Percentage changes in smoke generation where the percentage change in total smoke release, ΔTSR% = [TSR(MC/PolyBrFR)/TSR(PolyBrFR) − 1] × 100 and TSR(MC/PolyBrFR) and TSR(PolyBrFR are the respective smoke release values for each metal compound (MC) in combination with each PolyBrFR and PolyBrFR alone in PA66: Red columns indicate an increase and blue columns a decrease in smoke generation with respect to that from either brominated polystyrene, BrPS, or poly(pentabromobenzyl acrylate), BrPBz, present in PA66 alone. AlW, SnW and ZnW = aluminium, tin (II) and zinc tungstates respectively; ATO = antimony (III) oxide and ZnS = zinc stannate.
