eSUN PEEK-Industrial Filament

Special plastic materials with excellent mechanical and thermal properties, high strength, toughness, and impact resistance, self-lubricating and wear-resistant properties, printable mechanical gears, flame retardant, resistance to corrosion by most chemical reagents and solvents, and high-temperature resistance Performance, heat distortion temperature is as high as 205℃. It can be used for heat-resistant parts.

Features

Chemical resistance
Heat resistance
Flame retardant
High toughness

Notes:

1. It’s better to dry the ePC filament before printing(70℃/>6H). The eBOX is suggested for use when printing the ePC filament.
2. The shrinkage of ePEEK-Industrial material is high. So pls use a printer that has a chamber to print the ePEEK-Industrial filament.
3. ePEEK-Industrial is prone to warping when printing. Pls increase the chamber temperature and plate temperature; choose a bottom plate with high flatness and high-temperature resistance; Leveling is required before printing.
4. Uneven crystallization of ePEEK-Industrial material may occur during the printing process. Try to increase the chamber temperature and reduce the cooling speed of the PEEK material; if necessary, an oven is required for post-annealing. Annealing after printing can improve mechanical performance. Put it in the oven 150 ℃/1h→200℃/1h→150℃/0.5h.
