Abstract
According to the invention, a resin composition having an electromagnetic wave shielding effect is provided. The resin composition comprises 35 to 90 wt % of an ABS resin or a mixture of the ABS resin and an AS resin, 1 to 25 wt % of a plasticizer and 5 to 40 wt % of carbon fibers. The carbon fibers are uniformly dispersed in the resin ingredient without being broken or cut at the step of mixing and dispersing the resin components, thus exhibiting improved electromagnetic wave shielding effect.
