The ultimate fire protection for wire and cable industry.


Since the introduction of the first halogen free flame retardant compounds in the cable industry in the early 90ties of last century, the market has not seen any revolutionary innovation like that of Favuseal. A plastic based material with thermoplastic processing properties, yet resisting blazing fire conditions up to 1500 °C with a heat flux of more than 350 kW/m2! It is not a surprise that Favuseal is already used “powering” fire protection products in the off-shore industry and it is now rapidly gaining a firm position in the Wire & Cable market.

Plastic or Ceramic?

The key features of Favuseal are the (endothermic) phase transitions at 200°C and at 800 °C. This causes the material to expand and swell to two times its original volume. During the second transition a dense cellular ceramic network is formed. The result of this reaction phase is a solid material with extreme heat isolating properties up to 1500°C. Consequently it acts as a robust barrier to fire and heat.

Plastic and Ceremics

Favuseal is very versatile. It can be used in a wide range of cables, from fiber optical cables to medium voltage cables. Circuit integrity is vital in communication and power systems, especially in the case of a fire. Favuseal “powered” cables will survive heavy fires and will ensure ongoing operation for several hours.

Technology beyond char integrity

Favuseal can be applied as an inner jacket or a bedding material, added as a filler element or wrapped around existing cables as a retrofit job, thus giving fire protection for all critical areas of a cable design.

Technology beyond char Integrity

Several design examples are available on request. Favuseal is free of halogens and heavy metals. It is non-toxic in “any state”. It can be processed by conventional production methods like extrusion, compression molding and injection molding.

Design Examples

Favuseal is being used in power cables (low voltage, medium voltage), instrumentation cables and optical fiber cables. Used as a bedding material in power cables, Favuseal will improve the fire performance of the cable without compromising the regular design rules or international standards (IEC 60502). In the off-shore market where the cable specifications are dominated by the Norwegian NEK606 TS2009, the application of Favuseal is crucial to pass the Jet Fire test for hydrocarbon fire (HCF) resistant cables.

Halogen free materials were first introduced in the market for communication cables due to the fact that corrosive fires could have a destructive impact on the electronic equipment in switchboard stations. Fire safety demands got more stringent (IEC 60332-1, IEC 60332-3) and led to improved materials with better char integrity. With Favuseal a new innovative generation can be added to the family of halogen free compounds. Optical fiber cables protected with Favuseal will pass IEC 60332-3-22 Cat. A and can offer circuit integrity, without the disadvantage of being rigid and inflexible like corrugated steel cables.
