Abstract
A polycarbonate composition includes the following components in parts by weight: a. 30 to 87 parts of a PC resin; b. 8 to 50 parts of a rubber-modified graft polymer; c. 5 to 25 parts of a fire retardant; and d. 0 to 10 parts of other aids; wherein a sum of parts by weight of the four components a, b, c, and d is 100. Phenols which are added in a polycarbonate composition formula, based on a total weight of the polycarbonate composition does not exceed 100 ppm. A K value of a component I of the PC resin is adjusted between 300000 and 500000 and the K value of a component II is adjusted to be less than 300000.
