Radel® – PPSU

New Technology Plastics distributes Radel® in sheet and rod forms. Radel® PPSU material (chemically known as Polyphenylsulfone) is manufactured in standard stock shapes for machining and is most often extruded in sheet and rod using Radel® PPSU polymer.

PPSU plastic is an amorphous material, which has a high glass transition temperature and low moisture absorption. Furthermore, PPSU material has better impact strength and chemical resistance than PSU and PES from the Polysulfone group. Apart from these characteristics, PPSU polymer can withstand sterilization with superheated steam better than other members of this group of polymers and is resistant to detergents and disinfectants.

PPSU Material Properties And Specifications

PPSU Characteristics

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