Syensqo has introduced White Radel, the latest addition to its portfolio of Radel polyphenylsulfone (PPSU) solutions for biopharma applications, surgical instruments and medical devices. According to the company, the new product is considerably whiter than previous medical-grade Radel PPSU compounds.

Radel provides an alternative to traditional materials like metals, enhancing ergonomics. Medical and pharmaceutical Radel PPSU compounds meet the strictest industry guidelines and standards, including ISO 10993 biocompatibility and USP Class VI approval.

The White Radel product combines the PPSU resin’s mechanical properties — including impact strength in compliance with ASTM D6394-21a — with the bright white aesthetic color often preferred for medical devices. It shows stability in sterilization processes such as gamma irradiation and autoclaving, as well as chemical resistance against harsh disinfectants. Its lack of Bisphenol-A (BPA) makes it a safe and compliant alternative to other white medical polymers.

In addition, the proven design freedom and processing versatility of Radel have opened attractive opportunities for complex geometries, part integration and reduced manufacturing costs. White Radel is a high-flow material appropriate for precise and efficient injection molding of medical devices. Other grades offer exceptional melt strength and adaptability in extrusion processes. Radel filaments have successfully expanded the application potential to 3D printing for rapid prototyping and small-scale production volumes.
