This unreinforced amorphous thermoplastic material has a lot
of features in common with PPSU and PSU. All three offer a combination of excellent mechanical, thermal and electrical properties.
PEI 1000 stock shapes are produced from ULTEM® resin. This advanced polymer features a combination of outstanding thermal, mechanical and electrical properties, together with very low flammability and low levels of smoke evolution during combustion making it extremely suitable for electrical / electronic insulators and a variety of structural components requiring high strength and rigidity at elevated temperatures. Thanks to the good hydrolysis resistance of polyetherimide and because the raw material used for the production of PEI 1000 stock shapes is USP Class VI compliant, medical devices and analytical instrumentation are obviously important application fields.
Also referred to as Ultem 1000.
