More Performance Across the Board
Radel® polyphenylsulfone
 For the most challenging applications – requiring repeated sterilization or uncompromising toughness – choose Radel polyphenylsulfone (PPSU). With a high heat deflection temperature of 405°F (207°C), it can withstand continuous exposure to heat and still absorb tremendous impact without cracking or breaking (Click here for video). It is inherently flame retardant and offers exceptional resistance to bases and other chemicals.
Key Features
- 207°C HDT
- Superior toughness
- Exceptional hydrolytic stability
- Good chemical resistance
- Transparent
- Colorable
- Steam sterilizable with better retention of impact properties (more..)
