PEKK

Material details

PEKK (Polyetherketoneketone) filament is a high-performance thermoplastic in the PAEK family, renowned for its exceptional thermal, chemical, and mechanical properties. It excels in environments demanding resistance to high temperatures, maintaining integrity and performance under extreme conditions. This makes PEKK a preferred choice in aerospace, automotive, and industrial sectors.
One key advantage of PEKK is its remarkable chemical resistance. It withstands a wide range of chemicals, including acids and solvents, making it ideal for chemical processing industries. Additionally, its high thermal stability enhances its suitability for high-temperature applications.
Mechanically, PEKK offers significant strength and rigidity, essential in high load-bearing and durability-required environments. Its low emission of smoke and toxic gases under flame conditions aligns with strict fire and safety standards in aerospace and transportation.
