Flame retardant and mechanical properties of ethylene-vinyl acetate copolymer (EVA) composites containing ammonium polyphosphate (APP) and its microcapsules, MFAPP with a shell of melamine–formaldehyde resin and EPAPP with a shell of epoxy resin, were evaluated in EVA. The results indicate that APP after the microencapsulation leads to an increase in LOI in EVA compared with APP. When dipentaerythritol is added into the EVA composites containing APP microcapsules, a further improvement in flame retardancy of the composite is observed. Moreover, thermal decomposition behavior and mechanical properties of the EVA composites are investigated.

AbstractThis study focused on realizing fire retardancy for polymer composites by using a cellulosic biofiller and ammonium polyphosphate (APP). The motivation of this study was based on revealing the mechanism of the synergetic effect of a cellulosic biofiller and APP and determining the parameters required for achieving a V-0 rating in UL94 standard regardless of the kind of polymer system used. As for the polymer matrix, polypropylene and polylactic acid were used. The flammability, burning behavior and thermal decomposition behavior of the composites were investigated through a burning test according to the UL-94 standard, cone calorimetric test and thermogravimetric analysis. As a result, the incorporation of a high amount of cellulose enabled a V-0 rating to be achieved with only a small amount of APP despite the variation of the optimum cellulose loading between the matrix polymers. Through analysis, the results indicated that APP decreased the dehydration temperature of cellulose. Furthermore, APP promoted the generation of enough water as a nonflammable gas and formed enough char until the degradation of the polymer matrix was complete. The conditions required to achieve the V-0 rating were suggested against composites incorporating APP and biofillers. Furthermore, the suggested conditions were validated by using polyoxymethylene as a highly flammable polymer.
