Résumé : |
Fire Spread along electrical cables may be mitigated through application of Flame Retardant Smoke Suppressant (FRSS) intumescent coatings as fire protective layers to electrical cables as well as by using FRSS additives based PVC compositions for sheathing of electrical cables. Metal based organic (MBO) complexes of Mo+6 and Cr+3 were used as FRSS in the present study. FRSS intumescent coatings were applied on cables and their fire performance was evaluated using national and international standard procedures. The coated cables did not show any surface spread of flame on exposure and the generation of smoke was also found to be very low. Plasticized PVC compositions were prepared and found to have excellent smoke suppression. The limiting oxygen index was found to be fairly high both for the PVC compositions and the intumescent coatings developed. |
