 GORE-TEX
GR®
Style R sheet gasketing is manufactured using Gore's unique
proprietary expanded polytetrafluoroethylene (PTFE) process.
Its multidirectional strength inhibits creep and cold flow
and also limits the possibility of blow out. GORE-TEX GR®
Style R sheet gasketing is a development based on GORE-TEX
GR® sheet gasketing. It provides a 6 fold increase in bend
resistance making large gaskets considerably easier to handle.
GORE-TEX GR® Style R gaskets are ideal for installation in
difficult pipeline locations. GORE-TEX GR® Style R sheet gasketing
is suitable for rough or damaged flange faces. Once installed,
gaskets cut from this material seldom need retorquing and
give long lasting performance. Universal chemical resistance
allows GORE-TEX GR® Style R sheet to be used in virtually
any application. Excellent results can be achieved with limited
bolt-forces and irregular or fragile flanges, e.g. glass or
plastic.

 GORE-TEX
DF
joint sealant manufactured using Gore's patented expanded
PTFE process has an expanded fibre structure providing excellent
mechanical advantages. Despite the materials conformability,
it still remains stable at high pressures.

 GORE
TAPE PRODUCTS are
the third generation of PTFE form-in-place gasketing. This
material is a multi-directionally orientated form-in-place
gasket which has high tensile strength in both transverse
and longitudinal directions resulting in very low relaxation
properties. Due to the high strength in the transverse direction,
the gasket profile does not have the tendency to increase
in width during precompression and service, even at elevated
temperatures.

TECHNICAL DATA |
Material : 100% expanded PTFE with high multi-directional tensile strength
Operating Temperature Range : -240ºC to +270ºC(to+315ºC
for short periods)
Chemical Resistance : Resistant to all media
in the range 0-14pH, except molten alkali metals and elemental
fluorine, particularly at elevated
temperatures
Stability : Not subject to ageing and storage
life is limited only by the adhesive backing. A shelf life of
no more than two years is recommended.
Maximum Permissible Gasket Stress : 150 MPa
Typical Applications : Glass lined vessels,
glass lined reactors, pressure filters, large pressure vessels,
large directional flanges with severe irregularities and heat
exchangers.
Size Selection & Installation : GORE TAPE
has a self-adhesive backing strip on one side for fixing on
the flange during installation. For standard steel flanges the
gasket width should be as close as possible to the width of
the sealing surface. For optimum sealability the available bolt
force and the flange design should also be taken into consideration
when selecting the correct gasket width. The optimum thickness
of the tape is three times the maximum irregularity of the sealing
surface, For glass-lined steel flanges the gasket tape width
should be equal to, or greater than, the full width of the glass
lined flange. |
