About Polyphenylsulfone (PPSU)

Polyphenylsulfone (PPSU) is a high-performance amorphous thermoplastic polymer known for its exceptional chemical resistance, thermal stability, and impact strength. PPSU is part of the polysulfone family and offers superior performance compared to other sulfone-based polymers like PSU (Polysulfone) and PES (Polyethersulfone). It is widely used in demanding applications where toughness, sterilizability, and durability are essential, such as medical, aerospace, and industrial sectors.
