Characteristics and applications
Same good electrical and mechanical properties as Etronit IV C, but the tubes are black throughout. For constructions in which a decorative element is important.
Notes:
A) ID > 8 mm and/or OD > 10 mm
B) Wall thickness
C) 230 MPa measured at 150°C
D) Wall thickness ≥ 4,0 mm
