ThermaX™ PPSF (PPSU) 3D Printing Filament

Polyphenylsulfone (PPSF or PPSU) is a high-temperature aromatic sulfone polymer.  Long considered to be one of the highest performance polymers in the plastics world.  PPSF has excellent thermal and chemical resistance, making it well suited for demanding applications in automotive, aerospace, electronics, defense, industrial, medical, semi-con applications.   

ThermaX™ is 3DXTECH's brand of high-temperature polymers designed specifically for 3D printing the highest performance parts possible.  PPSU is sold using names such as Solvay's Radel R and BASF's Ultrason P.
