DALFRATEX® is a range of inorganic fibres and textiles that are capable of operating continuously at 1000°C and up to 1600°C for limited periods. They will not melt or vaporize until temperature exceeds 1700°C, and have a
high resistance to thermal shock.
DALFRATEX® products also provide flexible electrical insulation at temperatures as high as 1000°C. Products are available as textile cloths,
tapes, sleeving, cords, braided packing, ropes and also as bulk fibres and batts.
DALFRATEX® products are composed of continuous filaments of amorphous silica, which combine the flexibility of fibres and textiles, with
the refractory properties of silica. In order to service the needs of a wide range of applications the majority of DALFRATEX® products are available in two basic forms: standard and pre-shrunk. The standard form shrinks during initial heating and products of this type have letter ‘U’ incorporated into the code
number. As their name implies, the pre-shrunk forms have been factory treated to confer better dimensional stability in high temperature use. In
addition to these forms a wide range of sacrificial organic finishes are available which may be applied to particular products where required for
specific end uses.
