Potassium perfluorobutane sulfonate

At General Electric, it was found that very low additions ( < 1 wt%) of alkali or alkaline earth metal salts of certain arylsulfonates provide self-extinguishing performance to PC. Potassium diphenylsulfone sulfonate, sodium trichlorobenzene sulfonate, and potassium perfluorobutane sulfonate are effective in PC at one-tenth of a per cent level and these salts are used on a commercial scale. The salts are mostly active in the condensed phase where they strongly destabilize PC upon heating, thus promoting last decomposition and melt flow which removes heat. 

The 3M Company has developed a flame retardant based on potassium perfluorobutane sulfonate (PSBK) for use in clear polycarbonate. PSBK is effective at 0.08 wt% compared to the 8-10 wt% levels typically used for brominated species.
