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.
MAIN CHARACTERISTICS
* High maximum allowable service temperatures in air (180°C, 170°C and 150°C continuously for PPSU 1000, PEI 1000 and PSU 1000 respectively)
* High mechanical strength, stiffness and creep resistance, also at elevated temperature
* Excellent hydrolysis resistance (suitable for repeated steam sterilisation)
* High toughness, even at low temperatures
* Physiologically inert (suitable for food contact)
* Very good dimensional stability
* Translucent, non-optical quality (except for PPSU 1000 which is black)
* Very good resistance against high energy radiation (gamma and X-rays)
* Good electrical insulating and dielectric properties
PEI 1000 natural (amber, translucent) [PEI]
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.
* Quadrant Engineering Plastic Products does not allow, approve or support human implantable applications utilising this material.
