PEKK: The High-Performance 3D Printing Material
Polyetherketoneketone (PEKK) is a semi-crystalline thermoplastic belonging to the PAEK family, renowned for its outstanding mechanical and chemical properties. Known for its exceptional performance in extreme environments, PEKK is a superior choice for additive manufacturing, particularly in demanding industries such as aerospace, automotive, and petrochemical.
PEKK, like PEEK, offers strong mechanical and chemical resistance but is easier to print due to its lower crystallization rate and melting point. Although more expensive, PEKK is preferred in aerospace for its printability and high performance.
High Strength and Durability
PEKK exhibits remarkable mechanical strength and dimensional stability.
Ease of Printing
Compared to its counterpart PEEK, PEKK is easier to print due to its lower melting point and slower crystallization rate.
Chemical Resistance
This material can withstand a wide range of solvents, acids, and bases.
Thermal Properties
Melting points typically ranging from 340 to 360 °C.
Application Scenarios
Automotive
Its resistance to high temperatures and chemicals makes PEKK suitable for parts exposed to harsh conditions.
Oil and Gas
Its resistance to high temperatures and chemicals makes PEKK suitable for parts exposed to harsh conditions.
Aerospace
Ideal for manufacturing lightweight components, PEKK’s strength-to-weight ratio is crucial for optimizing aircraft performance.
