Technology Development for Flame-Retardant Low-Smoke Material for Wire and Cables for Sheathing Applications

An attempt was made to develop technology for low-smoke flame-retardant cable and compound with elimination of toxic chemicals in the formulation. The extrusion trials using twin screw extruder and cable coating with single screw extruder were successful. Results of the evaluation of the cable and compound suggest that the composition seems to be satisfactory. However, large-scale production could not be taken due to the actual technoeconomic viability of the commercialization. This study paved the way for DSIR-sponsored project for commercial exploitation under PATSER scheme.
