Sulfone Polymer Center

Udel® Polysulfone (PSU)

 Transparent (light yellow color)
 Heat deflection temperature of 174°C (345°F)
 Oxidative stability
 Hydrolytic stability
 Good chemical resistance
 Steam sterilizable up to 100 cycles

Polysulfone is often used when performance requirements exceed the capabilities of polycarbonate. This includes higher heat resistance, improved chemical resistance and steam sterilization.

Radel® R Polyphenylsulfone (PPSU)

 Transparent (light amber color)
 Heat deflection temperature of 204°C (399°F)
 Outstanding toughness and impact strength
 Good chemical resistance
 Excellent hydrolytic stability
 Steam sterilizable over 1000 cycles

Polyphenylsulfone should be considered for more challenging applications, such as those needing even higher heat resistance, broader chemical resistance or exceptional impact strength and toughness.
