Description


What is PPSU?

 
PPSU is the highest performance amorphous polymer and made by the reaction of 4,4´-dichlorodiphenylsulfone (DCDPS) with bisphenol. The material is used in very demanding, high temperature applications. Heat deflection temperature is 207 °C (405 °F), it can withstand continuous exposure to heat and still absorb extremely high impact without deflecting or breaking. Its chemical resistance is higher than most other amorphous polymers.
 

Characteristics:

 
-       High operating temperature (180°C)
-       Good chemical compatibility
-       Very high impact strength
-       High dimensional stability
-       High rigidity over a wide range of temperatures
-       Excellent resistance to hydrolysis (suitable for repetitive steam sterilisation)
-       Very good resistance against high energy radiation (gamma and X-rays)
-       Good electrical insulating properties
-       Favorable dielectric characteristics

Applications:

 
PPSU is most widely used in the medical market. Medical devices require high strength materials to sustain repeated sterilization, while maintaining their performance. PPSU resin offers extremely high impact strength plus excellent chemical resistance, which allows it to successfully withstand repeated steam sterilization and harsh boiler additives. PPSU is also extremely resistant to stains caused by disinfecting solutions. Medical applications for PPSU include medical trays and containers, surgical instruments, a binocular ophthalmoscope and a bellow housing for anaesthetics. Other applications for PPSU are institutional food service trays and aircraft interiors.
