Thermal degradation and combustion of a polypropylene nanocomposite based on organically modified layered aluminosilicate

The specific features of thermal degradation and combustion of polypropylene nanocomposites based on organically modified layered aluminosilicate were studied. On the basis of thermogravimetric analysis data, a kinetic model that takes into account the diffusive character of the thermal degradation process for the PP nanocomposite was proposed. The basic flammability parameters of the nanocomposite were determined with the use of a cone calorimeter. The influence of diffusion constraints in the charred nanocomposite layer on the maximum heat release rate as a principal parameter of flammability was considered.
