Applications and Compounding:

Flame Retardant Additive Potassium Perfluorobutane Sulfonate is extremely effective as a flame retardant additive with premium performance in polycarbonate at very low additive levels.

There is limited data to suggest that flame retardant additive Potassium Perfluorobutane Sulfonate may have utility at varying performance levels and higher addition levels in other engineering resins.

For most effective incorporation it is recommended the additive be initially dispersed into a 10% or more masterbatch and then compounded into the final plastic blend. Dispersion can be achieved effectively with typical polycarbonate processing equipment.
