The relative data were combined with flammability properties and the overall performance of the FRs was correlated with the type of branching in the polyethylene grades and to their processing behavior. The thermal degradation kinetics was further determined based on the Kissinger and Coats-Redfern methods. In terms of flammability, the addition of a triazine derivative and ammonium polyphosphate at a loading of 35 wt. %. was found to be the most efficient, leading to UL 94 V0ranking in the case of the LDPE grade produced in an autoclave reactor.enHalogen-Free Flame RetardantLow-Density PolyethyleneLinear Low-Density PolyethyleneIntumescenethermal decompositionflammabilityKissinger ModelCoats-Redfern Model620547journal article
