Abstract
A completely non-halogenated flame retardant polycarbonate compound includes polycarbonate, non-halogenated termini-functional chemical such as vinyl-terminated siloxane and non-halogenated hydride-functional polysiloxane as non-halogenated drip suppressant ingredients which react in the presence of heat to form a drip suppressant adduct, and potassium 3-(phenylsulfonyl)benzenesulfonate as a non-halogenated char former. The compound can achieve a UL 94 rating of V-0 at a thickness of at least 3.2 mm and otherwise achieves no dripping/igniting of the cotton indicator during that test.
