Kinetic analysis of the thermal degradation of an intumescent fire retardant coated green biocomposite

•Thermal degradation of green biocomposites can reduced using a fire retardant.•Ammonium polyphosphate-tris (2- hydroxyethyl) isocyanurate (APP-THEIC) and boric acid forms an intumescent fire retardant system to protect the underlying material against fire.•Thermo-analytical investigation measures changes in signal with the course of chemical processes and reflects the kinetic nature of the changes taking place in the process.•Expended prout-Tompkins solid-state reaction model is used to determine kinetic parameters using NETSCH thermokinetics.•Scanning electron microscopy and energy dispersive spectroscopy are used to carry out the morphological analysis of the thermally degraded material.
