PPSU 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.
Typical properties of PPSU
|Izod impact (notched)
||ft-lbs/in of notch
|Heat deflection temperature @ 264 psi
|Maximum continuous service temperature in air
|Water absorption (immersion 24 hours)
|Coefficient of linear thermal expansion
