Antero™ 840CN03 is a PEKK-based FDM thermoplastic with built-in electrostatic dissipative (ESD) properties, designed for high-strength, chemically resistant, and low-outgassing applications. It delivers a lightweight alternative to metal for aerospace, electronics, and advanced industrial production environments.
specified PEKK with Integrated ESD Protection
Antero™ 840CN03 is a PEKK-based FDM thermoplastic engineered for applications where electrostatic discharge control, mechanical strength, and environmental resistance are critical. It combines the inherent performance of PEKK with consistent ESD properties, enabling reliable use in sensitive electronic and aerospace systems.
Strength, Heat, and Chemical Resistance
This material offers excellent mechanical performance, toughness, and wear resistance, along with strong resistance to fuels, oils, hydraulic fluids, and industrial chemicals. Its ability to maintain performance at elevated temperatures makes it suitable for demanding production and tooling applications.
Ultra-Low Outgassing for Aerospace Applications
Antero™ 840CN03 exhibits ultra-low outgassing characteristics, supporting use in aerospace and space environments where material emissions must be tightly controlled. This makes it well suited for avionics housings, spacecraft components, and other controlled assemblies.
Additive Manufacturing Advantages
By leveraging FDM technology, Antero™ 840CN03 enables complex, lightweight geometries that are difficult or impractical to machine from bulk PEKK. Additive manufacturing reduces material waste, shortens lead times, and lowers overall production costs while maintaining consistent material performance.
