Overview :

PPSU (polyphenylene sulfone resin) is an amorphous polymer with superior rigidity and toughness, offering better impact resistance and chemical resistance than polyetherimide (PEI). PPSU is one kinds of amber transparent material, easy to color and processing, and its Heat Deflection Temperature can reach 196 ℃. Withstands over 1000 cycles of steam sterilization@134℃ without any significant loss of properties. Polyphenylsulfone (PPSU) has no melting point, reflecting its amorphous nature, and offers tensile strength up to 70 MPa (10152 psi).

According to the different application environment, the molding method can be injection, extrusion and blowing. As the highest performance material of sulfone polymers, PPSU has been approved by IS010993, NSF, ACS, WARS, UL94, Reach and RoSH. So PPSU has been widely used in medical sterilization boxes, handles of dental instruments, aircraft interiors and food trays, PEX water pipe joints, ventilator humidification tanks, baby bottles and other fields.

Note: As can be seen from the data sheet above, Polyphenylsulfone (PPSU) is an amorphous, heat-resistant and transparent high-performance thermoplastic. The polymer is known for its high toughness, high flexural and tensile strength, excellent hydrolytic stability and good resistance to chemicals and heat. Compared to PSU and PES, it delivers the highest performance of our sulfone polymers, offering superior mechanical properties and chemical resistance.

Typical Application

PPSU is often an excellent choice for components that are exposed to high temperatures and corrosive media due to its exceptional chemical resistance. PPSU is widely used for aircraft interior parts, instrument handles, medical instrument components and so on.

Dental and Surgical Instruments: PPSU is a good substitute for metal in the applications of medical devices and accessories, because it is light and strong.

Food Service: PPSU is biologically inert and BPA-free, which can withstand prolonged and repeated exposure to hot water, steam, oil or grease, making it to be an excellent candidate for food service applications.

Aircraft Interiors: PPSU series products are used in aircraft cabin interiors, which requiring low heat release, low smoke generation and low toxic gas emissions. They offer exceptional toughness and impact strength, superior resistance to cleaning agents and chemical disinfectants, and molded-in color to eliminate painting.
