Abstract
Mouldings containing expanded expandable graphite are characterised in that they additionally contain acid phosphates of metals of group 2 and/or 3 of the periodic table of the elements and/or pyrolysis products thereof. Such mouldings are distinguished by the fact that they have low odour and are mechanically stable, and, when in contact with water, do not have pH values which are too low.
