The thermal endurance and the thermal degradation kinetics of a Polypropylene wood composite are studied. The study is done by using several kinetics analysis methodologies including the following: conventional TGA, modulated TGA, Flynn-Wall-Ozawa isoconversional analysis (ASTM E1641-07), thermal endurance (ASTM E1877-05) and Friedmad isoconvertional method. The thermal degradation of the Polypropylene wood composite is compared with the thermal degradation of pure Polypropylene and wood powder. Despite of a discoloration process, the temperature peaks of wood decomposition for the composite and for the wood power are coincident. On the other hand, the temperature peak of Polypropylene decomposition for the composite is shifted to higher temperatures.
