Vermiculite Applications
Friction Materials

Since the earliest
days of asbestos
replacement
programmes in the
automotive brake
industry, Dupré
Vermiculite has
worked closely with
the Research and
Development
departments of
Europe's major brake
linings
manufacturers on
projects involving
the uses of
exfoliated ver
 miculite
in friction linings.
Over the years Dupré has defined friction market needs, and refined manufacturing processes and quality control procedures to meet those needs. Supplying high quality vermiculite to customers specifications, Dupré enjoys 'Category A' or 'Preferred Supplier' status in the brake linings market.
Fibre free
and
completely
safe, the
benefits of
using
vermiculite
in brake
lining
formulations
are now
clearly
understood,
and it's
usage well
established.
During the
mixing
process, the
use of
vermiculite
helps to
achieve a
more
homogenous
mix. A high
temperature
insulant,
vermiculite
provides
useful
thermal
resistance,
and due to
the platey
nature and
surface
characteristic
of the
material, it
tends to
lock
together
under
compression
during wet
or dry, cold
or hot
processes,
to form an
effective
platform for
the matrix
or other
materials in
the
formulation.
 Dupré
Vermiculite
supply
exfoliated
vermiculite
in five
different
standard
grades, and
to
customer's
specific
requirements
of bulk
density,
particle
size
distribution
and moisture
content.
Ground or
micronised
vermiculite
powders can
be produced
to
specification
as required.
