Abstract
The invention relates to a plastic granulated material containing electrically conductive fibres, the degree of dispersion of which fibres in the granulated material is 0.10 at most, the degree of dispersion being the reciprocal value of the volume fraction in % of a granule occupied by electrically conductive fibre bundles and measured according to the threshold value method. Moulding compounds produced from the granules according to the invention have very high EMI values.
