Material properties of polyetherimide (PEI)

PEI, manufactured from ULTEM® granules, has excellent thermal, mechanical and mechanical properties and electrical properties as well as excellent natural flame retardancy and a particularly low smoke development in case of fire. PEI is therefore very suitable for electrical/electronic insulators and a variety of load-bearing components, of which high strength and stiffness at higher temperatures is demanded. Thanks to the good hydrolysis resistance of polyethermide, it is obvious that medical devices and analytical instruments represent an important field of application for this material.

PEI offers high toughness even at low temperatures, very good resistance to high-energy radiation (gamma and X-rays), very high dimensional stability and is physiologically safe.
