A PEKK-based material
Antero™ 840CN03 is a PEKK-based FDM thermoplastic combining the excellent physical and mechanical qualities of PEKK with electrostatic dissipative (ESD) properties. The material is filled 3% by weight with carbon nanotubes.
As a high-performance polymer, Antero 840CN03 exhibits exceptional chemical and wear resistance, ultra-low outgassing properties and consistent ESD performance. ESD values range from 104 – 109 ohms per square inch. This makes the material particularly suitable for space and industrial applications where these qualities are critical.
Produce prototypes and low volume, highly customized parts with consistent ESD (Electrostatic discharge safe) performance that are strong, temperature and chemical resistant, ultra-low outgassing, and with exceptional wear properties.
