PPSU Properties

Physical, mechanical, thermal, electrical, and optical properties of PPSU

PPSU (Radel® R) is a high temperature thermoplastic with outstanding impact resistance. Radel® R is resistant to hot water and steam and can withstand repeated cycles in a steam autoclave. PPSU is used for medical instrument components, instrument handles, sterilization trays, aircraft bezels and interior parts, and more.

PPSU is available in FDA compliant grades. Please ask your Curbell Plastics representative for more specific information.
