The
instrinsic electrical and thermal properties of fiber glass
fabrics were instrumental in their early acceptance in
high temperature electrical insulation. Combined with alkyd
varnishes, silicon resins, silicon rubber, PTFE, mica or
pressure sensitive adhesives and slit into tapes, these
products continue to be used widely in electrical equipment
of all kinds. Fiber glass fabrics in combination with thermosetting
epoxy resins constitute the basic raw material for printed
circuit boards, where the thermal, electrical, dimensional
stability and mechanical property contributions of fiber
glass fabrics to the laminate find maximum utilization.
Lightweight fiber glass fabrics are used extensively in
multilayer printed circuitry, imparting a high degree of
dimensional stability to these products as well as to flexible
electrical products.

Strength
contributions of fabrics combined with ease of fabrication
of composites has resulted in the acceptance of composites
in many industries. Many aerospace/aircraft components,
ranging from radome, wing-to-fuselage fairings and wing
flaps on exteriors to entire cabin and cargo hold interior
sidewalls, are made of fiber glass fabric reinforced thermosetting
resin composites, where high strength, low weight and part
reliability are necessary design criteria.
Fiber
glass fabrics are coated with extensive applications in
recreational consumer products, such as fishing rods, golf
club shafts, vaulting poles, skies, bows and arrows, protective
helmets, hockey sticks and antennas, among others.These
take advantage of fiber glass fabric's contribution
to strong lightweight flexible products.
The
uses of fiber glass fabrics in the manufacture of high strength,
corrosion resistant pipes has the advantage that large sections
of pipes can be quickly made compared to other pipe manufacturing
processes.
Woven
fiber glass products continue to find widespread applications
in both the marine and tooling industries.

Fiber
glass fabrics are coated with a variety of thermoplastic
resins, rubbers or elastomers for use in flexible air ducts,
air supported structures, conveyer belts, welding curtains
ceiling board facing, gaskets, pipe jacketing, pressure
sensitive tape, window shades, movie screens and the
like . We undertake coatings of PTFE, Silicon, Polyurethane,
PVC, EVA, acrylic, graphite,Viton,phenol formaldehyde.
Fiber
P.T.F.E coated fabric are generally available with both
side coating on closed and open surfaces in different thickness
and weight. For application that place high priority on
impermeability of P.T.F.E coatings, the surface can be laminated
with a fluoroplastic film which is under development.
Silicon,
PU, PVC, EVA are available in both side and single side
coating. PU is usable in the temperature range of -40oC
to +120oC. While Silicon coated fabrics can be
used without limitations in the temperature range of 60oC
to +220oC with the help of special additives,
its thermal resistance can be increased upto 250oC.
Viton
coated fabrics ,finds its application mostly in nonmetallic-expansion
joints and are available in both sided coated forms.
PVC
is the low cost material that is also suitable for high
frequency welding, and is widely used to coat polyester
fabrics.
Acrylic,
EVA are mostly used for imparting anti-fraying charcteristics
to fiber glass fabrics.
Graphite
used by KETEX has a highly specialised characteristics and
is used in conjunction with acrylic, P.T.F.E and sometimes
in pure form for imparting semi-conducting properties.

In
the above area Glass Fibre fabrics are still the most suitable
filter media for dust laden hot gases , as it possess the
best temperature resistant properties ,dimensional stability
,lowest elongation and is more easily heat-set.The fabric
woven out of continuous and texturised fibre glass yarn
is given special finishes to increase its abrasion-resistance
and its flexing properties.
Fibre
glass fabrics are found to be suitable for filtration of
molten Aluminium and alloys.Glass fabrics produced from
high twist yarn,ensure accurate maintenance of the pore
size and shape arrests oxides and inclusions simultaneously,which
promotes easy flow and resists the high temperature.Further,a
special ceramic coating is applied which holds the yarn
in position until set by -80oC - 710oC
pour heat.
