TECAPEI™ is an amorphous thermoplastic polyetherimide (PEI) made from Sabic Innovative Plastics’ Ultem® 1000 series resins. The unreinforced 1000 series materials are translucent amber in color, and combine exceptional mechanical, thermal, and electrical properties. Washers or other stamped parts made to Ultem are FDA compliant and have very good creep and stiffness at elevated temperatures as well as good UV and radiation resistance. Machinery site windows, industrial food preparation, and medical markets are just a few applications that use this material.
- 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
TECAPI™ 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.
