Title:
CONDUCTIVE PLASTIC MATERIAL
Document Type and Number:
Japanese Patent JP2007009090
Kind Code:
A
Abstract:

To provide a conductive plastic material having uniform conductivity and free from scattering of electromagnetic shield effect.

The conductive plastic material is obtained by uniformly dispersing preferably 10-80 mass% metallic fiber made of stainless steel having 1-50 μm diameter and 50-500 μm length and exhibiting vortical state and optionally further ≤20 mass% metallic fiber made of stainless steel having 5-30 μm diameter and 1-15 mm length and exhibiting linear state into a thermoplastic resin. Dispersion of the metallic fiber is made uniform even if stratified flow of a resin occurs when inserting into a mold and entanglement of metallic fibers is kept favorable and conductivity and shield effect are made uniform by kneading the resin with the metallic fiber exhibiting vortical state as the metallic fiber.
