For the most challenging applications – requiring repeated sterilization or uncompromising toughness – choose Radel R 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. It is inherently flame retardant and offers exceptional resistance to bases and other chemicals.
