PEI

PolyEtherImide

SCROLL

PEI is an amorphous thermoplastic with a high mechanical strength and rigidity.


Its properties make PEI very similar to polyphenylensulfone. This material demonstrates a wide range of temperatures and an impressively high creep strength. PEI also has a high continuous service temperature (170°C). Additionally, both its hydrolysis resistance and dimensional stability are very good, rounding off its properties profile. PEI’s amorphous molecule structure makes it transparent and it has a goldish-yellow colour. It is a good electrical insulator. Important: Oil-soluble coolants should not be used when machining PEI, as this can lead to cracks forming.
