Radel® R (PPSU) Polyphenylsulfone

BEST IMPACT & STEAM RESISTANCE TO 400°F (205°C)

- Impact resistant - High modulus of elasticity and heat resistance
- Highly resistant to steam autoclaving - FDA Compliant

Radel® R polyphenylsulfone (PPSU) is an amorphous high performance thermoplastic offering better impact resistance and chemical resistance than polysulfone and polyetherimide (Ultem® PEI).

Radel® offers superior hydrolysis resistance when compared to other amorphous thermoplastics as measured by steam autoclaving cycles to failure. In fact, Radel®R has virtually unlimited steam sterilizability. This factor makes it an excellent choice for medical devices as steam autoclaves are widely used to sterilize medical devices. It also resists common acids and bases-including commercial washing solutions- over a broad temperature range.

Radel®R is stocked in natural (bone white) and available in transparent and custom colors. It is commonly used in sterilization trays, dental and surgical instrument handles, and in fluid handling coupling and fitting applications. Radel®R is USP Class VI compliant.

It is suitable for use in electronic assembly equipment and devices that must withstand solder temperatures. Radel® has a heat deflection temperature of 405°F (207°C).

Proven applications include:

  • Medical wands
  • Endoscopic probe positioning ferrule

ENGINEERING NOTES

Radel®R has been approved for use in a variety of medical devices, it is FDA compliant and so it is appropriate for food contact applications. Radel® is not a wear material, and its properties degrade when exposed to sunlight.
