Polyether imide (PEI) is a transparent thermoplastic material, which is a resin resistant to heat, impact and creep and has high hardness. Polyether imide is comparable to materials such as polysulfone, polyphenylene sulfide and polyketone in terms of thermal resistance. Among the other properties of this polymer, the following can be mentioned.

• High strength-to-weight ratio
• Thermo-oxidative stability
• Excellent mechanical properties
• High temperatures resistance and more…

In addition to the basic and key characteristics of the PEI polymer that was mentioned earlier, the PEI polymer also has a series of other characteristics that must be considered before choosing a specific thermoplastic.

• high deflection temperature
• retention of mechanical properties
• good electrical properties
• flame resistance
• good hydrolytic stability
