Radel® polyphenylsulfone (PPSU) delivers the highest performance of our 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 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.
Acudel® modified PPSU offers cost advantages for applications with less demanding requirements.

Radel® polyphenylsulfone (PPSU) can withstand continuous exposure to moisture and high temperatures and still absorb tremendous impact without cracking or breaking.
The impact strength of test plaques heat aged at 190°C (375°F) for 170 hours was evaluated using a Gardner falling dart impact tester. Radel® PPSU absorbs significantly higher impact force than polyetherimide (PEI) without cracking or breaking.
Now you can get the look you want and the performance you need for medical and dental cases, trays, lids, instruments and devices. Radel polyphenylsulfone (PPSU) is available in a variety of opaque and transparent colors with reduced lead times.
