Bookmark or Share- Ultem, or Polyetherimide (PEI) Explained - unionfab.comULTEM, a high-performance thermoplastic known scientifically as polyetherimide (PEI), stands out for its exceptional mechanical strength, heat resistance, and chemical stability. Developed originally for demanding industrial applications, ULTEM has gained widespread use across industries.
- Polyetherimide - WikipediaPolyetherimide (PEI; branded as Ultem [1]) is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. When comparing PEI to PEEK, the former is cheaper but has lower impact strength and a tighter temperature range.
- ULTEM® (Polyetherimide) - StratasysULTEM is an amorphous thermoplastic polyetherimide (PEI) material that combines exceptional mechanical, thermal, and electrical properties. Natural ULTEM® 1000 (unreinforced) is a translucent amber material.
- Aerospace Meets Additive: Everything You Need to Know About ULTEM (PEI ...ULTEM stands out from other high-performance polymers because it is uniquely designed to remain mechanically stable under extreme conditions. It can withstand temperatures upwards of 217°C for extended periods of time and remain dimensionally stable in fluctuating temperatures.
- ULTEM™ Resin - SABICThe ULTEM™ resin family of amorphous thermoplastic polyetherimide (PEI) materials offers outstanding elevated thermal resistance, high strength and stiffness, and broad chemical resistance. ULTEM resins are available in transparent and opaque custom colors, as well as glass filled grades.
