ELECTROMAGNETIC WAVE SHIELDING THERMOPLASTIC RESIN COMPOSITION AND PLASTIC ARTICLE

摘要

A thermoplastic resin composition for shielding electron waves is provided to realize improved electron wave-shielding property while reducing degradation of other characteristics including mechanical strength such as impact resistance. A thermoplastic resin composition for shielding electron waves comprises: 100 parts by weight of a thermoplastic resin comprising a polycarbonate resin, polyester resin or a blend thereof; 1-30 parts by weight of stainless metal fibers; and 0.01-10 parts by weight of carbon nanotubes. The polycarbonate resin includes a polycarbonate resin having a weight average molecular weight of 15,000-50,000 g/mol. The stainless metal fibers include ferrite type metal fibers or ostenite type metal fibers.
