| TECAPEI™ is an amorphous thermoplastic polyetherimide (PEI) made from Sabic Innovative Plastics’ Ultem® 1000 and 2000 series resins. The unreinforced 1000 series materials are translucent amber in color, and combine exceptional mechanical, thermal, and electrical properties. The addition of glass fiber reinforcement in the 2000 series, coupled with Ensinger’s proprietary extrusion techniques, provides the TECAPEI™ with both greater tensile strength and rigidity, while also improving dimensional stability. TECAPEI has many applications in medical, electronic/electrical, microwave, automotive, and aircraft industries. Excellent mechanical strength Outstanding heat resistance Exceptional resistance to environmental forces Inherent flame resistance with low smoke evolution High mechanical strength High dielectric strength Low dissipation factor over a wide range of frequencies Excellent machinability and finishing characteristics&& |
