1. A thermoplastic composition comprising:
(a) from about 10 wt % to about 80 wt % of a first polycarbonate; (b) an impact modifier composition from about 1 wt % to about 30 wt %, wherein the combined weight percent of components (a) through (b) does not exceed 100 wt %, wherein all weight percent values are based on the total weight of the thermoplastic composition; and (c) a mold release composition comprising at least two different mold release additives from about 0.01 parts by weight to about 1.5 parts by weight added to 100 parts by weight of the thermoplastic composition excluding the mold release composition, wherein one or more of the at least two different mold release additives comprises pentaerithritol tetrastearate, glycerol monostearate, glycerol tristearate, poly(alfa) olefin, poly(ethylene oxide-propylene oxide-ethylene oxide), or any combination thereof; and wherein a molded sample of the thermoplastic composition has better mold release performance compared to a substantially identical reference composition in the absence of the mold release composition, and wherein the presence of the mold release composition has substantially no impact on the mechanical and physical properties. |
