Abstract

Various flammability properties of a silicone-containing polycarbonate sample were measured and compared with those of a pure polycarbonate sample. The results show that peak heat release rate for the silicone-containing polycarbonate sample is significantly reduced (less than half) compared to that for the pure polycarbonate sample with two different sizes of sample, 10cmx10cm and 40cmx40cm. However, the ignition delay time for the silicone-containing sample is shorter than that for the pure polycarbonate sample. Also, the flame spread rate with external radiant fluxes for the silicone-containing sample becomes faster than that for the pure polycarbonate sample. The observed char behavior, such as char depth, physical nature and apparent combustibility, and its impact on flammability properties are discussed.
