DALFRATEX®

PROPERTIES & ADVANTAGES

  • Good electrical insulation
  • High electric strength
  • Low electrical conductivity
  • Compatible with mineral acids (except phosphoricand hydrofluoric)
  • Compatible with a wide range of substances (air, chloride, carbon monoxide, ammonia and sulphur dioxide)
  • Compatible with silica refractories at high temperatures

Inorganic fibres and textiles for commercial aviation and aerospace

DALFRATEX® is a range of inorganic fibres and textiles. The materials are capable of operating continuously at 1000°C and at up to 1600°C for limited periods. They will not melt or vapourise 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. They are composed of continuous filaments of amorphous silica, which combine the flexibility of fibres and textiles, with the refractory properties of silica.

The majority of DALFRATEX® products are available in two basic forms, i.e. standard and pre-shrunk.
