Sterilizable Dental Instruments

A Superior Lightweight alternative to Metal

Radel® PPSU Can Withstand Over 1,000 Autoclave Cycles


Lightweight polymers are often preferred over metal to reduce the hand-fatigue users commonly experience with heavier, less ergonomic designs. These medical-grade polymers must withstand the rigors of steam sterilization. For over 30 years, Radel® PPSU has provided a strong, lightweight option for surgical and dental instruments that can be steam sterilized over 1,000 times without significant loss of properties or appearance.


Superior Lightweight Strength

This remarkably strong polymer has successfully replaced metals, like stainless steel and aluminum, in a wide variety of reusable instruments:



Instruments made from Radel® PPSU can be injection molded into more ergonomic designs that are too expensive to achieve by machining metal. Plus, they can be overmolded with silicone to improve grip and reduce practitioner fatigue.


The success of Radel® PPSU can be attributed to several key performance attributes that are inherent to the polymer.

It offers excellent impact strength and better chemical resistance than either polysulfone (PSU) or polyetherimide (PEI).

Additionally, the material is certified to ISO 10993 standards for biocompatibility.
