Fire behaviour of EPDM/NBR panels with paraffin for thermal energy storage applications. Part 1: Fire behaviour

Fire behaviour of EPDM/NBR panels with paraffin for thermal energy storage applications. Part 2: Analysis of the combustion residues

“…From XRD analysis it was verified the formation of silicon phosphate from the reaction of ammonium polyphosphate with the montmorillonite, while using the AP423 as FR due to the higher phosphorus content with respect to AP766. The observed interactions can explain the beneficial effect related to the presence of montmorillonite and of the envelope and the best performances of fire retardant AP766 observed in the first part of this work [37]. From SEM images it was possible to observe the different morphology of samples with and without FR: samples with FR were characterized by the presence of holes probably caused by the degradation of FR, while samples without FR by a more homogeneous structure.…”

“…Also the use of kaolin leads to a synergism when combined with intumescent flame retardants (APP + pentaerythritol + melamine), as it was verified by Thuechart et al [36]. Considering the possible application of EPDM/NBR paraffin panels for building applications, characterized in our previous work [23], and the risks associated to the use of such materials in case of fire, the fire behaviour of these rubber panels was deeply studied, and the effects of four different flame retardants were compared and reported in the Part 1 of the research [37]. In order to shed more light on the combustion mechanisms, the best two compositions were selected for further investigations, as Part 2 of the research.…”

“…In this work the combustion residues of three selected samples tested through cone calorimeter in Part 1 [37] have been studied. For the detailed description of the preparation of composites the reader is invited to refer to the previous paper.…”

Application of Halogen-Free EPDM Flame Retardants

“…Inorganic phosphorus flame retardants can be commonly used as rubber flame retardants include four kinds: phosphate, microencapsulated red phosphorus, red phosphorus and ammonium polyphosphate. Pegoretti et al studied the fire performance of elastomer panels prepared with EPDM for the first time [10]. These panels could be prepared with four different flame retardants.…”
