Claim 0:
1. A thermoplastic compound in the form of a pellet, the thermoplastic compound comprising:
(a) thermoplastic resin; and
(b) conductive fibers enveloped by the thermoplastic resin and distributed within the pellet such that each of at least 50% of the conductive fibers is substantially surrounded by the thermoplastic resin and thereby substantially separated from physical contact with any other of the conductive fibers;
wherein the pellet has a pellet length and each of the conductive fibers has a fiber length, and wherein the fiber length of each of at least a portion of the conductive fibers is substantially equivalent to the pellet length; and
wherein the thermoplastic compound, when molded at a thickness of about 3.2 mm, has an electromagnetic shielding effectiveness across a range of frequencies from about 0.5 GHz to about 2.0 GHz of at least about 60 dB according to ASTM D4935.
