Polyetherimide (PEI), also trademarked as Ultem®, is an amorphous, amber-to-transparent thermoplastic. Rated for continuous use in temperatures up to 356° F (180° C), it also features high tensile strength along with good flame and chemical resistance.
Ultem® PEI is often used instead of polysulfone and is commonly specified for aerospace, automotive, medical, and packaging applications. The unfilled grade, Ultem® 1000, offers outstanding mechanicial, thermal, and environmental properties, excelling in hot air and water environments. It’s hydrolytically stable, retaining 85% of its tensile strength after 10,000 hour boiling water immersion and 100% of tensile strength after 2,000 steam autoclave cycles at 270°F. It is also resistant to UV and gamma radiation. This material can be easily machined, and it provides cost savings over ceramics in electrical applications. It also offers cost and weight savings over stainless steel in medical applications.
