PPSU

PPSU Rods, Plates & Tubular Bars

Radel® polyphenylsulfone (PPSU) delivers the highest performance of sulfone polymers, offering better impact resistance and chemical resistance than polysulfone (PSU) and polyetherimide (PEI). The high heat resistance and excellent hydrolytic stability of Radel® PPSU make it an excellent choice for hot water fittings and medical devices requiring repeated steam sterilization. Radel® polyphenylsulfone (PPSU) can withstand continuous exposure to moisture and high temperatures and still absorb tremendous impact without cracking or breaking.

Key Features

  • High HDT of 207°C (405°F)
  • Superior toughness and impact strength
  • Exceptional long-term hydrolytic stability
  • Better chemical resistance than PSU and PEI
  • Withstands over 1,000 cycles of steam sterilization without any significant loss of properties
  • Inherently flame retardant
  • Transparent
  • Colorable

Typical Applications

  • Sterilization cases and trays
  • Dental and surgical instruments
  • Medical devices
  • Aircraft interiors
  • Airline catering trolleys
  • Hot water fittings
  • Plumbing manifolds
  • Food service trays
