The Ultem sheet is a thermoplastic product that many manufacturers and companies find to be a highly beneficial material that is improving their businesses. This is because it saves them money due to the fact that it has high wear resistance, making it longer lasting so replacement parts and equipment maintenance is not needed as frequently. Hence, this is a type of polymer that outperforms and outlasts many other thermoplastics.
Ultem PEI (Polyether imide) has a variety of key features that make it one of the top high temperature plastics, such as:
- Incredibly good resistance to hydrolysis (acceptable for continuous steam sterilization)
- In the event of combustion it has inherent low flammability and minimal levels of smoke evolution
- Ideal dimensional stability
- High maximum allowable service temperature in air (338° F continuously)
- Incredible stiffness and strength across a broad range of temperatures
- Physiologically inert (appropriate for contact with food)
- Impressive electrical insulation and dielectric properties
- Very good high energy radiation resistance (i.e. x-rays and gamma rays)
Ultem sheet is suitable for a number of applications and is ideal for electronic and/or electrical insulators, which includes a variety of semiconductor process components, as well as various structural components that depend on rigidity and high strength at high temperatures. Furthermore, due to its incredible resistance to hydrolysis, it has the ability to hold up against repeated autoclaving cycles.
