Overview
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.

Radel R® is often used instead of polysulfone or Ultem® for medical applications when superior toughness or extended service life with repeated autoclave cycles is desired.

Radel R® Standard Sizes

SHEET 24"x48" (0.25"-4.0" thick)
