A PEKK-based material
ESD PEKK (electrostatic dissipative polyetherketoneketone) is a thermoplastic with static dissipative properties for applications where a static charge can damage products or impair performance.
It has excellent chemical resistance and favorable mechanical and thermal properties, making it appropriate for demanding applications that require resistance to electrostatic discharge.
