The name of the invention is the conductive polycarbonate-siloxane composition. The thermoplastic composition includes: (a) a thermoplastic polymer including a polycarbonate component; (b) a poly(carbonate-siloxane) copolymer; and (c) 4 wt% to 25 wt% carbon black. The total siloxane content of the composition is from 2 wt% to 14 wt%. The thermoplastic composition exhibits improved physical properties, including volume resistivity, melt viscosity, impact strength, puncture impact energy, and surface resistance, compared to compositions that do not include the poly(carbonate-siloxane) copolymer Rate. |
