INFINAM® PEEK 9359 F - New plastic filament for industrial applications in 3D printing

Our PEEK filament material is distinguished with the following properties:

  • excellent performance in heat resistance and chemical resistance,
  • good warpage resistance,
  • unique crystallization which gives significantly improved adhesion between layers in the vertical direction,
  • compared to 3D printed stainless-steel parts, it is 80% lighter in weight and 30% tougher with excellent fatigue resistance making it an ideal substitution to 3D printing metal,
  • superior wear resistance and low sliding friction which makes it suitable for producing lightweight structural parts,
  • long-term temperature resistance at 250℃ and short-term temperature resistance at or above 300℃,
  • resists most organic and inorganic chemicals and only dissolves in concentrated sulfuric acid and nitric acid,
  • Inherently flame retardant with low smoke and toxicity,
  • Resistant to gamma radiation, 250C steam and hydrolysis,
  • excellent wave transmission performance than metal does.
