Empirical classification

Nanosync HFFR compounds exhibit an increasing fire retardancy level from 1 to 5 and this empirical classification is based on a cone calorimeter data analysis rather than a LOI (Limiting Oxygen Index) measurement.

We have decided not to mention the LOI value of our HFFR compounds, as it could mislead cable manufacturers in evaluation of real fire retardant performances of our compounds, compared to a standard HFFR material with LOI 35, to which it was arbitrarily attributed a fire retardancy level 0.




Above industry limits


The highest fire retardancy level 5 of the compound can be achieved through application of our novel flame retardant masterbatch additive NSMB 503, which can be applied in a variable amount from 1% to 10% together with a compatible Nanosync HFFR base compound, f.ex. FPC 301 with fire retardancy level 3, in a single screw extrusion.

The final retardancy level will depend on the cable design, but certainly the high fire reatardancy level compounds FPC 301 and FPC 400, will grant a very good reaction to flame as they form strong char during fire with consequent low emission of heat and smoke and without the formation of flammable droplets.

Please note that NanoSync’s HFFR compounds are softer than competitor materials and exhibit reduced formation of plate out / dye drools / dye buildups on the dye head during extrusion.
