Description
A high-temperature, thermoplastic polymer. Introduced in 1982, polyether-imide (PEI) is transparent, tough and retains its properties to about 170C. It has good resistance to UV and gamma radiation. PEI is used as a reinforcing fiber and as a fire-resistant component in electrical boards, jet engines, and automobiles.
Synonyms and Related Terms
polyetherimide (AAT); PEI; Ultem [General Electric Co.]
Other Properties
Resistant to aliphatic hydrocarbons, alcohols, and dilute bases.
Resistant to high temperatures and to burning.
