摘要 |
A composition comprises a first polycarbonate having a limited oxygen index of greater than 26% measured according to ISO 4589 on a 4 mm thick plaque, wherein an article molded from the first polycarbonate has a smoke density after 4 minutes (DS-4) of greater than 600 determined according to ISO 5659-2 on a 3 mm thick plaque at 50 kW/m2; and a second polymer different from the first polycarbonate, the second polymer comprising a poly(carbonate-siloxane) copolymer, a polydialkylsiloxane, or a combination comprising at least one of the foregoing; wherein an article molded from the second polymer has a smoke density after 4 minutes (DS-4) of greater than 600 determined according to ISO 5659-2 on a 3 mm thick plaque at 50 kW/m2; wherein an article molded from the composition has a smoke density after 4 minutes (DS-4) of smaller than 480 determined according to ISO 5659-2 on a 3 mm thick plaque at 50 kW/m2. |

1. A composition comprising
a first polycarbonate having a limited oxygen index of greater than 26%, wherein an article molded from the first polycarbonate has a smoke density after 4 minutes (DS-4) of greater than 600 determined according to ISO 5659-2 on a 3 mm thick plaque at 50 kW/m2; and a second polymer different from the first polycarbonate, the second polymer comprising a poly(carbonate-siloxane) copolymer, a polydialkylsiloxane, or a combination comprising at least one of the foregoing; wherein an article molded from the second polymer has a smoke density after 4 minutes (DS-4) of greater than 600 determined according to ISO 5659-2 on a 3 mm thick plaque at 50 kW/m2; wherein an article molded from the composition has a smoke density after 4 minutes (DS-4) of less than or equal to 480 determined according to ISO 5659-2 on a 3 mm thick plaque at 50 kW/m2. |
