PEI (polyetherimide)

PEI is an amorphous thermoplastic with high mechanical strength and stiffness.

Due to its properties, PEI is very close to polyarylsulfones. The material exhibits remarkably high creep resistance over a wide temperature range. In addition, PEI exhibits a high continuous service temperature, very good hydrolysis resistance and high dimensional stability. Due to its amorphous molecular structure, PEI is transparent and has a golden yellow hue.

Properties

The properties of PEI are:

high continuous operating temperature (170°C)
high mechanical strength
high stiffness
high creep resistance over a wide temperature range
high dimensional stability
very good hydrolysis resistance (suitable for repeated steam sterilization)
good electrical insulator
good radiation resistance

Applications

PEI can be used in the following areas:

Clamps
Distributor
Surgical probes
Insulators
Components in X-ray equipment
