“…The incorporation of flame retardant additives into the EVA is a well-known way to improve its low fire resistance. The effect of diverse flame retardants on the flammability of EVA has already been investigated [11][12][13][14][15][16][17][18][19][20][21][22]. During recent years, researchers fascinatingly tested the combination of conventional flame retardants like phosphorous ones with mineral fillers and/or nanoparticles.…”

Nowadays, researchers working in the realm of coating or related industries are expected to propose novel materials with multifunctional capabilities. In this work, novel nanocomposites based on poly(ethylene-co-vinylacetate) (EVA) copolymer, hydroxyapatite (HA), carbon nanotubes (CNTs) and ammonium polyphosphate (APP) are proposed and examined for thermal stability and flammability. Thermogravimetric analysis and cone calorimeter tests evidenced that HA/CNTs combination presents a promising effect on both thermal and flame retardancy behavior of EVA. Cone calorimeter results approved in a similar manner that the incorporation of only 5 wt.% HA-CNTs into the EVA significantly drops peak of heat release rate (pHRR) (around 37%). The flame retardant effect was further improved when HA or HA-CNTs were associated with APP. The pHRR decreased by 76-77% for EVA containing HA or HA-CNTs and APP compared to the neat EVA. The performance of developed nanocomposites was compared with more than 100 flame retardant systems previously reported in the literature.

“…The fire behavior of EVA has been extensively studied over recent years. In this regard, the effect of different "additive flame retardant" systems on the flame retardancy of EVA has been investigated [3][4][5][6][7][8][9][10][11]. Among flame retardants incorporated into EVA, metallic hydroxides, magnesium hydroxide (MDH) and alumina trihydrate (ATH) have been comprehensively studied in view of their exceptional efficiencies.…”

This work seeks to address the effect of simoultaneous use of three flame retardants, having three different modes of action, (magnesium hydroxide, expanded and expandable graphite) on the thermal degradation and flame retardancy of poly(ethylene-co-vinyl acetate). Thermal conductivity of samples was meseaured in order to investigate the effect of the use of expanded and expandable graphite on the time-to-ignition and the peak of heat release rate in cone calorimeter test. Thermal shielding performances of chars were studied as well. It was found that there is an optimum ratio between expanded and expandable graphite in order to control thermal conductivity and therefore fire properties. Some correlations were also found between the char thickness and the first peak of heat release rate.

“…[8][9][10][11] On the other hand, traditional halogen-free flame-retardants containing P and N elements often degrade the physical and mechanical properties of resins. [12][13][14][15] Some nanomaterials can overcome the above-mentioned shortcomings, but their high surface energy and strong aggregation tendency make them less effective, [16][17][18] as evidenced by a poor performance in traditional evaluations such as the UL-94 test. Overall, the ideal flame-retardants should be halogen-free, efficient, environmentally friendly, and maintain the mechanical properties of composites.…”

A metal-organic framework (MOF) formed between Zn and p-hydroxybenzoic acid (PHBA) is synthesized using a solvothermal method. These Zn-PHBA nanorods, which are inexpensive and suitable for mass production, are added as a flame-retardant into vinyl resin (430 LV, a material used in marine composites). Data from cone calorimetric test demonstrates that adding the Zn-PHBA nanorods to 430 LV significantly improves flame retardation and smoke suppression. At a high Zn-PHBA content of 10.0 wt%, the limiting oxygen index of 430 LV increases from 19.5% to 28.5%, and the material reaches the V-0 rating in vertical burning tests (UL-94). Moreover, the tensile and impact strengths of 430 LV containing 10 wt% Zn-PHBA as flame-retardant do not deteriorate and are even slightly improved. This work demonstrates that this MOF synthesized by a simple and efficient method may be used to produce nanocomposites with excellent flame retardation and mechanical properties, while keeping the material cost sufficiently low for marine applications.
