Peak heat release rate nanofillers

The major approach now for EVA compounds, especially those designed for cable jackets, is the introduction of nano-clays to the mix. As little as a 3% loading of a nanofiller produces a marked effect on heat release. 5% of nanofiller reduces the peak heat release rate by almost 50% as well as shifting that peak towards longer time-lapse. The flame retardant properties are due to the formation of a char layer that acts as a Arm insulating layer and dramatically reduces the emission of volatiles towards the flame front. The silicate layers not only play the active role in char... 

In addition, several studies have reported the use of conventional ATH in combination with other types of nanofillers, particularly organoclays, to improve the FR properties of polymer nanocomposites [12, 13]. Organoclays are not considered as FR despite their ability to decrease peak heat release rates of several polymers under firelike conditions...
