Uses
Potassium perfluorobutane sulfonate has wide uses for flame retardancy in synthetic materials, which especially is the best flame retardant for polycarbonate materials.
In thermoplastic materials , it is an efficient anti-static agent and flame retardant.
It can also improve the transparency of transparent resins such as polycarbonate, polystyrene, polyimide, polyester and polyamide.
