Shelf Life of
KLINGER gasket
material
Shelf Life of KLINGERSIL® gasket
material
KLINGERSIL® gasket material is as all
elastomeres and elastomere
containing material subject to a
natural ageing process. This process
is depending on the kind of elastomer,
its vulcanisation system and the
storage conditions.
Nevertheless unfavourable storage
conditions can lead to a premature
reduction of the materials quality.
Above all there is to mention elevated
temperature, too low humidity as well
as strong illumination.
The main factor undoubtedly is
the storage temperature. As
temperatures higher than 30°C
appears over a longer period, a
reduction of the material properties
can occur already after 2 years.
As an ideal storage condition we
propose:
As in this conjunction detailed
specifications are not possible, we
propose the conditioning of the
storage rooms as mentioned above.
For all KLINGERSIL® -sheets and
-gaskets the share of the elastomere
as binder is between 10 to 30%
according to DIN 28091-2. The
relatively small share of parts which
are subject to the ageing process
shows, that this influence on to the
whole product is smaller as on a
product of pure elastomer.
■ Temperature < 25°C
■ relative humidity 50 - 60%
■ darkened storage room
Shelf Life of KLINGERgraphit
laminate
Usually storage temperature, illumination etc. have no influence on the
storability period of KLINGERgraphit
laminate.
Nevertheless following conditions
should be realised to ensure
appropriate storage:
Under these conditions a period
of storage of approx. 5 years is
possible. Actually there is no chance
to define the changing of the storage
time due to changes of one of the
above influence factors.
Ready made gaskets should be
stored flat as, particularly for bigger
gasket sizes, tensions and distortions
can occur and complicates the
installation.
Under these conditions storage
times of over 10 years are to expect.
■ – 20 °C to + 50 °C storage
temperature
■ clean and dry air
(no dirt particles, no aggressive
gases or vapours)
■ sheets and ready made gaskets
have to be protected against
damaging
■ sheets and ready made gaskets
have to be stored flat
Certified according to
DIN EN ISO 9000:2000.
