PEKK

Engineering Plastics
Chemical resistantImpact resistantHeat resistantFunctional

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.

Available finishes

Each finish can be combined with the available colors at checkout.

Standard

Standard

1 color

The standard (as-printed) finish on FDM parts shows the natural texture of layer-by-layer printing. The visibility of the layer lines depends on part geometry and orientation, plus light marks where support material was removed.

Sanded

Sanded

1 color

The sanded finish on FDM parts reduces the visibility of layer lines compared to the standard finish, though some surface texture generally remains. How much smoothness is achieved can vary depending on the material.
