When it comes to high-performance plastics, Radel® (Polyphenylsulfone, PPSU) is one of the most reliable materials available for demanding applications. With its unique combination of toughness, sterilization durability, and chemical resistance, Radel is trusted across industries where failure simply isn’t an option.
At Action Plastic Injection Molding, we’ve spent decades working with ultra high-performance resins like Radel. Our team has molded millions of parts for industries that require not only precision—but also long-term durability under extreme conditions.
Key Benefits of Radel
- Superior Sterilization Resistance – Radel can endure over 1,000 autoclave cycles without cracking, discoloring, or degrading. This makes it an ideal material for reusable medical devices.
- Impact Strength – PPSU is significantly tougher than PSU or PEI, giving it an edge in applications where durability is critical.
- Chemical Resistance – With the ability to withstand aggressive cleaning agents, disinfectants, and industrial solvents, Radel performs reliably in harsh environments.
- Heat & Flame Resistance – Radel maintains its properties at continuous-use temperatures up to 400°F (204°C) and is rated UL 94 V-0 for flame resistance.
- Biocompatibility – Radel is FDA-compliant and USP Class VI certified, making it safe for use in medical and food-related applications.
Applications Across Industries
Thanks to these advantages, Radel is widely used in:
- Medical Devices – Surgical trays, housings, handles, and dental instruments.
- Aerospace – Cabin interiors, ducting, and components meeting flame, smoke, and toxicity standards.
- Semiconductors – Fluid handling and chemical-resistant parts.
- Food & Beverage Equipment – Components requiring repeated cleaning and heat exposure.
Processing Radel with Precision
While Radel offers incredible performance, it also requires specialized molding expertise. At Action Plastic Injection Molding, our team understands the high temperatures, cycle times, and tooling requirements needed to ensure every PPSU part meets exact tolerances.
We’ve invested in:
- All-electric injection presses (22–250 tons) capable of high-temperature processing.
- In-house mold maintenance for maximum tooling life.
- Advanced quality systems and inspection technology to guarantee part consistency.
