Abstract
Provided is a resin composition having excellent electromagnetic wave shielding properties. A resin composition containing: a thermoplastic resin (A); graphite (B); and two or more kinds of carbon black (C), the two or more kinds of carbon black (C) including a first carbon black (C-1) having a BET specific surface area of 600 m2/g or more and a second carbon black (C-2) having a BET specific surface area of less than 600 m2/g.
Claims20
A resin composition comprising:
- a thermoplastic resin (A);
- graphite (B);
- and
- two or more kinds of carbon black (C),
- the two or more kinds of carbon black (C) including a first carbon black (C-1) having a BET specific surface area of 600 m2/g or more and a second carbon black (C-2) having a BET specific surface area of less than 600 m2/g.

A resin composition comprising:
- a thermoplastic resin (A);
- graphite (B);
- and
- carbon black (D),
- when the resin composition in a molten state is filled in a mold from a direction orthogonal to a thickness direction of a resulting resin molded article and molded to obtain a resin molded article of 100 mm in length×100 mm in width×2 mm in thickness,
- a relaxation time of an L component being 1.3 msec or less when a free induction decay curve of spin-spin relaxation of 1H obtained by measuring the resin molded article using pulsed NMR at 125° C. by Hahn Echo method is subjected to waveform separation into three curves respectively derived from three components of an S component, an M component, and an L component in ascending order of relaxation time by a least-squares method.
