Foster Corporation, a leader in performance polymer solutions for healthcare markets, has been appointed as a North American distributor of Solvay’s Udel polysulfone (PSU) and Radel polyphenylsulfone (PPSU) resins for healthcare markets. This will include unmodified polymers and standard color formulations currently offered by Solvay. Foster also offers custom compounding of polysulfone formulations, including custom colors, for specific application requirements.
Solvay’s medical-grade Udel PSU is a rigid, high-strength, transparent polymer that offers higher heat resistance and better hydrolytic stability than polycarbonate. It retains its mechanical properties when exposed to steam and other sterilization techniques. Radel PPSU is an extremely tough, transparent polymer that can withstand more than 1,000 cycles of steam sterilization without significant loss of properties. These polysulfone polymers are frequently used for medical applications that require resistance to repeated sterilization, such as instrument trays and surgical handles.
Foster’s new role as the distributor of Udel PSU and Radel PPSU resins, including standard color formulations, will not affect Solvay’s current order fulfillment policies or its existing relationship with other distributors. Solvay Specialty Polymers will continue to accept and fill orders that are 1,000 kg (2,200 lb) or greater. Foster will fulfill orders and provide technical support to healthcare customers who require smaller quantities of standard Solvay grades.
“Solvay’s standard grades of polysulfones are in high demand for reusable medical devices. Additionally, device companies are increasingly evaluating material formulations that provide differentiated colors and performance characteristics,” said Larry Johnson, Executive Vice President at Foster Corporation. “Our expertise in polymer distribution of standard grades and custom compounding specialty formulations is unique and provides the most comprehensive polysulfone polymer solutions in the industry.”
