Radel® Polyphenylsulfone
Performance Across The Board

Radel polyphenylsulfone (PPSU) delivers the highest performance of our sulfone polymers, offering better impact resistance and chemical resistance than polysulfone (PSU) and polyetherimide (PEI). Its high heat resistance and excellent hydrolytic stability make it an excellent choice for hot water fittings and medical devices requiring repeated steam sterilization.

Acudel modified PSU offers cost advantages for applications with less demanding requirements.

Radel R-7000 Series products are specially formulated for use in aircraft interiors and are in compliance with stringent FAA regulations requiring low heat release, low smoke generation and low toxic gas emissions.

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

What a Show of Strength

  Radel polyphenylsulfone (PPSU) can withstand continuous exposure to moisture and high temperatures and still absorb tremendous impact without cracking or breaking.

Heat-aged test plaques evaluated using a Gardner falling dart impact tester demonstrate the superior performance of Radel PPSU.
