DER K11™ PEKK
Features
- Low Crystallization Rate
- Excellent Interlayer Bonding & Z-Axis Strength
- High Mechanical Strength & Durability
- Excellent Heat Resistance
- Broad Chemical Resistance
- Inherent Flame Resistance
- Transparent Amorphous Properties
Das K11™ PEKK ist ein Hochleistungs-PEKK-Material mit einer geringen Kristallisationsrate. Diese einzigartige Eigenschaft führt zu transparenten, amorphen gedruckten Teilen. Seine inhärente Flammbeständigkeit, hohe Temperaturbeständigkeit und außergewöhnliche Festigkeit tragen zur Herstellung von Teilen mit überragender Zwischenschichthaftung bei, insbesondere in Z-Achsen-Richtung. Dies macht PEKK zu einer idealen Wahl für Anwendungen, die hohe Festigkeit und Haltbarkeit erfordern.

Description
Low Crystallization Rate: Suppresses rapid crystallization during cooling, drastically reducing internal thermal stress and preventing warp in complex builds.
Excellent Interlayer Bonding & Z-Axis Strength: Slow crystallization allows thorough chain diffusion across print layers, resulting in superior isotropic strength.
High Mechanical Strength & Durability: Outstanding structural performance with excellent fatigue and wear resistance for heavy-duty applications.
Excellent Heat Resistance: Maintains high mechanical strength and dimensional stability at elevated continuous service temperatures.
Broad Chemical Resistance: Excellent resistance to a wide range of industrial chemicals, automotive fluids, fuels, and cleaning solvents.
Inherent Flame Resistance: Naturally flame-retardant properties with low smoke and toxicity generation, suitable for strict safety standards.
Transparent Amorphous Properties: Amorphous molecular structure provides potential optical transparency/translucency and lower volumetric shrinkage during printing.
