Abstract
A polyolefin composition is described, comprising: (A) a polyolefin which is modified with an unsaturated carboxylic acid or its derivative, or a mixture of such a modified polyolefin and a polyolefin, (B) aluminum or aluminum alloy in a powdery, fibrous and/or flaky form, (C) electrically conductive carbon black, (D) a halogen-containing organic compound and antimony oxide, and (E) a hydrous inorganic substance. This polyolefin composition has good electromagnetic wave-shielding properties and flame resistance, and therefore, it can be used as a housing material for electronic equipment.
