Streszczenie / Summary:

The paper analyses effects of certain flame retardants (melamine, Exolit) on flammability and
fire properties of polyamide 6/montmorillonite nanocomposites and is based on research into melt
flow rate, oxygen index, UL-94 flammability and thermogravimetric analysis. The cone calorimeter
method was used to determine smoke and heat release rates, the ignitability hazard posed by the
material, smoke density and toxicity of the gas phase occurring during the decomposition of the
tested materials with the heat flux of 35 kW/m2. It was proved that Exolit-modified materials
provided more effective fire protection.
