Radel® Characteristics

Radel® – a high-performance, lightweight polyphenylsulfone thermoplastic, withstands soldering temperatures and offers the highest impact and steam resistance of any thermoplastic. Those properties make it a superior choice for parts for medical devices.

Radel® can withstand repeated steam autoclaving with no loss of dimensional stability. It is an ideal material for all types of medical instrumentation. With high dielectric strength and stability, it is also an excellent choice for electronic assembly equipment and devices.

Radel® is available in clear and custom colors. It is not appropriate for food-contact applications, and its properties will degrade when exposed to sunlight. Characteristics include:

  • High tensile strength
  • here to help 200Excellent heat resistance
  • Steam resistant to 400° F
  • Very high resistance to environmental stress
  • High dielectric strength and stability
  • Very good machining and finishing

Applications for Polyphenylsulfone

  • Dental and surgical tools and instruments
  • Insulin pens, blood glucometers, tubing, sterilization trays and cauterization devices
  • End caps and other small components for pharmaceutical and electronics equipment
  • Electronic assembly equipment
  • Fluid handling couplings and fittings
