Radel® PPSU AM Filament MS NT1

High heat, high impact performance

Radel® polyphenylsulfone (PPSU) delivers the highest performance of the 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.

Toughness and Impact Strength

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.
