Syensqo (Solvay Specialty Polymers) Acudel® 22000 Modified Polyphenylsulfone (PPSU), Unreinforced
Categories: Polymer; Thermoplastic; Polyphenylsulfone (PPSU)

Material Notes: Unreinforced, general purpose for injection molding

Acudel® 22000 is a modified polyphenylsulfone. It is a high-heat, high-performance resin formulation exhibiting very good hydrolytic stability, excellent resistance to acids and bases and good resistance to stress cracking under a broad range of chemical environments. In addition, Acudel® 22000 resin exhibits robust toughness and improved notch resistance compared to both Udel® polysulfone and Veradel® polyethersulfone, although slightly lower than that of neat Radel® polyphenylsulfone. In general, the performance profile of Acudel® 22000 resin falls between polysulfone and polyphenylsulfone.

In addition to its high mechanical and thermal performance attributes, Acudel® 22000 resin also offers very good electrical properties over a broad temperature range as well as inherent flame retardancy.
