Applications

Flame Retardant Additive KFBS is chemically and thermally stable to temperatures greater than 450°C and is therefore suitable for use in engineering resins that require high processing temperatures. Flame retardant additive has been found an effective flame retardant in polycarbonate at levels as low as 0.06-0.08% by weight. Due to the low levels required to achieve performance and its effective solubility in polycarbonate, additive can be formulated to produce an optically clear, hazefree grade of polycarbonate for extrusion and molding.
