PPSU (Polyphenylsulfone)

PPSU is a novel thermoplastic engineering plastic, referring to high-molecular-weight compounds containing sulfone groups and aromatic nuclei in the molecular main chain; it is non-crystalline. PPSU is an amorphous thermoplastic plastic, possessing high transparency and high hydrolytic stability. Products made from it can withstand repeated steam sterilization.

ESD PPSU

ESD PPSU is a static-dissipative Polyphenylsulfone offering high purity, heat resistance, and excellent sterilizability.
