We investigated factors affecting the combustion products diffusion processes intensity in polymeric heat-insulating materials under fire conditions.

We disclosed the content of activation and fluctuation approaches to the description of combustion products diffusion process in polymeric materials. We identified the effect of polymeric materials vitrification process on diffusion processes intensity. We analyzed interaction mechanisms of combustion products with polymeric materials.
