18 Claims

1. A composition comprising:

from about 70 wt. % to about 98 wt. % of a polycarbonate polymer component;

from about 0.01 wt. % to about 1 wt. % of a flame retardant additive, wherein the flame retardant additive is free or substantially free of bromine and/or chlorine;

from about 2 wt. % to about 20 wt. % of a non-bonding glass fiber; and

from about 0.01 wt. % to about 5 wt. % of a stabilizer component wherein the stabilizer component comprises tetrakis(2,4-di-tert-butylphenyl)-4,4-biphenyldiphosphonite (PEPQ),

based on a total weight of the composition,

wherein a molded sample formed from the composition exhibits a multi-axial impact (MAI) rating energy at max force of greater than about 60 Joules at 23 degrees Celsius (° C.) when tested in accordance with ISO6603 standard and wherein a molded sample of the composition achieves a V2 rating at a thickness of about 0.8 mm UL 94.
