperature and softening temperature, offering better printing accuracy than PEEK material |
✅ | Easy printing |
| Boron nitride nanotubes can withstand high temperatures up to 900°C, while the nozzle temperature for printing PEI9085 is only 350-390°C. Therefore, they are less likely to clog the nozzle and are easier to print. |
✅ | Flame retardant UL-94V0 |
| Typical Applications of PEI 9085
Under-hood automotive components & sensor housings
✈️ Aerospace brackets, clips & functional prototypes
High-temperature electronic enclosures (UL 94 V‑0)
Semiconductor & SMT fixture jigs
⚙️ Replacement parts for metal/PEEK where cost matters
