Westlake’s Radel stock shapes are made exclusively from Solvay’s Radel Polyphenylsulfone (PPSU). This transparent straw colored amorphous thermoplastic material is known for its toughness, strength, and stiffness over a broad range of end-use temperatures from -40°C to 204°C (-40°F to 400°F). Radel also exhibits resistance to a wide range of chemicals and offers good hydrolytic stability making it an ideal material choice for applications that will see long term exposure to hot water or require repeated steam sterilization (autoclaving). Radel can be shaped by all common melt processing and thermoforming methods and is easy to machine. Radel is offered in a variety of colors.
