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.
