Bodies made of expanded graphite are impregnated with low-viscosity,
solvent-free, storage-stable, polymerizing resins from the group of
isocyanates and their co-reactants and/or epoxy resins up to resin
contents of 50% by weight. A primary product is made of expanded graphite
with an open pore system, with a particularly preferred range of bulk
densities of from 0.5 to 1.3 g/cm.sup.3 and with an ash value of not more
than 4% by weight. Such bodies can also contain a proportion of additives.
Sealing elements, components in fuel cells and heat-conducting elements
are formed of the impregnated, shaped and rapidly curable graphite bodies.
A process for producing such bodies is also provided.
