TECAPEI™ black (Sabic Ultem® 1000 series)

unfilled black pei

TECAPEI black Ultem is a polyetherimide material with high mechanical strength and rigidity, that is also known for its good electrical properties.  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.
