PPSU Film

Formula: PPSu

Form: Foil/Film/Sheet

Material: Polyphenylsulfone (PPSU, PPSF)

Commodity: Polymers

Thickness: 5.5mm

PPSU films are made from a type of polyphenylsulfone plastic. They are available in a range of 5 sizes and thicknesses to suit different design requirements. As a high-performance thermoplastic polymer, PPSU offers excellent thermal and mechanical properties, as well as chemical and hydrolytic resistance. With their combination of strength, stiffness and dimensional stability, PPSU films have applications in aerospace, semiconductor handling and medical devices, where precision parts are needed that can withstand repeated autoclaving and chemical sterilization.
