PEKK-C | Excellent FDM printed Neat Filament

PEKK-C
PEKK-C (PolyEtherKetoneKetone) is made using Arkema Kepstan® PEKK [ 70/30 copolymer] and is one of the highest-performance materials in the world while also being one of the easiest to print ultra-polymers.

Benefits of PEKK-C Include:

• High thermal properties with a CUT of 260°C (POSSIBLE ONLY POST ANNEALING), Tg of 162°C, and a Tm of 335°C
• Substantially easier to 3D print than PEEK
• Wide processing window from 345-375°C
• Inherently flame resistant (UL94 V-0)
• Low smoke generation
• Outstanding mechanical, thermal, and chemical resistance

Filament Specifications:
• 1.75mm +/- 0.05mm in diameter

 

Recommended Print Settings:

• Extruder Temps:  345 – 375°C
• Bed Temps:  125 – 140°C
• Bed Prep:  Rough Borosilicate Glass with PVP gluestick, or High temp carbon fiber sheet plus PVP glue stick, we also recommend the Vision Miner Nano Polymer
• Nozzle: We strongly recommend a 0.4mm orifice or larger using one of our Carbide nozzles
• Drying Instructions:   Please dry @110-120°C for 12-24 hours, for the first dry its recommended to dry for at least 24 hours before using, the drying time can be lowered using a vacuum oven and also storing the filament in a degassing chamber when not in use.
• Enclosure temp (if your printer is equipped):  70 – 140°C [hotter is better, up to 140°C] See More

Importance of PEKK-C in Industries

PEKK-C (Crystalline Poly Ether Ketone Ketone) is a game-changing material in industrial applications, thanks to its exceptional thermal, mechanical, and chemical properties. It is part of the PAEK family and is particularly valued for its strength, durability, and ease of use in 3D printing. Here’s why PEKK-C is critical for various industries:

1. Aerospace Industry:

1. High Thermal Resistance:With a service temperature of ~265°C (annealed), PEKK-C can withstand extreme heat, making it ideal for aerospace components.
2. Lightweight Strength:Offers the necessary strength-to-weight ratio for aircraft parts, reducing overall weight without compromising durability.
3. Flame Retardancy:Its UL94 V-0 rating and low smoke generation make it perfect for high-safety standards in aviation.

2. Automotive Industry:

1. Chemical Resistance:PEKK-C is resistant to oils, fuels, and greases, making it suitable for engine parts, housings, and fuel systems.
2. Dimensional Stability:Ensures precision and stability in 3D-printed parts for vehicle interiors and functional components.
3. Heat Deflection Temperature:With a Tm of ~335°C, PEKK-C performs well in high-heat environments like under-the-hood applications.

3. Manufacturing and Engineering:

1. Durability: Its excellent wear and abrasion resistance make it ideal for gears, bearings, and industrial machinery parts.
2. Ease of Printing: A wide processing window (350–380°C) and better printability compared to PEEK make it practical for rapid prototyping and production.
3. Mechanical Strength: With a modulus of up to 3 GPa, PEKK-C delivers unmatched toughness for high-stress applications.

4. Medical Industry:

Biocompatibility Potential: Though specific grades are required, PEKK-C shows promise in medical devices and implants due to its chemical inertness and strength
