Fabrics for High Temperature Applications
The range of Fothergill Engineered Fabrics'
heat resistant materials
covers virtually all thermal insulation and
thermal protection applications.
They provide cost-effective and in many
cases safer alternatives to
fabrics in current use, since they contain no
asbestos or respirable fibres.
Tyglas glass fabrics are generally employed as
facings for flexible or rigid
insulation, having a maximum continuous operating
temperature of
550°C. Coated glass fabrics are available for use
in the fabrication of
flexible ductings,
expansion joints and explosion membranes, with
differing maximum continuous temperatures, depending
on the coating.
Special coated fabrics have also been
developed for fire blankets to BS
6575 (Tyglas FB)
and for covering insulation mattresses and valve covers
(Tyglas VC).
Tyglas 1000C These are texturised
glass fabrics which have been
specially treated and will withstand a blowtorch
flame in excess of
1000°C. Providing increased protection from molten
metal spatter, their
high strength and abrasion resistance makes
them eminently suited to fire
barriers and welding blanket applications.
Tygasil Produced in woven, knitted, and needled mat
form, Tygasil silica
fabrics have been subjected to a special treatment
which increases the
silica content to typically 98%, resulting in a
fabric which retains flexibility
at the maximum recommended operating
temperature of 950°C. These
fabrics are excellent for furnace curtains, fire
barriers, welding screens
and blankets.
Knitted TygasilCombining the features of woven silica with improved
flexibility and high insulation properties, knitted Tygasil contains no
respirable fibres. Assuring high
standards of worker safety and comfort, it
provides an efficient and cost effective
replacement for refractory ceramic
fibres (RCF's) in industrial insulation and heat treatment
operations
.
High Temperature Filtration Products Filter fabric technology has been
a speciality of
Fothergill Engineered Fabrics for almost forty years, since
the introduction of manufacturing from
monofilament polyester and other
yarns. Our technical staff
work closely with customers in the development
of specially treated glass fabrics for the
filtration of molten aluminum. The
impetus towards advancing fabric technology often
springs from
developing materials to satisfy our customers'
special requirements. In
this manner, aramid, quartz and other yarns are
included in our product
range.
Ceramic Fabrics Manufactured from NextelTMceramic fabrics,
offering a
maximum operating temperature up to 1600°C, these
fabrics are often
specified for furnace curtains, fire seals, fire
barriers and expansion joints.
Because of the ever increasing demand for
solutions to today's problems, we list below a range of
yarns with some of their technical merits.
Aramids
Giving good abrasion and
resistance to flexing with a
maximum continuous operating
temperature of 200°C.
Tyglas
Fabrics woven from 'E' glass
yarn are strong, incombustible
with a maximum continuous
operating temperature of up to
550°C in
static conditions.
Tyglas 1000C
Is a texturised
'E' glass fabric
coated with a special
formulation designed to
withstand continuous operating
temperatures of up to 1000°C
in static conditions.
Tygasil
Either woven, braided or knitted
silica fabrics are available to
provide heat protection and
retention of flexibility up to
950°C.
Ceramic/Nextel
Over 90% of room temperature
properties are retained when
fabrics are exposed to
temperatures up to 1100°C for
prolonged periods.
Temperatures up to 1400°C
can be withstood for short
periods.
