Insulation for fire-resistant cables

Under the registered trademarks Firox® and Pyronax®, COGEBI produces a range of tapes based on mica paper, reinforced with glass fiber fabrics.

These tapes have great flexibility and high tensile strength, and their combined characteristics mean they can be used to create inorganic, fire-resistant insulation for electrical cables.

Firox® and Pyronax®

Firox® and Pyronax® tapes are manufactured using Muscovite mica or Phlogopite mica, characterized by its high thermal resistance properties.

They have the following features:

• they have high tensile strength and good shearing and shock resistance
   
• their flexibility allows them to be used with the thinnest conductors
   
• they retain their exceptional properties at both very low and very high temperatures, in conditions which would make other materials unsuitable
   
• they do not give off fumes at high temperatures
   
• they maintain their insulating properties even at 1000°C / 1832°F
   
• they have high radiation resistance
   
• they can be applied through winding or lengthwise wrapping
   
• their use means cables comply with the following standards: IEC 331, EN 50200, BS 6387 S/Z/W, DIN 4102, NF C32-070, NB 30-004, MILC- 24640, MIL-C-25038/3, U.L.2196, Nec 760-2b, JFDB test n° 7, AS/NZS 1660 5.5, etc.
