Chemical Resistance of Antero 840CN03 3D Printing Material

Antero™ 840CN03, a Stratasys proprietary Polyetherketoneketone (PEKK) based material filled with carbon nanotubes, is a semicrystalline high-performance thermoplastic resin known for its strength, high temperature tolerance, and excellent chemical resistance properties.

This study was conducted to characterize the chemical resistance properties of the Antero 840CN03 material formulation when exposed to representative chemicals commonly found in the aviation industry.

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. Based on previous chemical resistance literature provided by PEKK manufacturers and the prevalence of certain chemicals in the aerospace industry, a characteristic group of chemicals that would exhibit the most deleterious effects toward Antero 840CN03 was chosen. 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
  • 30% Nitric Acid (HNO3)
  • 30% Sulfuric Acid (H2SO4)
  • 60% Sodium Hydroxide (NaOH)
  • Concentrated Ammonia (NH3)

The results indicated low chemical resistance to dichloromethane, and some plasticizing effects from sulfuric and nitric acids. However, Antero 840CN03 exhibited good to excellent chemical resistance for the remaining chemicals. By demonstrating the material’s exemplary chemically resistive performance, the material has shown a competitive advantage in the aerospace industry.
