Abstract
In the manufacture of PVC cellular plastic, a liquid plastic mixture is admixed with fibres in an amount of at most 0.050 percent by weight fibres, preferably carbon fibres having a length of about 1 cm, which fibres are distributed in the expanded cellular plastic isotropically with respect to both position and alignment. The cellular plastic is effective to dampen electromagnetic radiation within the radar range to at least 1-3 dB per cm.
