Fabrics
made of KETEX Texturised Fibre glass yarns are superior to
comparable products of asbestos in every aspect. A table is
reproduced here based on the results obtained by one of the
manufacturer of fire proof fabrics :

From
the results , fabrics made of texturised glass fibre yarns
can give :
|
Over
150% higher resistance to heat
|
|
Over
three times more strength
|
|
Twice
the resistance to heat transfer
|
|
50%
more abrasion resistance
|

than
, comparable fabrics made of asbestos.
Further
fabrics made with texturised glass fibre yarns are not only
stronger but they also retain much higher strength at elevated
temperatures compared to asbestos products.

below shows variation of tensile strength with temmperature
for fabrics made with texturised glass fibre yarn & asbestos.
