TECAPEI unfilled Ultem
TECAPEI is a Polyetherimide based polymer, sometimes also known as PEI material, and is an amorphous thermoplastic with high mechanical strength and rigidity.
Polyetherimide or PEI polymer is extruded by Ensinger in sheet and rod shapes, using Sabic Ultem® resin. Unfilled PEI thermoplastic is translucent and amber in color, and combines exceptional mechanical, thermal and electrical properties.
Often referred to as Ultem® plastic, polyetherimides are very similar in their physical characteristics to the polyarylsulphones, while simultaneously offering significant advantages. This material has a remarkably high creep resistance over a wide range of temperatures and furthermore, polyetherimides have a high permanent operating temperature. Very good resistance to hydrolysis, along with dimensional stability rounds out the portfolio of typical polyetherimide properties.
- Excellent mechanical strength
TECAPEI™ exhibits high tensile strength at room temperature and retains a significant portion of this strength at elevated temperatures.
Glass fibers further increase high-temperature strength.
- Outstanding heat resistance
TECAPEI™ retains its physical properties at elevated temperatures.
- Exceptional resistance to environmental forces
Environmental characteristics of TECAPEI™ include it's stress resistance.
- Inherent flame resistance with low smoke evolution
Tested internally to UL 94 V-0.
- High mechanical strength
- High dielectric strength
- Low dissipation factor over a wide range of frequencies
- Excellent machinability and finishing characteristics
TECAPEI™ can be easily machined with conventional metalworking tools, painted, hot stamped, printed, or metallized.
TECAPEI has many applications in medical, electronic/electrical, microwave, automotive, and aircraft industries.
