Main Application
Potassium Perfluorobutanesulfonate is an important additive used in thermoplastics processing. It can be fully combined with transparent plastic resins such as polycarbonate, polyimide, polyester, polystyrene, polyamide, polyketone and ABS. It does not alter the inherent properties of the base materials and can even enhance their transparency, leading to a wide range of applications.
