PPSU
High temperature thermoplastic material with outstanding impact resistance that is autoclavable
PPSU (polyphenylsulfone) (Radel® R) is a high temperature thermoplastic material with outstanding impact resistance. Radel® R is resistant to hot water and steam and can withstand repeated cycles in a steam autoclave. FDA compliant grades of PPSU are available. For PPSU chemical resistance view our chart.

PPSU Properties and Material Options
Radel® R-5500– is a general purpose extrusion grade of polyphenylsulfone (PPSU) offering exceptional hydrolytic stability and better toughness than most commercially available high temperature polymers.
Tech Tip– PPSU is often used instead of polysulfone or Ultem® for medical applications when superior toughness or extended service life with repeated autoclave cycles is desired.
