Potassium Perfluorobutane Sulfonate Nonafluorobutane-1-sulfonic acid potassium salt (PPBS) Chemical name: Nonafluorobutane-1-sulfonic acid potassium salt (Potassium Perfluorobutane Sulfonate) FR-PPBS is extremely effective as a flame retardant additive with premium performance in polycarbonate at very low additive levels. FR-PPBS has been found to be an effective flame retardant in polycarbonate at use levels as low as 0.06%~0.08% by weight. It is chemically and thermally stable to temperatures greater than 450 centigrade, making it suitable for use in engineering resins that require high provides excellent performance without affecting the processability of the resin. One advantage of the low use levels necessary to provide effective flame retardance is that FR-KPBS flame retardant additive can be formulated to produce optically-clear, haze-free grades of polycarbonate for extrusion and molding. What's more, FR-PPBS additive does not contain any bromine or chlorine and has been found effective as a flame retardant without the use of synergists.
