PPSU (Polyphenylsulfone) is an amorphous thermoplastic material, with a continuous use temperature range of up to 300° F (149° C).



PPSU (Polyphenylsulfone) is an amorphous thermoplastic material, with a continuous use temperature range of up to 300° F (149° C). It is categorized as an advanced engineering material, and offers high impact and chemical resistance. It delivers superior toughness, with better impact resistance and chemical resistance than polysulfone and polyetherimide. It also offers exceptional long-term hydrolytic stability when compared to other amorphous thermoplastics. It can withstand virtually unlimited steam sterilization and continuous exposure to moisture and high temperatures and still absorb tremendous impact without cracking or breaking. PPSU is inherently flame retardant, and is transparent and colorable.
