Dalfratex®

TEXTILES

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 vaporise 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 preshrunk. 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.
