Abstract
Thermoplastic compositions include: from about 30 wt % to about 80 wt % of a polymer base resin component; from about 3 wt % to about 20 wt % of a polycarbonate component; from about 2 wt % to about 15 wt % of an impact modifier component; from about 10 wt % to about 50 wt % of a glass fiber component; and from about 0.5 wt % to about 8 wt % of a carbon additive including carbon fiber. The compositions have a dielectric constant (Dk) of at least 5 at a frequency of from 1 GHz to 30 GHz as tested in accordance with a coaxial method.
