Chemical Resistance of Antero 800NA 3D Printing Material

Antero™ 800NA is a Stratasys-proprietary polyetherketoneketone (PEKK) material that’s part of the polyaryletherketone (PAEK) family. It’s a semi-crystalline, engineering-grade thermoplastic resin known for its strength, high temperature tolerance and excellent chemical resistance.

The objective of this white paper is to document the results of experiments to characterize Antero 800NA’s chemical-resistant properties when exposed to typical aviation industry chemicals. Specifically, the study looked at what chemicals had a detrimental effect and to what extent. A specific group of chemicals that would cause the most harmful effects were chosen. The selection was based on PAEK manufacturer literature and the prevalence of these chemicals in the aviation industry. The chemical reagents are:

  • Methyl Ethyl Ketone (Butanone) – organic solvent
  • Toluene – aromatic hydrocarbon solvent
  • Dichloromethane (DCM) – geminal organic solvent
  • Ethyl Acetate – organic solvent
  • Skydrol 500B-4 – aviation hydraulic fluid
  • Jet-A – aviation fuel

The results showed lower chemical resistance to halogenated solvents for the non-annealed material.  However, Antero 800NA exhibited good to excellent resistance for the remaining chemicals prior to annealing. Additionally, all annealed specimens exhibited excellent chemical resistance to the gamut of chemicals tested. Based on these results, Antero 800NA demonstrates a competitive advantage among aerospace materials.
