Abstract

The use of polyamide coatings for electrical applications is restricted mainly because of its inadequate flame retardant behaviour. In order to improve its flame retardant behaviour, polyamide is modified by incorporating phosphorus moiety in its backbone. The structure of the phosphorus and poly amide was confirmed by infrared spectroscopy (FT-IR), NMR, thermo gravimetric analysis (TGA), differential scanning calorimetry (DSC), UL-94 vertical burning tests and char residue tests. From the results obtained, we observe that the incorporation of phosphorus into the polyamide enhances its thermal stability and flame retardancy.
