主权项

1. A polymer composition comprising:
a polycarbonate polymer present in an amount of about 20 weight % to about 80 weight % relative to the total weight of the polymer composition; a polycarbonate-siloxane copolymer present in an amount of about 1 weight % to about 20 weight % relative to the total weight of the polymer composition; a reinforcing filler present in an amount of about 15 weight % to about 35 weight % relative to the total weight of the polymer composition; and a flame retardant present in an amount of about 4 weight % to about 20 weight % relative to the total weight of the polymer composition, wherein the flame retardant comprises phosphorus, wherein the combined weight percent value of all components does not exceed about 100 wt %.
