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.
