PPSU materials

PPSU material - Polyphenylsulfone

PPSU plastic (chemically known as polyphenylsulphone) is an amorphous material with a high glass transition temperature and low moisture absorption. PPSU polymer belongs to the polysulphone group but offers better impact strength and chemical resistance compared to PSU and PES. In addition, PPSU can withstand sterilisation conditions with superheated steam better than other plastics in this polymer group. At the same time, the material PPSU offers resistance to cleaning agents and disinfectants.

Manufactured PPSU products and PPSU parts

Ensinger is PPSU manufacturer and supplies PPSU material as standard stock shapes, as well as in the form of PPSU filament, compounds and profiles. In addition, Ensinger offers the service of contract compounding.

Due to the PPSU material properties, the processing spectrum into finished parts is highly diverse.

Here, Ensinger can serve a broad range from prototypes from additive manufacturing, to machining and injection molded components. Ensinger is a specialist in PPSU when it comes to certified production in accordance with ISO 13485 standards in the areas of additive manufacturing and machined parts.

  • Low moisture absorption to achieve tolerances

PPSU applications

Medical: test implants/artificial joints for hip, knee, shoulder, handle of medical equipment 

Biopharma: Measuring instruments

Kneel trial implant

Knee trial implants

made of TECASON P MT

Test Implants for Knee Joint Reconstruction

Manufacturers of knee reconstruction products are now in a global market for sales and customers. Apart from the actual implant, tools and instruments are of increasing importance. These facilitate handling during the operation, enhance patient safety and may even reduce the follow-up expenses for reprocessing. These instruments include test implants, which sometimes serve to differentiate products from the competitors.
