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. PPSU has excellent thermal and chemical resistance, making it well
suited for demanding applications in automotive, aerospace, electronics,
defense, industrial, medical, semi-con applications. Previously only
available to Stratasys customers €“ now you can print with this ultra
performance polymer.
Benefits of ThermaX PPSU
