The organically modified montmorrillonite (OMMT)/phosphorus polymeic flame retardant (PFR)/polyamide 6(PA6) nanocomposites were prepared via melt intercalation on a twin-screw extruder. The structure formed in nanocomposite system was investigated by Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Transmission Electron Microscopy (TEM). Properties such as flame retardancy, notched impact strength, tensile strength, elongation at break and flexural modulus were studied by limited oxygen index (LOI) approach, UL94, and mechanical property test. The results of the studies indicated that flame retardancy and mechanical properties of PA6 nanocomposites were all reinforced due to addition of OMMT and PFR.

One way to improve the fire performance of polymers is by the development of intumescent systems. The addition of ammonium polyphosphate/polyamide-6 is known to provide flame retardancy in many polymers via an intumescent process. The development of appropriate formulations is limited by their mechanical properties. This study shows that polypropylene based intumescent blends are efficient fire retardant systems and that acceptable mechanical properties can be obtained. It is also shown that adding talc improves the mechanical properties of intumescent polypropylene formulations without decreasing their fire retardancy.
