New white PPSU resin enables bright medical devices with outstanding mechanical performance, chemical resistance and biocompatibility
Syensqo, a leading global provider of high-performance materials and chemical solutions, has introduced White Radel®, the latest innovation in its portfolio of Radel® polyphenyl sulfone (PPSU) solutions for durable biopharma applications, surgical instruments and medical devices. The new product is considerably whiter than traditional medical grade Radel® PPSU compounds.
We are proud to celebrate 35 years of Radel® PPSU. With its high heat and chemical resistance as well as excellent mechanical strength and repeated sterilizability, the polymer has emerged as a cornerstone in our advanced materials offering for the healthcare industry, helping our customers push the boundaries for safer, more efficient and sustainable products.
Radel® has significantly influenced the medical industry by providing an innovative alternative to traditional materials like metals. Its high strength-to-weight ratio enhances ergonomics for medical professionals, facilitating the manipulation of tools. Moreover, medical and pharmaceutical Radel® PPSU compounds meet the strictest industry guidelines and standards, including ISO 10993 biocompatibility and USP Class VI approval.
The novel White Radel® product combines the PPSU resin’s outstanding mechanical properties, including high impact strength in compliance with ASTM D6394-21a, with the bright white aesthetic color often preferred for medical devices. It shows excellent stability in sterilization processes such as gamma irradiation and autoclaving, as well as durable 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. As a high-flow material, White Radel® is an ideal choice for the precise and efficient injection molding of medical devices. Other grades offer exceptional melt strength and adaptability in extrusion processes. Moreover, semi-finished components can be machined with ease, while Radel® filaments have successfully expanded the wide application potential to 3D printing for rapid prototyping and small-scale production volumes.
Beyond the company’s diversified medical materials portfolio, Syensqo offers its customers a comprehensive training program in everything from basic polymer knowledge, design and processing to failure analysis, regulatory, safety and sustainability issues as well as market-specific considerations.
