Abstract: Thermoplastic compositions include: (a) from about 20 wt % to about 50 wt % post-consumer recycled polycarbonate (PCR-PC); (b) from about 5 wt % to about 25 wt % of a filler component; (c) from about 4 wt % to about 7 wt % of a phosphazene component; (d) from about 20 wt % to about 65 wt % of a polycarbonate copolymer component; and (e) from about 1 wt % to about 20 wt % one or more additional components. The polycarbonate copolymer component includes bisphenol-A and a monomer comprising one or more of 3,3-Bis(4-hydroxyphenyl)-2-phenyl-2,3-dihydro-isoindol-1-one (PPPBP), 4-4-(3-3-5 trimethylcyclohexane-1-ldiyl)diphenol (BPI), 4,4′-(1-Methyl Ethyl) 1-3-cyclohexandiyl) Bis-Phenol (BHPM), 1,1-Bis(4-hydroxy-3-methyl phenyl) cyclohexane (DMBPC); 4-[1-(4-hydroxyphenyl)cyclododecyl]phenol (Red Cross), bisphenol based on cyclooctadiene, bisphenol based on isophorone nitrile, and combinations thereof. The thermoplastic composition exhibits improved heat properties, including but not limited to heat deflection temperature.
