EXPANDABLE STYROLE POLYMER GRANULATES

摘要

The invention relates to styrole polymer granulates which are obtained by means of melt extrusion and have an almost spherical geometry and an elongated dimension (2) and shorter extensions (b and c) extending perpendicular thereto. The invention is characterized in that the shorter dimensions (b and c) measure between 0.3 and 1.8 mm and the ratio y of the shortest dimension (c) with respect to the longest dimension (a) ranges from 0.8 to 1.
