KLINGERgraphite - laminate PDM

Better handling
and a much higher capability

1. Higher stability due to
two tanged stainless steel sheet

Due to the improved connection of the
graphite and the two tanged stainless
steel sheets the new KLINGERgraphite-
laminate PDM offers a higher
stability and deformation resistance.
2. Optimal handling
Due to the increase in density we
did away with impregnation.
The new KLINGERgraphitelaminate
PDM has a purity of 98% and
is free of resins, impregnations, or
other organic substances and therefore
free of possibly toxic residual risks.
3. Clearly more safety
Gaskets made of the new
KLINGERgraphite-laminate PDM offer
more safety during fitting and whilst
under operation.

Due to the higher compression, the KLINGERgraphite-laminate PDM has a thickness of 1.5 mm, even where
2.0 mm-graphite gaskets were previously used.
The final thicknesses are the same in compressed condition.
Anti-stick finish:
The KLINGERgraphite-laminate PDM is available with KLINGERantistick (A/S) a finish which keeps its stability
even at high temperatures and causes no organic contaminations of the pure graphite.
* In case of supply shortfall also 1.4404 may be delivered.
